I read Firm's reply to one client who says he made 600k profit but it was denied by firm for payout, Reason : Martingale strategy.
I am new to your firm, not yet signed up. But want to sign up.
Your 50k account says, I can hold 8 minis or 80 micros at a time.

Will i be allowed dollar cost averaging ?

Will I be allowed to add trade mini / micro to add on to loosing position ?

I am writing this because, the rule for 50k account says i can hold 8 minis or 80 micros at a time.

Please clarify. Thanks
