Drawdown Circuit-Breaker Governor

This is a safety governor, not a trade signal. A supervisory layer watches your rolling peak-to-trough equity and automatically shrinks the whole book in tiers (for example, halve gross at -8%, stop all new entries at -15%), then locks out re-entry until a cool-down passes or equity recovers. The purpose is pure capital preservation: mechanically capping catastrophic losses when a model misfires or the market regime breaks.

Where this applies

Markets on Polymarket where drawdown circuit-breaker governor is the natural play:

Will BTC close above $130k on December 31, 2026? (high-volatility crypto exposure)
Will SOL be above $300 on September 30, 2026? (jumpy tail-risk market)
Will the named candidate win a contested 2026 Senate race? (binary event-risk position)
