How do you calculate/evaluate the probability of your trade?
Is there any actual systematic or defined structural method to do it?
You don't calculate probability of a trade. You calculate statistics on multiple trades within a system.
Look up "Van Tharp Expectancy".
You better calculate max loss of a trade then you already have 100% of the probability ,when it goes against you (which might just be all you ever need...)
What else do you want to calculate ?
Or better said what else can you calculate ?
To that level of certainty might it add..
