from my experience, trading indicator doesnt work well in crypto. i test many time and often fail with those indicator
i believe in price action which can work better than indicator. furthermore, price action is simpler than indicator
Indicators are calculated based on the past history of price thus they lag behind the price in some cases when an indicator signals buy or sell the price goes the other way due to lagging of the indicator, as you said Price Action rules in trading this is based on how the price behaves and how it is formed would determine buying and selling position or zones of the market.
