Some fans asked me what is the difference between 120 days and 200 days? Both can be applied, and the difference in parameters has little impact on long-term returns.

When using the moving average, please note:

1. Starting from the underlying logic, do not read the moving average parameters, and do not try to find the "magic moving average".

2. The moving average is a trend indicator, which is suitable for large time windows and can only be used as an embellishment for small time windows.

3. The moving average does not have a pressure or support function, it only reflects the trend direction.

The above, I hope it will be helpful to you.
