Simply speaking of technical knowledge, the 5-minute cycle of 15 minutes and the 30-minute cycle of 15 minutes are the starting points. Generally, bulls or bears will enter the market at the 20 moving average, because it is easy to set a stop loss position when entering the market at this position. A five-minute cycle is the starting point. Look at 30 cycles. This is the general direction, and the relationship is mutually restrictive. Five minutes is just a small cycle, and 30 minutes is a big cycle. If you want to operate, you must consider it comprehensively. You can trust me privately if you have any questions.
