DIF is the express line.

Later, with the widespread use of MACD, columnar lines (BAR) were introduced, commonly known as "red and green columns". The red and green columns represent the distance between the fast line and the slow line, which has no actual impact on the indicator. It is just to make it easier to observe and use the indicator.
