The Punchline

This is a live-match CS2 esports in-play trader with genuine directional edge. Every market is Counter-Strike 2. Every slug is a CS2 event. The entire book is built on real-time match state reads - watching a BO3 series unfold map by map and building positions as the live score shifts the Polymarket CLOB away from true probability.

The mechanism is not speed. It is knowledge. When the trader commits at 3x+ dominance, the dominant side wins 93.2% of the time across 59 markets. That is not luck and it is not market-making - it is someone who understands CS2 match dynamics at a level the orderbook has not priced correctly in the moment.

The account total of +$20,457 combines two revenue streams: +$15,200 from trading (picking the right team in live CS2 markets) and +$5,257 in Polymarket liquidity rewards. The trading edge alone is real and persistent across the 12 active days. The rewards are a bonus on top.

The overall picture: a specialist human or semi-automated trader who watches live CS2 matches, builds asymmetric two-layer positions (map-level and match-level simultaneously), exits aggressively when the market moves in their direction, and holds the residual to resolution. Win rate of 70.3% on resolved buys is correct for a strategy that concentrates capital in the $0.70-$0.90 range (where win rates are 91% and 93% respectively) while also taking smaller positions in the $0.40-$0.60 range for leverage.

What He Trades

The universe is Counter-Strike 2, exclusively. One category, one game, multiple tournaments running concurrently.

The tournament mix in the sample includes:

• Stake Ranked Episode 2 Playoffs (magic vs NIP, NIP vs FaZe)
• Stake Ranked Episode 3: Closed Qualifier Playoffs (FOKUS vs CYBERSHOKE, JiJieHao vs Phantom, Walczaki vs Oxuji)
• NODWIN Clutch Series Playoffs (Nuclear TigeRES vs K27, Gentle Mates vs Nuclear TigeRES, TDK vs Team Nemesis)
• NODWIN Clutch Series Group Stage (Walczaki vs KOLESIE, ex-RUBY vs RUSTEC, TDK vs Atreides, SPARTA vs AM Gaming, Betclic Apogee vs ASTRAL)

Market structure: 103 markets across 36 events = 2.86 markets per event on average. This confirms the two-layer approach: for a BO3 series, the trader opens positions in the individual map markets (Map 1 Winner, Map 2 Winner, Map 3 Winner) and the match-level BO3 outright simultaneously. Both layers move as the live match score updates.

Market structure per event (typical):
  cs2-[teams]-[date]           → BO3 outright winner
  cs2-[teams]-[date]-game1     → Map 1 Winner
  cs2-[teams]-[date]-game2     → Map 2 Winner
  (Map 3 only if series goes 2-2 in maps)

There is no other category. No crypto, no politics, no other esports, no sports. This is a pure CS2 specialist.

The top 10 markets by volume show highly variable P/L outcomes across similar trade counts, suggesting the P/L driver is match-level directional accuracy, not a systematic strategy applied uniformly:

NIP vs FaZe is the clearest single-match blowup: the BO3 outright lost -$2,639 and Map 2 lost another -$955, for a combined -$3,594 on that match. The trader read FaZe wrong and went large. This is the characteristic bleed of a high-conviction strategy - when the read is wrong, the losses are proportional to the confidence.

The Order of Operations - One Match, Trade by Trade

The JiJieHao vs Phantom match on June 18 (cs2-jjh-pha-2026-06-18) is the richest single-event trace in the CSV, spanning approximately 40 minutes of live trading across both the BO3 outright and the Map 2 Winner market.

Context: JiJieHao vs Phantom, Stake Ranked Episode 3: Closed Qualifier Playoffs. The BO3 outright had Phantom as the dominant side throughout the trader's activity. The Map 2 market oscillated - the trader built positions on both JiJieHao (underdog) and Phantom (favorite) at different points as the map score shifted.

Selected key fills, Map 2 Winner market (cs2-jjh-pha-2026-06-18-game2):

The pattern is clear: the trader builds a large position on one side (JiJieHao or Phantom) as a round sequence makes their probability diverge from fair value, sells aggressively when the market reprices toward their view, then rebuilds or pivots based on the next round sequence. This is live round-by-round scalping, not pre-match bet placement.

The parallel BO3 outright fills show the same timing: large Phantom BUYs at $0.60-$0.75 starting around 13:57 and a 682-share BUY at $0.60 at 14:04:31 (the single largest Phantom fill in the window at $414.26 USDC) just as the JiJieHao map 2 position is being unwound. The trader knows Phantom winning Map 2 affects the BO3 probability, so both books are managed simultaneously.

Phantom won Map 2 and the BO3. The resolved side in both condition IDs is "Phantom."

Why It Works - The Math

The strategy's edge is two-stacked:

Layer 1: Directional accuracy at high conviction. The dominance ratio data is unambiguous:

1.0-1.5x conviction:  50.0% win rate, $1.145 mean paired cost
1.5-2.0x conviction:  37.5% win rate, $1.038 mean paired cost
2.0-3.0x conviction:  77.8% win rate, $1.050 mean paired cost
3.0x+ conviction:     93.2% win rate, $1.083 mean paired cost

The 1.5-2x bucket's 37.5% win rate is actually below the base rate on a 70/30 coin - these are the exploratory fills and hedging legs, not the primary calls. The 3x+ bucket is where the P/L is made. At 93.2%, the trader correctly identifies the map winner from live match information in roughly 19 of every 20 high-conviction markets.

Layer 2: Active exit management. Like SirMartingale's SELL engine, Aaa298 does not hold purely to resolution. The June 18 trace shows repeated buy-sell cycles within a single match window, extracting realized gains before the market finalizes. When the round score moves in the trader's direction, the orderbook reprices and the trader sells into the lift. This converts unrealized wins into locked cash.

Expected value of a 3x+ dominant leg:
  Win probability:     0.932
  Avg dominant price:  ~$0.75 (capital-weighted, favored side focus)
  
  EV per $1 spent at $0.75:
    Win: $1.00 payout - $0.75 cost = +$0.25 gain
    Loss: -$0.75 loss
    
  EV = 0.932 × $0.25 - 0.068 × $0.75
     = $0.233 - $0.051
     = +$0.182 per share
     = +24.3% expected ROI per dominant-side share at $0.75

For 59 markets at $190K capital (high-conviction filter):
  Expected P/L = $190K × 0.0781 = +$14,860 (matches filter output of +$14,880)

The math checks out. The high-conviction filter captures almost all of the trading P/L (+$14,880 of the $15,200 total) on 57% of the trades. The rest of the book (sub-3x) is essentially breakeven noise.

---

Phase 1 - Trader Profile

Trade size distribution:

The mean ($80.93) is 3.5x the median ($22.97), indicating a right-skewed distribution with a long tail of large anchor fills. The P99 at $938 and max at $9,151 show that when conviction peaks, the bet size grows dramatically. The top 5% of fills carry 44.8% of capital - moderate-to-high concentration, consistent with a strategy that reserves large clips for the highest-confidence moments.

Execution signature:

The 18-second median and 37.6% sub-10-second rate are consistent with a semi-automated system or a human using a hotkey/quick-submit interface. Not fully automated (no sub-second bursts characteristic of pure bots) but not slow manual either. The pattern suggests a human trader watching the live match with a lightweight trading interface queued up.

Trading hours:

The wallet is active strictly 07:00-20:00 UTC, with zero fills outside that window. The single fill at 07:00 is an outlier (3 trades total in week 22). The bulk of activity runs 08:00-19:00 UTC, with a secondary peak at 12:00-18:00 UTC. This is fully consistent with European business hours - a trader in CET (UTC+1 or +2) watching CS2 matches broadcast in their evening.

Archetype: LIVE IN-PLAY CS2 SPECIALIST with semi-automated execution and active exit management.

Phase 2 - Core Strategy Identification

Both-sides participation: 83.5% (86 of 103 markets)

At first glance, 83.5% both-sides participation suggests market-making. The data refutes this interpretation completely. True market-makers show paired costs consistently below $1.00 and near-50% dominant-side win rates (the "no information" baseline). This trader's both-sides structure is an artifact of live-match position management - the trader builds a primary position on one side, then adds hedging or exploratory fills on the other side as match state evolves. The proof:

1. Mean paired cost: $1.083 (above $1.00 - no locked spread profit at the aggregate level)
2. Only 26.7% of markets have paired cost below $1.00 (a true MM books 80-100% sub-$1.00)
3. Dominant-side win rate jumps from 50% (1x) to 93% (3x+) - clear information gradient
4. Second-side lag median 799 seconds - markets are paired across 13+ minutes, not in simultaneous bracket entries

Classification: Directional in-play bettor with live-match read edge, using both-sides hedging as a position management tool, not as the primary edge source.

The trader is NOT:

• A market maker (paired cost above $1.00, sub-$1.00 rate only 26.7%)
• A pre-match bettor (fills start when matches are already underway, based on slug timing)
• A copy-trader (no consistent lag pattern; each match is a fresh unique event)
• A stale-price sniper (not targeting near-certainties - most buys are $0.50-$0.90)

---

Phase 3 - Dominance Ratio Analysis

This is the central finding of the report.

The 1.5-2.0x bucket underperforming the base rate (37.5% vs expected ~50%) is counterintuitive but explainable: these are markets where the trader built a large position, had conviction undermined mid-match by adverse round sequences, and added a large hedge leg, reducing the dominance ratio toward 2x. The apparent "low conviction" in these markets is actually a trail of failed high-conviction positions that got hedged down.

The 3.0x+ bucket (59 markets, 93.2% win rate) is the core edge. When the trader commits hard, they are almost never wrong. At $190,528 of BUY notional in the high-conviction filter, the +$14,880 P/L at +7.81% ROI is the entire profit engine.

---

Phase 4 - Entry Price Analysis

The capital allocation story: the largest single band by capital is $0.90-$1.00 ($63,779), closely followed by $0.80-$0.90 ($49,436) and $0.60-$0.70 ($49,084). This is a trader who predominantly buys favorites. The $0.90-$1.00 zone alone carries 20.6% of total BUY capital.

The ROI profile peaks in the $0.50-$0.60 band (+10.9%) and $0.40-$0.50 band (+8.6%). These are the mid-probability buys, and they correspond to the most interesting in-play moments: when a live match is evenly poised and the trader has a read on which team is about to seize control.

The sub-$0.10 band (-13% ROI) and sub-$0.30 bands (negative or near-zero ROI) are primarily the underdog/hedge legs - small exploratory positions or residual loses that come with the both-sides structure.

Sub-bucket note: The $0.10-$0.20 band's +12.1% ROI is anomalous for an underdog zone. Inspection of the CSV shows this is where the trader sometimes buys the underdog team heavily when they believe the favorite is being overpriced mid-match - the 85-share buy of JiJieHao at $0.20 in the June 18 trace is an example ($17.41 fill, Phantom won, so this lost). The positive aggregate ROI in this band despite losing outcomes on individual trades suggests some underdog calls did pay off.

---

Phase 5 - Category Breakdown

The entire book is classified as "Other" by the standard PR&R category framework (Counter-Strike 2 esports does not match the crypto/sports/politics keyword groups). There is no multi-category breakdown. The actual category is: CS2 esports, in-play.

For a more meaningful breakdown, the relevant dimension is tournament tier within CS2:

The Stake Ranked Ep 2 Playoffs contribution is dominant due to the magic vs NIP blowout win (+$8,760). Without that single market, the trading P/L drops from +$15,200 to +$6,440. The strategy is profitable across tournaments but has high variance per-match.

---

Phase 6 - Timing and Execution

Hourly P/L breakdown:

The 13:00-14:00 UTC window is the notable drag: -$1,943 and -$1,616 respectively on decent volume. This is when the trader is often mid-match, building positions in the early rounds before the match state has clarified enough to support the high-conviction calls. The 17:00-18:00 UTC window is the alpha zone: +$4,419 and +$4,017. By late afternoon European time, the matches the trader is watching have typically reached the decisive rounds where map winners become clearer.

Day-of-week breakdown:

Wednesday and Sunday are clearly the problematic days. Wednesday's 51.3% win rate is nearly the base rate for directional bets, suggesting the trader was in markets where their CS2 read was not sharp. Sunday's -27% ROI on only 33 trades (one or two bad matches at low volume) is likely a small-sample noise problem exacerbated by low-quality match selection on a low-activity day.

Saturday is the performance anchor: +$7,944 on 900 trades at +7.9% ROI. Many CS2 tournaments run their most competitive matches on Saturdays.

Second-side lag: Median 799 seconds (~13 minutes). This is the gap between the first-side and second-side entry in the same market. 13 minutes in live CS2 is about 2-4 rounds of play - consistent with the trader watching the match develop before deciding whether to hedge or add to the primary position.

---

Phase 7 - Filter Experiments

The high-conviction dom 2x+ filter is the critical finding. It captures 2,205 of 3,864 trades (57%) and retains +$14,880 of the +$15,200 total - meaning 97.9% of all trading P/L is in the high-conviction subset while only using 61.6% of the capital. The remaining 43.4% of capital (the low-conviction and hedge fills) contributes just +$320 of P/L.

The combined filter improves ROI to +8.58%, trading off absolute P/L (-$6,208 vs baseline) for better capital efficiency.

Full filter commentary is in the Filters tab.

---

Phase 8 - Rolling Window Consistency

Every rolling 15-day window in the observation period is positive. The 7-day windows show more volatility - one negative window around June 13 (-$851) corresponding to the NIP vs FaZe loss cluster and the Sunday underperformance.

Weekly summary:

Note: Week 24 (Jun 8-14) shows zero resolved P/L in the weekly data - the wallet was inactive that week, consistent with the 12-of-22 active-days figure. The strategy is episodic, not daily.

The cumulative P/L trajectory (account total including rewards) climbs from $5,126 on May 30 to $20,457 on June 20, with a notable plateau from June 7 through June 14 (the inactive week) and then an acceleration in the final week: +$3,143 on June 15, +$4,579 on June 16, then a small reversal and recovery through June 20.

---

Phase 9 - P/L Decomposition

The negative spread P/L (-$7,543) is decisive: this is not a spread-capture strategy. The combined paired cost above $1.00 in most dominance buckets means the trader is net paying for the two-sided position structure. The entire P/L comes from directional wins on the dominant leg, net of the hedge tax.

The $77,433 hedge tax is the cost of maintaining both-sides positions across 86 markets - all the losing non-dominant fills add up to over $77K of realized losses. The dominant-leg wins must overcome this drag, and they do: the dominant-side wins generate enough return to cover the hedge tax and still produce +$15,200 net.

---

Phase 10 - Strategy Specification

One-sentence summary: A live in-play CS2 esports trader who watches BO3 matches in real time, builds asymmetric two-layer positions (BO3 outright + individual map markets) when the live round score creates a mispricing, and sells aggressively when the market reprices toward fair value.

Edge source: Live CS2 match-state information advantage. The trader identifies when Polymarket's CLOB has not yet updated to reflect the round-score trajectory within a map, buys the team the rounds suggest is winning, and exits when the orderbook catches up. At 3x+ conviction, this approach produces 93.2% win rates across 59 markets.

What works best: 3x+ dominant-side positions (97.9% of P/L on 61.6% of capital). The $0.50-$0.60 mid-probability entry zone (+10.9% ROI). Hours 17:00-18:00 UTC (+$8,400 combined). Saturdays (+$7,944). Tier-1 and Tier-2 CS2 tournaments with consistent live broadcasts.

What drags: The hedge tax ($77,433). Hours 13:00-14:00 UTC (-$3,559 combined). Wednesdays (-$1,699). Sub-2x conviction markets. Sunday one-off trades.

Rebuild parameters: Bet only the dominant side when dominance ratio >= 3x. Avoid trading the 13:00-14:00 UTC hour unless conviction is extremely high. Weight Saturday matches and 17:00-18:00 UTC windows. Do not pursue both-sides spread capture on this book - it is a net negative. See Playbook for the full implementable spec.

The headline result

One filter does meaningful, measurable lift. The others are either neutral or destructive.

The high-conviction filter (dominance ratio >= 2x, dominant side only) retains +$14,880 of the $15,200 total P/L while cutting 43% of the capital base. That is the filter. Every other cut in the standard battery does less work.

The price-band filter is modestly additive on ROI (+5.83% vs +4.91%) but it cuts absolute P/L by $6,860 because too many of the profitable high-favorite buys ($0.70-$0.90) fall outside the $0.30-$0.70 window. Applied naively, it removes the trader's bread-and-butter favorite-side calls along with the genuinely bad underdog fills.

The category filter is identity (one category). The hour filter is modestly helpful but not transformative. The combined filter achieves the best ROI (+8.58%) by stacking the conviction gate with the hour exclusion, but at the cost of roughly 74% of absolute P/L.

Filter-by-filter commentary

1. Price band filter ($0.30-$0.70) MODEST LIFT ON ROI, DESTRUCTIVE ON ABSOLUTE P/L

The standard sweet-spot filter improves ROI from +4.91% to +5.83% but cuts absolute P/L from +$15,200 to +$8,340 - a loss of $6,860.

The mechanism is straightforward: the trader puts 43% of their BUY capital ($134K) into the $0.70-$1.00 range. That zone only returns +4.1% to +7.0% ROI (respectable but not exceptional), but because the capital base is so large, the absolute P/L contribution is substantial (+$6,579 combined from $0.70-$1.00). The filter discards all of that.

What the filter keeps: the $0.40-$0.60 zone, which genuinely has the best ROI (+10.9% and +8.6% respectively). If your goal is maximizing return on a smaller capital base, the $0.40-$0.60 window is the tightest alpha concentrate. But you sacrifice two-thirds of the book's absolute profit to get there.

Recommendation: Use the price band filter only if deploying limited capital and prioritizing ROI over absolute returns. Do not use it as a blanket rule - it discards profitable high-favorite calls that are load-bearing in this strategy.

2. High-conviction filter (dominance >= 2x, dominant side only) MEANINGFUL LIFT

This is the most important filter in the analysis. Applying the 2x+ dominance gate and keeping only the dominant leg:

• Retains 2,205 of 3,864 trades (57%)
• Retains $14,880 of $15,200 P/L (97.9%)
• Cuts $119K of capital (removes the low-conviction and hedge fills)
• Improves ROI from +4.91% to +7.81%

The non-dominant fills contribute virtually nothing to P/L (+$320 net) while consuming 43% of the capital. This is the mathematical case for a more focused, single-sided implementation.

The underlying reason this filter works so well: at 2x+ dominance, the dominant side wins 87%+ of the time in this dataset (77.8% at 2.0-3.0x and 93.2% at 3.0x+). These are genuine high-confidence reads. The sub-2x markets are where the trader was hedging or exploring, and those markets have a 37-50% dominant-side win rate - not worth the capital.

3. Category filter (Other only) NOT APPLICABLE

The entire book is "Other" by the standard PR&R taxonomy. CS2 esports does not match any of the keyword groups (NFL, NBA, NHL, MLB, UFC, Soccer, Crypto, Politics). The filter is identity-equivalent to baseline and contributes nothing analytically.

If the taxonomy were extended to include CS2 esports as its own category, the finding would be: the trader is already filtered to the one category where they have edge. No further category-level refinement is possible from the data.

4. Hour filter (exclude worst hours: 8, 11, 14, 19) MODEST LIFT

Excluding the four identified worst-performing hours (UTC 8, 11, 14, and 19) reduces the trade count by 1,077 (28%) and improves ROI from +4.91% to +6.23% at a cost of -$518 in absolute P/L.

Hour 8 (07:00-08:00 UTC window, 08 label) shows only 51.5% WR - the trader's earliest active hour, when they may not yet be fully engaged with the match or when the CS2 broadcast schedule has just started. Hour 14 (-$1,616 P/L) is the mid-session loss period discussed in the reverse-engineering analysis. Hours 11 and 19 have moderate negative contributions.

The hour filter's modest lift (+$1.32% ROI improvement) does not justify the operational complexity of implementing a per-hour gate alongside the dominance gate. The dominance filter already does most of the heavy lifting. If you implement both, you get +8.58% ROI on a much smaller capital base - high efficiency, low absolute scale.

Recommendation: The hour filter is a secondary refinement. The dominance filter is the primary one. Implement the dominance filter first; add the hour filter if you want to further optimize ROI at the cost of volume.

5. Combined filter (dom 2x+ + skip hours 8, 11, 14, 19) MEANINGFUL LIFT ON ROI, LOW ABSOLUTE SCALE

Best ROI in the battery at +8.58%, achieved on 997 trades and $104,835 of capital. The combined filter is essentially "high-conviction bets during the trader's peak performance hours."

At $104,835 of capital and +8.58% ROI, the expected trading P/L is ~$8,990 over a 22-day window - an annualized rate that is strong but not extraordinary. The absolute P/L shrinks from +$15,200 to +$8,992 because the volume contraction overwhelms the ROI improvement.

For a replicator with limited capital who cannot deploy $309K across 12 days of CS2 matches, the combined filter tells you exactly which trades to pick: 3x+ conviction during 09:00-13:00 UTC and 15:00-18:00 UTC.

6. Underdog blocking filter EQUIVALENT TO HIGH-CONVICTION FILTER

The high-conviction filter (dominant side only, 2x+ dominance) already effectively blocks the underdog positions, since "dominant side" by definition excludes the smaller-allocation leg. A separate "underdog blocking" rule would be redundant with the dominance gate. The combined effect of "never bet the non-dominant side in a 2x+ dominated market" is already captured in the filter output.

The one case where underdog blocking adds incremental value is in the 1.0-1.5x markets (10 total, 50% win rate): here, neither side is strongly dominant, and both fills are roughly equivalent in size. In these 10 markets, the trader would benefit from simply not trading at all rather than trying to pick a "dominant" side with a 50/50 read.

---

Bottom line for replication

Three concrete recommendations:

1. Apply the dominance gate at 2x. It retains 97.9% of the P/L on 61.6% of the capital. The gain in ROI (+2.9 percentage points) plus the freed capital is the single most impactful operational change.

1. Do not bet the non-dominant side. The hedge fills generate $320 of net P/L on $119K of capital over 22 days. That is near-zero expected return. The structural cost of carrying both-sides positions is the $77,433 hedge tax embedded in the P/L decomposition. A single-sided implementation would eliminate that drag.

1. Be selective about match entry hours. The 17:00-18:00 UTC window generates +$8,436 of P/L (55% of the total) on only 1,191 trades (31% of volume). Trading is most profitable in the second half of European business hours. If you can only be active during one window, make it 15:00-19:00 UTC.

The single most useful filter you can apply to this strategy is the dominance gate. Everything else is incremental. See the Playbook tab for the implementable specification.

One-paragraph operator brief

Watch live CS2 matches on Polymarket's CLOB. When the round score within a map creates a clear probability gap - a team is winning rounds at a rate the orderbook has not yet fully priced - build a dominant-side position on that team across both the map-level market and the BO3 outright. Commit only when you would allocate at least 3x more capital to your primary call than any hedge leg. Sell aggressively when the orderbook reprices toward fair value after the next round or series of rounds. Hold residual to resolution. Active only during European business hours (08:00-20:00 UTC). Focus on 15:00-19:00 UTC for highest-edge windows. Never trade without a strong live-match read. Expect approximately +5-8% trading ROI on capital deployed, with the higher end achievable by filtering to 3x+ conviction moments only.

1. Market selection

The two-layer approach is structural, not optional. Trading both the map-level market and the BO3 outright simultaneously on the same event gives you two orderbooks to express a single live-match view. When map pricing and match pricing are momentarily inconsistent (the map has clarified but the BO3 outright has not re-priced yet), both layers generate positive EV. The reference wallet shows 2.86 markets per event - this is the operational target.

Tournament selection guidance: the reference book spans Stake Ranked and NODWIN Clutch Series tournaments. Both are broadcast live with round-by-round score updates. The key criterion is that the Polymarket orderbook is sufficiently liquid and that the broadcast delay between actual round completion and your awareness of it is minimized.

2. Entry logic

The entry signal is a live round-score read: your assessed probability of a team winning the current map diverges from the CLOB mid-price by a meaningful threshold.

def should_enter(market, your_prob, clob_mid):
    # Only CS2 markets
    if not is_cs2_market(market):              return None

    # Only in-play (series started)
    if not market.is_live():                   return None

    # Only during active trading hours
    if utc_hour(now()) not in range(8, 20):    return None

    # Gap threshold - your read must diverge enough from market price
    gap = your_prob - clob_mid
    if abs(gap) < 0.08:                        return None  # need at least 8% mispricing

    # Conviction pre-check - only enter if you'd allocate 3x+ to this side
    if not can_commit_3x_ratio(your_prob):     return None

    return ("buy_favorite" if your_prob > clob_mid else "buy_underdog")

Critical: do not enter at sub-2x allocation ratios. The data shows that 1.5-2x dominance markets have a 37.5% win rate - worse than a coin flip. These are markets where the trader either does not have a clear read or has a bad read and adds a large hedge. If you cannot allocate 3x to your primary call, skip the market.

The entry on the underdog side is valid but only in specific circumstances: when the live round score shows the underdog winning rounds faster than their market price reflects, and your conviction is sufficient for a 3x+ allocation on that underdog. The CSV shows several profitable underdog calls (e.g. JiJieHao at $0.35-$0.40 before Phantom repriced lower). Do not reflexively avoid underdog entries - but hold them to the same 3x+ conviction standard.

---

3. Exit logic

Active exit management is part of the edge. The reference wallet does not hold all positions to resolution. The June 18 JiJieHao vs Phantom trace shows repeated buy-sell cycles within a single match, with large position dumps as the orderbook reprices in the trader's direction.

def manage_position(position, live_market_mid):
    # Phase 1: post staged asks above current mid
    current_fair = your_estimated_prob(position.market)
    
    # If market has repriced toward your view, start selling
    profit_per_share = live_market_mid - position.avg_entry_price
    
    if profit_per_share > 0.10:  # 10 cent per share gain threshold
        # Sell ~50% of position into the first rally
        sell_tranche(position, shares=position.shares * 0.5,
                     price=live_market_mid - 0.01)
    
    if profit_per_share > 0.20:  # 20 cent gain threshold
        # Sell remaining position (hold small residual for resolution)
        sell_tranche(position, shares=position.shares * 0.45,
                     price=live_market_mid - 0.01)
    
    # Phase 2: hold residual to resolution
    # Unsold shares (~5-10% of original) settle at $1.00 (win) or $0.00 (loss)

Why no hard stop loss: the reference wallet shows essentially no explicit stop behavior - positions that go against the trader typically fall to near-zero and resolve at $0.00. Given the 93.2% win rate at 3x+, the expected value calculation still favors holding: paying for a stop loss would give up wins that are genuinely in the high-probability zone. The occasional -$2,639 (NIP vs FaZe BO3) is the price of conviction-based betting without stops.

4. Sizing model

The reference book uses a graduated sizing approach: small exploratory fills early in the match, larger anchor clips as conviction solidifies, and then aggressive exits as the market confirms the view.

The reference wallet's $80.93 mean fill masks the bimodal distribution: many fills in the $10-$100 range for position exploration, and large anchor fills at $200-$9,000 for peak-conviction moments.

The sizing rule that matters most: when you would not allocate 3x on the primary side, keep the total position size small (exploratory zone, $10-$50 per clip). When you cross the 3x threshold and the live match state clearly supports your view, scale up. The reference book's top-5% capital concentration (44.8% of capital in the top 5% of trades) shows this is being done correctly.

5. Bankroll math

Reference window performance (22 calendar days, 12 active):
  BUY notional deployed:      $309,516
  Resolved trading P/L:       +$15,200
  Liquidity rewards:          +$5,257
  Account total:              +$20,457

Annualized trading ROI (trading P/L only):
  22 days → 4.91% ROI on $309K
  Monthly equivalent: ~6.7% on capital deployed (22/30 day adjustment)
  Annual equivalent: ~80% on capital deployed (assumes consistent activity)

Working capital requirement:
  Peak concurrent exposure: ~$50K-$100K (multiple live matches simultaneously)
  Capital cycles within a single match: ~2-4 hours
  Typical match duration (BO3): 2-4 hours
  Capital recycled same day in most cases

The liquidity rewards (+$5,257) represent 25.7% of the account total. This is not a trivial add-on. For a wallet actively trading both sides of CS2 markets with high turnover ($592K gross), Polymarket's liquidity rewards are a meaningful supplement. Factor this into bankroll calculations: the actual return on capital is +20,457/309,516 = +6.6% account ROI in 22 days including rewards.

6. Scheduling and timing

Day-of-week: Trade Mon, Tue, Thu, Sat at full weight. Avoid Wed (historically -4.8% ROI) and skip Sun unless a marquee match is scheduled (the -27% Sunday ROI is driven by only 33 trades - one bad match).

Saturday is the highest-absolute-P/L day (+$7,944) due to major CS2 tournament scheduling. Do not miss Saturdays.

---

7. The both-sides question

The reference wallet uses both-sides positioning in 83.5% of markets, but the P/L decomposition shows spread P/L of -$7,543 (negative) and a hedge tax of $77,433. The both-sides structure is a net cost, not a profit mechanism.

The case for single-sided implementation:

Dropping the non-dominant fills entirely would save capital and eliminate the spread drag. The expected trade-off is slightly lower absolute P/L (you miss the occasional underdog wins that the hedge captures) but materially better ROI on capital deployed.

The case for keeping the hedge: the reference trader may use the non-dominant fills for live-match price discovery - small buys on the "wrong" side to probe the orderbook depth or test the market's reaction to a round result. This information has value beyond its direct P/L. A pure single-sided implementation loses that data feed.

Recommendation for replicators: start single-sided (dominant leg only, 2x+ conviction gate). Add hedging only after you understand the live-match dynamics well enough to use the hedge fills for price discovery rather than protection.

---

8. Risk profile

The strategy is bounded-loss per market but not bounded-loss per series. A three-match run of bad CS2 reads (all at 3x+ conviction) could produce -$7,500 to -$15,000 on a $25K bankroll. The rolling 7-day volatility range in the reference data is -$851 to +$7,215 - manageable at the reference scale but jarring for undercapitalized replicators.

---

9. Operational requirements

The central operational requirement is live CS2 knowledge, not software. You need to know:

• How to read a CS2 round score for momentum (not just current score but round economy, side advantage, etc.)
• Which maps favor which teams in the current meta
• How map-score translates to BO3 probability at each state
• Which tournament formats affect team preparation and motivation

Without this domain knowledge, the 93.2% win rate at 3x+ conviction is unreproducible. A bot watching the Polymarket orderbook alone has no advantage - the edge is in the CS2 knowledge that allows you to identify the mispricing before the orderbook corrects.

---

10. What this playbook deliberately does NOT include

• No spread-capture rule. The both-sides structure in this wallet has a -$7,543 spread P/L. Do not replicate it as a spread-capture strategy - it is not one.
• No fixed entry price rule. This is not a "buy favorites below $0.80" strategy. The entry price is whatever the orderbook offers when the live match signal fires. Pinning a price would cause you to miss the best setups.
• No pre-match bets. The edge is in the live round-score read. Pre-match bets on CS2 team strength do not benefit from the same information advantage. The reference wallet appears to enter all positions after the match starts.
• No other esports. The reference wallet is CS2-only. Valorant, Dota 2, LoL, and other titles have different team structures, round economies, and match formats. Your CS2 knowledge does not automatically transfer.
• No sizing-by-ELO or team ranking. The hedge tax analysis shows that the trader's losses come from matches where team ranking suggested a clear favorite (NIP vs FaZe) but the live match state said otherwise. Team ELO is a prior; the live round score is the posterior. Always update.
• No revenge trading on losing matches. The NIP vs FaZe blowup was concentrated: -$3,594 across both the Map 1 and BO3 markets. Going back into the same match or next match with increased size to "make it back" is the fastest way to amplify the loss. The reference wallet does not show evidence of this behavior, but it is the natural trap when conviction-based strategies hit a cluster of losses.

The whole strategy is: know CS2, watch the match, bet what you see at 3x+ conviction, sell into the move, and walk away from matches where you do not have a clear read. Simpler to describe than to execute, because the discipline of walking away from sub-3x conviction markets is the hardest part of the implementation.
