#ArbitrageTradingStrategy

Arbitrage trading is a strategy that aims to profit from price discrepancies of the same asset in different markets, by simultaneously buying the asset at a lower price in one market and selling it at a higher price in another. This strategy seeks to exploit market inefficiencies and is generally considered low-risk because the buy and sell transactions occur almost simultaneously, thus minimizing exposure to price changes.

I would have assumed that as soon as the fastest trader (I.e. a big trading firm with amazing network connections and highly optimised trading bots) spots an arbitrage opportunity and trades at big volumes between two markets the supply and demand change at each end would just close the price gap. Nevertheless there seem to be (semi?) reputable sources suggesting it’s possible to perform successful arbitrage using a laptop on home broadband with a bit of web3.js. Is it all just snake oil sales or is there something I’m missing that means you won’t always be outpaced by big teams of engineers?
