Do you satisfied with your current level of discipline.
Do you still have stupid trades because of discipline?
Shell I accept stupid trades in some why?

Umm I know several pros who made stupid trades. Some are some REAL BIG stupid trades. Pros certainly aren't perfect and I have yet to find one who ALWAYS executes according to their "proven system." They are skilled humans but because they are human they will sometimes fail and not follow their plan. All pro athletes screw up sometimes. Even the exchanges screw up...Stupid trades? Not for pro. Only newbies like it and keep repeating it emotionally.
Pros only execute trades according to their proven trading plans.
We live in an imperfect world with imperfect humans filled with uncertainties. It is life!
