Momentum VWAP Tiered Exit

Trades Kalshi's KXBTC15M series, evaluating every 10 seconds with a 50-contract limit and YES prices allowed from 0.01 to 0.99. Rules run top to bottom; only the first match fires per tick. Rule 1 skips when position size exceeds 51. Rules 2-4 sell all on profit: sizes up to 10 need profit above 1.2 with price between 0.10 and 0.90; sizes 11-30 need above 1.8 at that price band; sizes 31+ need above 5. Rules 5-7 sell all on loss: sizes up to 10 below -4; 11-30 below -6; 31+ below -15. Rules 8-15 buy size 10 only when time to expiry is 7 minutes or less: rule 8 buys YES on BTC price above both VWAP and EMA, change above 0.001, positive velocity, price 0.35-0.65, spread at most 0.015; rule 9 buys NO on the mirrored negatives. Rule 10 buys YES on change above 0.0015 and positive velocity, price 0.20-0.80, spread at most 0.015; rule 11 mirrors for NO. Rule 12 buys YES when price is 0.40-0.60, change and velocity positive, BTC above VWAP, EMA above SMA, spread at most 0.015; rule 13 mirrors for NO. Rule 14 buys YES at price 0.88 or higher, spread at most 0.03, 15-minute high and BTC price both above 15; rule 15 buys NO at price 0.12 or lower with low above 15 and price above 15.
