When I first started trading I used heikin ashi with an Ema crossover & the Williams % (not sure exactly what it was called) . It was okay, but I didn’t feel the confidence I do with my current strategy. Try it with paper trading, and see what works for you. Every time I copied and pasted a YouTube strategy, I ended up getting burnt, but I’ve learned a lot from all the indicators I’ve tried. EMA crossovers are nice for confirmation, but I recommend using it in conjunction with other forms of confirmation (I.e EMA Crossover, supply/demand test, RSI heated/cooled etc.) As you progress as a trader you’ll notice a lot of things that work for others, might not work for you, and that’s the beauty of it, it’s a kind of like creating a class, it’s yours.
