F Ruby dragon bolts — persistent 60gp spread on a high-volume PvM ranged commodity killed
kill signal sustained over 3 consecutive evaluations (failing: margin_alive, entry_reachable, floor_ok)
Ruby dragon bolts (item 21967) trade in a tight 2800-2900gp band with a persistent 25-65gp post-tax margin between fresh buy and sell legs; 480k vol/24h and 12k vol/5m make the 11,000-unit buy limit fillable. The mechanism is the standard patient-flipper edge: smithing/imbueing sources dump to impatient buyers at a thin spread that re-appears every hour because no one places patient offers.
Entry: Place buy offers at 2769gp or lower; refresh every 4h.
Exit: Place sell offers at 2890gp; accept fills within 12h of buy fill.
Kill switch: Block-avg spread falls below 15gp for 3 consecutive 1h samples; OR live price drifts below 2750gp (below 30d low close); OR live margin drops below 40gp with both legs fresh.
