Position-Graded Profit Ratchet

This Kalshi strategy trades the KXBTC15M series, evaluating every 10 seconds against BTC-USD data refreshed every 5 seconds, with a 60-contract position limit and YES prices bounded between 0.01 and 0.99. Rules run top to bottom and the first match ends the tick: Rule 1 skips when position size is at least 60. Rules 2 through 4 sell everything on profit gates tied to size bands (up to 15 contracts with unrealized profit above 6 and price between 0.10 and 0.90; 18 to 36 contracts with profit above 9 and the same price band; 39 or more with profit above 15). Rules 5 through 7 sell everything on stop gates by the same size bands (down more than 9, 15, and 21 respectively). Rules 8 through 13 buy 30 contracts only when size is 27 or less: trend entries versus VWAP and the 12-period EMA with price 0.35 to 0.65 and spread at most 0.015; acceleration entries on 5-minute change and velocity with price 0.20 to 0.80; and final-5-minutes entries with price 0.40 to 0.60. Rules 14 and 15 buy 30 contracts in the last 5 minutes when price is at least 0.88 or at most 0.12, spread at most 0.03, and price sits at the 15-minute high or low with matching velocity.
