I don't use price action. There are many other trading techniques that do not involve trading without indicators
Experimenting with different indicators is the key. When we practise several indicators, we come to know what will work for us and what won’t. Combining indicators is a good practice. But that should be done when we know the indicators in detail and how to use them. Combining too many indicators at once becomes a mess.
I use only those indicators that are relevant to my trading. At the beginning of my trading journey, I decided to use seven indicators, and the strategy became horrible. I now use only three because I don't want to ruin my trading because of "stuffing" the indicators.
