What do the three lines of the time-sharing chart in futures represent respectively? I know the white one. What about the other two yellow lines? I was told that the yellow line above is the average line. Hello, landlord. The yellow line that works is the moving average, which represents the average price, that is, the settlement price after the close. The purpose of existence is to clearly see today's settlement price. The bottom yellow line is the position, and the bottom yellow-green line is the volume. Red stands for up and green stands for down.
