Find your next trade.

Place a patient buy near the reported instant-sell price and a patient sell near the instant-buy price. Net profit subtracts a 2% RS3 sales tax, rounded down per item, without an OSRS tax cap. Batch size uses your budget, the published buying limit (when known), and at most 1% of observed hourly volume. This is a planning ceiling, not available stock or a promise of filled offers. Unknown limits and missing volumes are clearly labeled.
