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?
All trading strategies have failed times when market beat trading strategies so traders must have proper risk and trading capital management. They must avoid to strongly believe in any trading strategy and feel like it is unnecessary to use some weapons in trading like stop loss order or stop limit order. Such orders are helpful to defend their initial trading capital which can maintain capital of traders in long term.
It is very important to have prevention and risk management when you already know that there is no perfect trading strategy that can works well forever.
