Anybody uses Trailing stop while scalping ES or MES? How do you decide on size for the Trailing stop?
Why/why not?

Hey stumbras,
The approach I use is to examine my setups and trades, historically, and see how much maximum adverse excursion (MAE) you incurred on entries. I record this data every day for every setup and can see on a rolling basis how much heat I took and how far the move went in my direct (MFE). This helps me set stops and targets.
