F Dragon nails — 60gp block-average spread with budget-constrained sizing killed
kill signal sustained over 3 consecutive evaluations (failing: entry_reachable, floor_ok)
Construction commodity used by high-level players for fancy furniture; mid-volume but persistent 2-sided flow. 30d daily close band 12400–14100 with the current 13350 sitting in the middle of that range. The post-tax margin of 60gp on a 13000 buy_limit × 13170 low requires 171M capital, so the size is capped at 3795 units (the budget-feasible level). At that size the cycle pays 60 × 3795 = 227,700 gp — clears the 200k floor with a small cushion. Vol5m 956 comfortably fills 3795 units in one 4h window.
Entry: Place buy offer at 13170 (low); place sell offer at 13230 (high).
Exit: Cancel unfilled side if margin collapses below 30gp for two consecutive evaluations.
Kill switch: Margin collapses below 30gp AND daily close drops below 12500.
