I do love martingales. They can and do blow accounts, demo and real. I have built serveral EAs using a form of martingale. Let me know if you want a copy. Min e have lots of bells and whisles built in and Im still not using it on a real account. Some times I can have month triple and then blow the account twice in one week even with MM and safety built into the EA. Its risk and fun....BUT dangerous yes.
