F Dark crab — fishing-supply spread flip killed
kill signal sustained over 3 consecutive evaluations (failing: floor_ok)
Dark crab is a fishing/processing intermediate bought by PvM food-stacking mains (700+ eaten per COX run). Cooked fish suppliers dump stock in batches; combat buyers accept higher instabuy offers to refill. The 21-day daily band is 1,264-1,414, current 1,353-1,412 (top quartile) - the upward drift is modest (~1% over 7 days) and the 24h 5m history shows the 30-50 gp spread re-printing continuously. Vol24h ~862k units vs per-cycle buy limit 10,000 - well within the 15% participation assumption.
Entry: place buy offer at 1353 gp; refresh if not filled in 5 min, cancel if ask lifts above 1380
Exit: place sell offer at 1412 gp; refresh if not filled in 5 min, cancel if bid falls below 1380
Kill switch: Live margin below 15 gp for 4 consecutive hours; OR 21-day close band breaks above 1,450 (band top violation - runaway trend); OR vol24h drops below 400k for two sweeps.
