Market Probe scans the public sell orders across the major trade hubs (Jita, Amarr, Dodixie, Rens, Hek) and finds items listed significantly below the lowest competing price at that station. These are commonly called mistake orders — fat-finger prices, wrong decimal places, or items listed in the wrong station. The goal is to buy them before anyone else does and relist at market price.

Each scan pulls all sell orders from each selected hub via the EVE ESI public API. For every item with multiple sell orders at a station, it compares the cheapest listing against the next cheapest. If the gap is large enough to be profitable after broker fees and sales tax, it shows up as a deal. Scans run automatically on a timer (default 10 minutes) or manually with Scan Now.

• Item — the item name. Click the copy icon to copy it, or the market icon to open it in-game.
• Hub — which trade hub the deal was found at.
• Buy At — the mistake price you would pay.
• Relist At — suggested relist price (one tick below the next lowest sell order).
• Profit — ISK profit after broker fee and sales tax.
• Profit % — profit as a percentage of the buy price (ROI).
• ISK Required — total capital needed to buy the available quantity.
• Volume — how many units are listed at the mistake price.

• ISK Floor / % Floor — minimum profit in ISK and/or minimum ROI % a deal must meet to show. Use AND to require both, OR to require either.
• Min Volume — hides deals where fewer than X units are available.
• Broker Fee / Sales Tax — set these to match your character's skills and standings. Defaults are 3.375% broker fee and 1.5% tax.
• Rescan Interval — how often to auto-scan. Lower intervals mean fresher data but more ESI calls.
• Categories & Groups — filter results to specific item categories or groups. Useful for focusing on items you actually trade.
• Hubs — toggle which trade hubs to include in the scan.

• Does not scan for regional arbitrage (buying in one region, selling in another) — use Trade Run for that.
• Does not place buy orders or interact with the market automatically — you still buy manually in-game.
• Does not guarantee a deal is still available by the time you open the game — mistake orders are fast moving.
• Does not account for market depth — if there are 10,000 units at the mistake price, relisting all of them may move the market.

The Last 20 Scans sparkline shows the total deal value found per scan over your last 20 scans. Use it to spot patterns — if the line is trending down, either the market is getting more efficient or your filters are too tight. The Last Scan value shows the total opportunity from the most recent scan. Hit ✕ to clear the history and start fresh.
