for me I prefer to use EMA and Fibonacci, ema really helps my trading activities, although sometimes the signals given are not always correct, and I think all indicators are like that too. but it is this approach that we must use to trade, and of course we must know how to read the ema where if it breaks, of course, it must immediately cut loss
EMA and Fibonacci can help you to determine the right time to buy or sell and I think that is enough to use that indicator in trading. If you can master the lessons about those indicators, I am sure you do not need the other indicators, but learning the other indicator will improve our skills. The more indicators that we can learn, the more chances to know when to enter and leave the market and take profit. And with some practice in real trading, that can really improve our skills to better.
