What key factors do you consider when designing or choosing an EA for Forex trading, and how do you ensure it aligns with your trading goals and risk tolerance? Does your broker allows all types of EAs?
No EAs at all. Have not seen any good one in all the years. If you look on the mql5 market which has all kind of EA stuff you can imagine of, you will get very disappointed in the end when realtime tracking those.
cause it's a crap platform like most of them. they display best results in testing and totally different results in real time trading. zillions have been loss in the ea scam, but people wanna believe and so let nature do it's thing.
Stay away from the "EA" ecosystem, it's mainly (or actually, exclusively) a bunch of random walk crap and martingale scams. Feel free to confirm that by yourself but every hour spent there could be spent on something better.
