What is the difference between REST API and WebSocket API for crypto arbitrage?

REST API sends individual requests to an exchange and waits for a response — suitable for cross-exchange hedge arbitrage where execution windows are seconds to minutes. WebSocket API maintains a persistent connection with real-time streaming data — essential for latency arbitrage where price updates arrive every millisecond and execution windows are 100–500ms. VIP Crypto Arbitrage uses REST API (simpler, sufficient for hedge strategies). SharpTrader uses WebSocket API (required for latency arbitrage on crypto).

How does a crypto arbitrage bot work?

A crypto arbitrage bot connects to multiple cryptocurrency exchanges via API, monitors prices in real time, detects price discrepancies above a configured threshold, and executes buy and sell orders automatically. For cross-exchange arbitrage, it simultaneously buys on the cheaper exchange and sells on the more expensive one. For latency arbitrage, it detects when one exchange's price lags a fast reference feed and trades the gap before the slow exchange updates. The bot handles all detection, execution, and position management automatically.

REST API vs WebSocket API — why it matters for crypto arbitrage

The most important technical difference between the two bots is their API connection type. This directly determines which strategies are viable and how fast execution can be:

REST

REST API — request/response (VIP Crypto Arbitrage)REST API sends individual requests to the exchange and waits for a response. Each price check, each order placement is a separate HTTP request. Response times: typically 50–500ms per request. This is sufficient for cross-exchange hedge arbitrage where price gaps persist for seconds to minutes. Not suitable for latency arbitrage where windows are 100–500ms and require streaming data.

WSS

WebSocket API — persistent real-time stream (SharpTrader)WebSocket maintains a persistent connection to the exchange’s price feed. Price updates stream in real time — every tick, every millisecond. This is essential for latency arbitrage where you need to detect a price gap and execute within 100–500ms of a fast source update. SharpTrader connects to 40+ crypto exchanges via WebSocket for real-time tick data.

What is the difference between REST API and WebSocket for crypto arbitrage?

REST API sends individual requests and waits for responses — adequate for cross-exchange hedge arbitrage where gaps persist seconds to minutes. WebSocket maintains persistent real-time streaming — essential for latency arbitrage where you need tick-by-tick price data and must execute within 100–500ms of a fast source update. VIP Crypto uses REST; SharpTrader uses WebSocket.

Can I use these bots on Binance and Bybit?

Yes. Both VIP Crypto Arbitrage and SharpTrader support Binance (Spot and USDT Futures) and Bybit (Spot and USDT Perpetual). These are the two highest-liquidity exchanges and the most popular starting point for cross-exchange crypto arbitrage. The free scanner also covers both exchanges.

Do crypto exchanges allow arbitrage bots?

Yes — most major cryptocurrency exchanges permit automated arbitrage trading and do not restrict it in their terms of service. Unlike retail forex brokers, crypto exchanges earn fees from arbitrage volume and generally welcome it. This is a key advantage of crypto arbitrage over forex arbitrage.
