Trailing Step is the minimum step at which SL is moving. What do you want to move if you don't have SL? Pending orders?
This hedge again... I think this is loss of time 🙂 I wrote this 100 times here and there, but I still believe that hedging (in the same symbol) is only the worse way to do martingale. And it's so hard to build, that I also have problems to tell the people how to make it right.
