Position-Graded Profit Ratchet

This strategy trades Kalshi's KXBTC15M Bitcoin market, checking conditions every 10 seconds with a maximum position of 500 contracts and allowed prices between 0.01 and 0.99. Rules run top to bottom and only the first match acts. Rule 1 skips when position size is at least 500. Rules 2 through 7 exit on per-fill profit or loss thresholds that vary by position size: at 100 or fewer contracts it sells everything when unrealized profit exceeds 12 or loss falls below -25; at 101 to 300 contracts it exits when profit exceeds 18 or loss falls below -40; at 301 or more it exits when profit exceeds 50 or loss falls below -60, with the profit rules also requiring price between 0.10 and 0.90. Rules 8 through 15 only enter when position size is 249 or fewer, each buying 250 contracts. Four momentum pairs buy yes or no depending on whether Bitcoin's price is above or below its one-hour VWAP and 12-minute EMA, or simply on 5-minute change and 1-minute velocity, with price bands of 0.35 to 0.65 or 0.20 to 0.80 and spread capped at 0.015. Two near-expiry pairs act within 5 minutes of expiry using price bands of 0.40 to 0.60 or the extremes of 0.88 and 0.12 with wider 0.03 spreads.
