F Sapphire dragon bolts (e) — PvM ranged ammo patient flip vetoed
vetoed at ship time: claimed per_cycle_gp 1045000 exceeds 2x the live recomputation 180405 (margin 95 x 1899 fillable units)
Mid-tier dragon-bolt ammunition has a structural 90-110gp post-tax spread because broad-bolt-head fletchers (Crafting) and bolt-tip crafters supply the e-version continuously, while mid-game ranged users (slayer, demonbane, dragon hunters) buy at the offer wall without placing patient bids. Patient flipper earns the 2% GE tax + spread, 6x/day at the 11k buy limit. 7d hourly obs show the spread present in essentially every bucket — not a one-print artifact.
Entry: Place buy offers at 2831 gp; refresh every 30 min if not filled.
Exit: Place sell offers at 2985 gp; refresh every 30 min.
Kill switch: Live quote low falling below 2700 for any 5-min block (kill_price breach); OR persistent 24h horizon where margin <40gp after tax; OR a Jagex PvM ranged rebalance announced.
