BTC ladder variants

On Kalshi's most liquid KXBTC15M market, this strategy checks conditions every 10 seconds and caps total position at 5 contracts, with prices allowed between 0.05 and 0.99. Rules are checked in order and the first match fires. The first two rules sell an existing YES or NO position if its best bid falls to 0.35 or below. Rules 3 and 4 sell a YES position when spot is below the strike, or a NO position when spot is above it. Rules 5 and 6 sell a position when time to expiry is between 2 and 15 minutes and its best bid is at least 0.995. Rules 7 through 14 buy 5 contracts of YES or NO at progressively tighter expiry windows: within 4 minutes when spot is at least 45 points above (or below) the strike, within 2 minutes at 30 points, within 1 minute at 22.5 points, and within 30 seconds at 15 points, each requiring direction agreement across the 5-minute, 15-minute, and 1-hour changes, the 1-minute velocity, and the EMA relative to strike. Rules 15 and 16 buy 5 contracts within 25 seconds when the spread is at most 0.03 and the relevant ask is between 0.9 and 0.99. All entries require no open orders and use immediate-or-cancel execution.
