What do you do to a trading strategy that already earns you a good percentage in profit. do you still try improving on it to ensure it does not fail? or do you let it be until it starts showing signs of failure?
It is a simple question but I think answers and opinions will be different considering that some traders may fear further tampering with the strategy, others will no want to wait until it fails, what is your style?
There's nothing wrong with improving, as long as you are profitable and you learn something new, so it's good.
But for me, improving it or mastering the strategy is already good, even a small percentage of profit, as long as it is consistent - it is already profit. As long as your capital is well protected - all good.
