Crypto arbitrage guide
How the scanner and the trading terminal work, end to end: which spread types exist, how to read the table and the order book, and how a trigger opens and closes a delta-neutral position for you.
User Guide
← BackWhat is the scanner
The scanner monitors price discrepancies (spreads) in real time across 12 exchanges for all traded pairs. When the price of the same asset differs between exchanges — that is an arbitrage opportunity: buy cheaper on one exchange and sell higher on another.
Data arrives via WebSocket without page reloads. The Live (green) indicator in the top-right confirms an active connection. On disconnect — automatic reconnection.
Spread types (tabs)
AllAll spread types at once — for a general market overview.
Long-Short (FF — Futures/Futures)Compares futures prices between two exchanges. You buy a futures contract where the price is lower (Long) and sell where it is higher (Short). Positions are opened simultaneously on both exchanges.
Spot-Short (SF — Spot/Futures)Buy the asset on spot at one exchange, sell a futures contract on another. Delta-neutral position: profit = spread + accumulated funding.
Funding RateDifference in funding rates between exchanges. Exchanges pay the rate every 8 hours. If rates diverge — you can earn on the difference by holding the position.
