Each technical index can exist for a long time because it has its reference significance in a certain range. How to use the index mainly depends on personal logical thinking and experience accumulation. Some futures experts can do things that everyone can't catch up with without looking at any indicators, which is the best example. I recommend reading the most classic john murphy's Analysis of Futures Technology, which is the most comprehensive introduction to all technologies. You can refer to MACD and EMA systems. There are no absolutely reliable indicators. Otherwise, everyone can become a billionaire through the futures market. To be a leader, you also need to hone your skills and master them. I hope my answer can help you. If you want to know more about futures, you can trust me privately.
