Traders who use indicators say they provide accurate entry and exit signals but may sometimes lag. Price action traders argue that indicators rely on price data and thus are unnecessary.
Actually I don't see much of a difference here. Price action people still need to say an entry and exit, and guess what, they're going to be doing some kind of TA anyway to determine what that is at least in a small part.
You know what a 'pure' price action trader is? Normies who FOMO (buy when price is bullish) and who panic sell (sell when market crashing). I thought I was smart in 2017 and 2018 buying 50% dips, buying even more at 80% dips, 90% dips. Lol at myself.
