Many brothers don't need to understand why simpler systems have more advantages? Because of strong execution ability. Execution is a millennium old challenge for traders. A friend often sends me a picture, should I enter this position? At first glance at the various trend lines, pressure support, moving averages, and MACD on the chart, which are multi cycle, I also felt dizzy. We can think of it this way: when you are preparing to attack on the battlefield, everyone around you gives you different opinions. The trend line says wait a little longer, the moving average says it's in place, the pressure says fast forward and even breaks the level, and MACD says I don't have a golden cross yet. With all this chatter, you will become irritable and confused. What if it's a simple trading system? Unified standards, no ambiguous areas in operation, the moving average has already been broken, and we can wait for the trend line to break before entering, which is clear and concise. At this point, your execution ability will greatly improve because there is no need to think and ponder extensively anymore. As long as you execute, it will be easier to make such decisions. A simple trading system is also easy to review and optimize. We need to consider that a trading system contains many variables, including several indicators, entry conditions, stop loss and take profit settings, as well as fund management. There are many details that need to be reviewed and tested one by one to see the overall effect. If your trading system is very complex, it can be a nightmare to review, and it may take a long time and a lot of patience for you to persevere. The scariest thing is that after reviewing, suddenly there is something wrong with a parameter, and you have to start over again, which is no different from the collapse of the sky. At this point, a simple trading system demonstrates its advantages. The review process is simple, and there are fewer options that need to be modified. We can conduct backtesting at a faster speed, and the progress of entering the actual trading will also be faster, without testing patience as much. So the trading system is a pile of details, and we shouldn't set too many obstacles for ourselves in the early stages. To get back to the point, continue to blindly buy 10 SOLs
