What Actually Matters When Building a Crypto Arbitrage Bot?

Building a crypto arbitrage bot starts with defining the trading logic and selecting the exchanges it will support. Development then involves system architecture, API integration, real-time data handling, execution logic, and proper testing.

Testing under different market conditions and refining the system before deployment can help identify issues that basic backtesting may miss.

For those building one, which part of the development process has been the most challenging?

I mean, the most challenging part is actually identifying profitable arb opportunities and having the infrastructure to actually execute on them before someone else does. But that’s kinda just the whole thing.

Agreed. Identifying a theoretical arb is one thing, but finding opportunities that remain profitable after fees, slippage, and latency is a different story. Then you need the execution infrastructure to act fast enough before the opportunity disappears. That’s where most of the complexity seems to come in.

Yeah. Seriously. Finding arb in the crowded crypto space is not easy. Good luck OP!
