The flip, step by step

1. Place a buy offer at or just above 3,000 gp (the current instant-sell price).
2. Wait for the fill. Nihil dust is very liquid right now, so offers usually fill within minutes to a quarter hour.
3. Re-list at or just below 3,019 gp (the current instant-buy price).
4. The GE takes 60 gp tax (2%) per item when it sells, leaving -41 gp profit each.
5. Repeat up to the buy limit (11,000 per 4 hours), a full cycle is -451,000 gp on 33,000,000 gp of capital.
