Trade outcome A: I get my p&l target and subsequent higher exits
Trade outcome B: I get a pl tgt, then it fails and the back stops
Trade outcome C: No pl tgt, trade goes entirely against me ("normal loss")
Trade outcome D: outsized loss.
The problem with D trades is not only the outsized loss, but the way I am prone to tilt afterwards and have not just an outsized loss but a devastating losing streak. Let's be clear: I bring that on myself.
The prevention is the same as the cure TRADE SMALL SIZE.
