Either you keep it that way or try to improve and upgrade it, that’s already up to you. The important thing is, you are still benefiting from your strategy, and as long as it’s doing a great job, you will still be in consistent profits. However, you can always try to create a new one and develop it that will suit to your trading style. Having a single strategy that consistently works for you is good, but we can’t also deny the fact that having another potential strategy that will serve as a back up will help you avoid future mistakes and losses.
