if you have large capital in your account, it's safe to use ea but if you don't have large capital in your account then using ea can be risky for you, so I have to say that only use it when you have large amounts in your account. and Forex has become a high-risk business, so why do we have to take other risks using certain EAs?
it doesn't matter if we risk small funds to get big profits. But, why do we have to place large funds / capital if we still have to face multiple risks? I think, if you are really interested in using EA, you must choose EA that can turn small funds into big profits in a short time.
