Thats where the mm system comes into play as the TP is based on how accurate the system becomes ie the more accurate the more the profit it takes and vice versa. but the risk is alway the same as you have a max DD that your comfortable with because you set it to what you want.

This is all theory apart from the mm system I know that works but the hard part is getting the probability part correct. ie what are the chances of the TP being hit if a open either a buy or a sell based on history.

The higher the prob will determine the trade direction, it sounds logical to me.
