⏲ Buy Limit Timer

How GE Buy Limits Work

Every item on the Grand Exchange has a buy limit — the maximum quantity you can purchase within a 4-hour rolling window. Limits range from 2 for ultra-rare items like the Twisted Bow to 25,000 for commonly traded runes. Your personal timer starts the moment your first buy offer fills for that item, and it resets exactly 4 hours later regardless of how many you bought.

Each GE slot tracks its own timer independently, so buying Rune Arrows doesn't affect your limit on Dragon Bones. You can also spread purchases across multiple accounts if you need to exceed the limit for a single session. Understanding buy limits is critical for flipping because your maximum profit per cycle is capped at margin × buy limit — items with higher limits allow faster capital turnover.

Use the timer above to track when your limits reset. For items with low buy limits, plan your flipping sessions around the 4-hour cycle to maximise throughput. The Flip Finder shows current margins alongside buy limits so you can estimate profit per limit cycle, and the GE Tax Calculator helps you factor in the 2% tax on every sale.

Strategy Tips for Buy Limit Management

Use multi-slot strategies for high-volume flipping. With 8 GE slots, you can flip 8 different items simultaneously, staggering their buy limit resets throughout a session. When one item's limit resets, immediately place a new buy offer. This keeps all your capital working at all times and maximises total GP/hr across all slots.

Stagger your items by starting buy offers at different times rather than all at once. This creates a rolling reset schedule where some items become available to re-buy every 30-60 minutes instead of all resetting simultaneously in 4 hours. The timer above helps you track each item's individual reset window.

Common Mistakes to Avoid

1. Not starting the timer on first purchase — Your 4-hour window begins when your first buy offer fills, not when you place it. Start tracking immediately after the first fill to know exactly when you can buy again.
2. Confusing buy limit with sell limit — There is no sell limit on the GE. You can sell unlimited quantities of any item. The buy limit only restricts purchasing. Plan your sales independently of buy limit timing.
3. Not planning around 4-hour windows — If you are flipping during a limited play session, prioritise items whose buy limits will reset before your session ends. There is no point buying items you cannot re-buy and flip within your available time.
