Yes, we allow our traders to utilize the martingale strategy.
You can use whatever strategy you want, just be aware of prohibited strategies such as:
Abuse of feed
Freezing, High frequency
straddling
You can read it in more detail in the terms & conditions.
We do not prohibit specific strategy types like martingale, and we allow traders to operate their edge as long as it can be executed under real market conditions.
Regarding EA usage, 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.
Also be aware of other limits, such as :
Open-order cap at time: 100 (active pendings + open positions)
Server requests per day: 2000 (order place/cancel/modify, TP/SL edits, etc.)
Max positions per day: 2000 (per account)
