Day trading depends on the variety. 15 minutes k line is not much. You can enter the market in 5 minutes, 15 minutes to take profit, and you must stop loss in 5 minutes. For example, for coke iron ore, 5 minutes is good enough for the profit of day trading. Back to the point, what you said is an introductory method. The entry method I am using now is to judge an effective top and bottom from the market that has come out by using wave theory and K-line shape of the top and bottom. When you find the right variety, then you can trade with the method of fixed entry. I take doing more as an example. My fixed entry mode is 20 and 60 moving averages and 2K, and I directly chase the 60 moving averages, all of which have fixed entry points. It is suggested that MA60 and BOLL20.20.2 can be configured in the main map of the disk, and the historical market can be judged by combining the top and bottom to see which bottom is more standard. The top and bottom figures are mostly five stars, crosses, W bottoms and Yang pregnant bottoms, and then the profit rate can be judged by wave theory. Look at the opening with BOLL, enter the market with 60 EMA and Brin middle rail, in strict accordance with 2K. Below I have pictures of three entry modes, which are easier to understand.
