Do I have to remember certain rules or be really good at technical analysis to make accurate predictions? What tools or methods do you use to predict prices?
You don't have to remember that but evaluate, those indicators only contribute a few percent of accuracy, nor will they guarantee you trading success. So there is no method that we can suggest to you, using the same method does not always give the same outcome for every trader.
You have to combine several trading guides besides mastering some technical analysis, it can be like risk management and emotions.
