In 2019-2020 I used a lot filbfilb's predator indicator and it was performing quite well at the time.
If you have an indicator that is performing well so what is the point of leaving it? Always follow what is working for you in trade and not to be confused by others because if you allow them get you deceived you can keep going round in circle and wasting your time. I like sticking with what works.
+1, if you don't find your indicator is not performing well for sure you are overthinking trying other indicators.
For me, sticking to and mastering a technique or indicators or how you do trades will help you to become a good trader. Having consistency is the key especially in trading because not all of the trades are winning.
