The so-called time-sharing chart is actually the change of K-line charts in different periods. For example, 8 30-minute K-lines are one day, and the opening of 1 day is 4 hours = 8x30 minutes. Set the ma1 of the 30-minute K-line to 8, this moving average represents the daily line; ma2 is set to 8x5=40, this moving average is the weekly line.
