You can use any EA (Expert Advisor) as long as we don't see multiple users executing the same trades/strategy. We limit one strategy per user, so if we see multiple users utilize the same EA, it may lead to the termination of your account. So even though the use of third-party EA is allowed, we recommend that each user use their own programmed EA. Be also aware of the server request limitation which is 2000 (modifications of TP/SL, orders modifications). The maximum position limit per day is 2000 as well.
E8 does not limit or restrict a user’s trading style or strategy so long as (1) the user is simulating trades legitimately, (2) the user’s trades conform to real market conditions, and (3) E8 could replicate these trades in its live capital accounts if it wanted to do so.
