When i used to trade i only used bollinger bands and a few more indicators that can just help you to predict the price, but they are not exactly, it is just an estimator because there is no way to predict the price, you all know that the price is only determined by the reactions over other prices, so the price is pure fantasy, because it is created only by words and other kind of reacts over the government and a big list of other things. But yes, bollinger bands and a RSI are the most accurate indicators if you want to trade properly.
I often use BB, BBW to measure market breadth, RSI to determine trading, MACD to determine the trend of increase and decrease, and also EMA to identify long-term trends. I find these indicators quite effective. How often do you mix?
