Position-Graded Profit Ratchet

On Kalshi's KXBTC15M series, this strategy checks every 10 seconds, caps positions at 100 contracts, and trades only between prices 0.01 and 0.99. Rules run top to bottom and the first match fires alone. Rule 1 skips at 100 contracts. Exits: with 20 or fewer contracts, sell all if unrealized profit exceeds 12 and price sits between 0.10 and 0.90, or if loss exceeds 25. With 21 to 60 contracts, sell all if profit exceeds 18 and price is 0.10–0.90, or loss exceeds 40. With 61 or more, sell all if profit exceeds 50 or loss exceeds 60. Entries require 50 or fewer contracts and buy 50 contracts. Rules 8 and 9 buy yes or no when price sits above or below both BTC VWAP and 12-period EMA, 5-minute change exceeds ±0.001, velocity is directional, price is 0.35–0.65, and spread is at most 0.015. Rules 10 and 11 use ±0.0015 change and price 0.20–0.80. Rules 12 and 13 require 5 minutes or less to expiry, price 0.40–0.60, directional change, velocity, VWAP, and EMA versus SMA alignment. Rules 14 and 15 require 5 minutes or less, price at least 0.88 or at most 0.12, spread at most 0.03, price at 15-minute high or low, and directional velocity.
