Position-Graded Profit Ratchet

On Kalshi's KXBTC15M market, this trades BTC-USD 15-minute contracts, checking every 10 seconds. Rules run top to bottom; the first match fires. Over 500 contracts (limit 500), rule 1 skips. Exits sell all: rules 2-4 take profit at unrealized PnL above 12 (size ≤100), 18 (101-300), or 50 (≥301), the first two also needing price 0.10-0.90; rules 5-7 stop out below -25 (≤100), -40 (101-300), or -60 (≥301). Entries, all requiring size ≤250 and buying 250 contracts, are: rule 8 buy yes when BTC price is above both its 1h VWAP and 12-period 1m EMA, 5m change above 0.001, 1m velocity positive, price 0.35-0.65, spread ≤0.015; rule 9 the mirrored buy no. Rule 10/11: buy yes when 5m change above 0.0015 with positive velocity, or buy no below -0.0015, price 0.20-0.80, spread ≤0.015. Rules 12/13, within 5 minutes of expiry: price 0.40-0.60, 5m change and velocity same direction, BTC above VWAP and 12-EMA above 20-SMA for yes (mirrored for no), spread ≤0.015. Rules 14/15, also within 5 minutes: buy yes if price ≥0.88, spread ≤0.03, BTC at/above its 15m high and velocity positive; buy no if price ≤0.12, spread ≤0.03, BTC at/below its 15m low and velocity negative.
