Hey, good luck with the challenge. I’ve thought about doing this as well. I know as long as you have positive P/L and did not break any rules, your challenge will be extended so I guess don’t worry too much about time. I would start with trying out one of their 2 week demos and seeing if the strategies generated with MetaTrader-Demo data source is sufficient. They give you stats at the end of the demo so it’s a good way to see if your EAs break any rules and I believe you can keep requesting demo accounts so you can keep trying until you feel comfortable.
