Personal EAs are acceptable, however commercial EAs, those designed for passing challenges or involving copy trading are not permitted. We do allow expert advisors but they are only supported on Platform 4&5, and must not violate any of our prohibited practices.
EAs aren't supported by DX Match and cTrader. It's platform technology specific, not necessarily "not allowed." Please note: We do not allow HFT bots (usually, this is a form of latency arbitrage that is specifically prohibited in our T&Cs).
