BTC 15M Price Bands

This strategy trades Kalshi's most liquid KXBTC15M market, checking conditions every 30 seconds and applying rules top to bottom, with the first match ending that tick. Rule 1 sells all held position when unrealized profit/loss is at or below -25. Rule 2 buys 50 YES contracts only if there is no position or resting order, fewer than 3 portfolio positions, 120 to 300 seconds to expiry, the YES ask is between 0.35 and 0.80, spread is 0.03 or less, Bitcoin's 5-minute change is at least 0.0005, Bitcoin's 1-minute velocity is above zero, and Ethereum's 5-minute change is at least -0.0005. Rule 3 buys 50 NO contracts under the same position, order, portfolio, expiry, and spread conditions, but requires the NO ask between 0.35 and 0.80, Bitcoin's 5-minute change at or below -0.0005, Bitcoin velocity below zero, and Ethereum's 5-minute change at or below 0.0005. The 50-contract position limit, up to 3 portfolio positions, and price bounds of 0.44 to 0.66 also apply. Entries are capped at one per market and $50 notional per market, with spent budget not released by later sells; the $25 max-loss threshold can halt and liquidate only this strategy's attributed Kalshi inventory.
