The 5-day moving average is to add up the points of 5 days and divide them by 5, which is the point of the 5-day moving average.

Say why you can find out the location of next Monday or the next trading day.

Just add today's closing point to the known closing point four days ago and divide by 5, because the opening point of the next trading day is not much different from the closing point of the previous trading day, so even if it is a few points away, dividing by 5 will not be a few.

The longer the moving average, the closer it is.
