I do use macd divergence but not for day trading, way too slow, and if you a beginner, trend is your friend. For me it took a real good five years to study charting reversals, and yes there are nuances in this price action, but way too many and most would not understand, trading is like levels of knowledge, more you learn, what you didn't see last year, NOW you understand today and again next year what you thought you understood becomes clearly then. Much better for younger traders to trade in direction of trend, we all want to buy low and sell high and diverences entice us to find bottoms and tops, but not practical till you know how to break down swings, waves within a swing, number of bars within a wave, ranges of individual bars, what is normal bar range of a wave and which waves are trend waves and which are ending waves, much much study so to better understand reversal patterns, with as you see slope of a trend happens after a "thrust" bar. Thrust bar is like a bar that occurs completely above like 20 sma, no part of bar is touching the 20sma, so now we look for pullback, and that can even be as simple as the 20sma itself. Study what happens if you enter on the 20sma, develop protective stops, targets, and snowballing into possible system.
It is best to study price at first, like 3-4 years if you aiming to make this a career, then you can add like RSI, but I use indicators as faster approach that staring at bars, I already know what the indicator will be doing most of the time, but it is just a down and dirty fast approach.
Good luck
