How to flip Nihil shard in OSRS

Flipping Nihil shard on the Old School RuneScape Grand Exchange currently makes about 23 gp profit per item after the 2% GE tax: buy near 2,860 gp (the instant-sell price) and re-list near 2,941 gp (the instant-buy price).

• Buy at (instant-sell): 2,860 gp
• Sell at (instant-buy): 2,941 gp
• Margin after 2% tax: 23 gp (0.80% ROI)
• Buy limit per 4 hours: 30,000
• 24h volume: 67,295 (very liquid)
• Max profit per limit cycle: 690,000 gp on 85,800,000 gp of capital

The flip, step by step

1. Place a buy offer at or just above 2,860 gp (the current instant-sell price).
2. Wait for the fill. Nihil shard is very liquid right now, so offers usually fill within minutes to a quarter hour.
3. Re-list at or just below 2,941 gp (the current instant-buy price).
4. The GE takes 58 gp tax (2%) per item when it sells, leaving 23 gp profit each.
5. Repeat up to the buy limit (30,000 per 4 hours), a full cycle is 690,000 gp on 85,800,000 gp of capital.

Margins move constantly. Re-check the live Nihil shard numbers and price chart on GrandExchange.com right before committing.
