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 I'm trading and I have a good strategy like you said that has been helping me to gain profit what I will do is to improve on it to make it look more better so I won't have any problem of failure in the future.
How will you have a strategy that is giving you money, making you gain profit in your trading and you will just wait till it starts failing because you believe all strategy will fail one day, if you have a mindset like this then you will never succeed as a trader, you will always have issues with that kind of mindset.
In life you don't have to wait till something fails, not only in trading but in other business you do try to always expand and improve yourself, the reason why some people are poor today is because they where just comfortable in a particular strategy and refused to improve there knowledge about that strategy they are using, when you fail to improve you will decrease and when you do you are in problem because you will start losing value and money at the same time.
