I was not born with your trading gift. One day, through hard work, and perseverance, I will perhaps get there...
With no intent of playing guru, I offer you this advise...
Discipline is the number #1 characteristic needed.
Within that are line items...
The #1 line item is do not 2nd guess your (proven) systems/methods, which includes adhering to the associated risk management.
Over time, you will discover "inefficiencies". Those inefficiencies will be data based or personality based.
Have the discipline to learn the difference, and understand inefficiencies are not necessary. Losing is NOT inefficient, and for better or worse, losing IS necessary.
Good trading to you!
