In the image, a scanner for MACD using both its values: MACD and signal line. Cells have multiple colors, the first part of the cell is green if the MACD is greater than 0 otherwise red, the second one is green if the signal line is greater than 0 otherwise red. See the cell for USDJPY H4 where the first part is red and the second one green, that means the MACD is lower than 0 and the signal line is greater than 0, all other cells have the same color. Have you seen how much information you can get from colors? Imagine how much time you would need to do this manually.
