i am not fond of using trading indicators, as during the whole trading path i understood that they are less effective than just ordinary trend lines and support & resistance zones. these days i tryna build up my strategy based on the volumes and sometimes i can include bollinger bands. i used rsi, ema, sma, ma and all of them seems to me weird and uneffective at all.
idk, how traders still use indicators, but of course, if your strategy is based on particular indicators you have a full right to use them, nobody restricts you in this right besides your broker. i realise that indicators create more difficulties such as divergences and convergences.
