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?
If it were you, what's would you do with a trading strategy that has earned you huge amounts of money? It is very simple, just keep updating the strategy has the market structure keeps changing.
I used to advise some people about trading and the importance of making sure that their trading tools are up to date so that it does keep lagging. Lagging strategy can be a disaster to us if we don't keep updating them. In a better way that would not bring loses to us just because we don't update the strategy often time.
