This thread starts with a question, and hopefully will end with an answer. Given a $100 account and .1 lot sizes, how would you handle a system that indicates it may, at some unknown time, drop as much as $200 or more before picking back up? The obvious answer seems to be to wait for a typical draw-down of $150+ (in a parallel demo account) and then if you thought you could count on your data telling you that $200 is probably your max draw-down, then you should be good to go (live). Another variation could be to wait for a $100 draw-down (before going live), and then to take the next trade after a loss. If you take a loss on this one, wait for another (demo) loss in addition to the one you just took live. This is in the interest of finding out just how small an account could initially survive the perils of getting off the ground where the granularity (.1 lots) would seem still too risky for it to work. I am interested in starting with $100 and repeatedly bringing the account up to $300 (+200%) about twelve times in a row, just to prove a point. Of course, i'd like to do this in as short a time as possible, without a lot of waiting around for a significant draw-down in my proposed system. One way to shorten the waiting time would be to have several systems where the max draw-down data seems trustworthy enough. That way, it should not be long to get on board (live) with one of the systems.
