Hi,

I don't think your system sounds very very good at all. It may be, but I think that there's a reasonable chance that you've just been very very lucky. You didn't give enough info tho so it might be OK.

There's no such thing in this game as a lock system, and even if there was I don't think people would give them out. Go to elitetrader.com and search for posts by acrary, that will give you some ideas maybe but more importantly it will give you a good base on understanding system design.
