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?
If you are having a strategy that’s really working for you, you don’t have to be relaxed, you should always look for a way to improve it, you don’t have to start waiting for sign of failure before you will improve your strategy, if the strategy which you are using fails before you start looking for a new strategy, or before you improve your strategy, then you won’t really be making money in the process of trying to look for a new strategy, or when improving your strategy.
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?
If you are having a strategy, you should know that the strategy won’t last forever, so I don’t think their is anything you are even suppose to be scared of. If you are scared that you don’t want to tamper with strategy which you are using, when you stop making money from it, then you won’t have choice than to tamper with it.
