I need a very experienced coder

Modify the flag to improve the input logic. This indicator reads the buffers of up to three other indicators and provides buy and sell signals.

The main indicator is reading the buffers of two indicators, 1 is a semaphore indicator and 2 is a bollinguer bands indicator. My strategy is based on the fact that after the traffic light shows a red dot I wait for the price to break the band below BB and then I enter the market. In the two images I uploaded you can see one in which the background has changed to red when the traffic light indicator has shown a red dot. The indicator is reading the buffers of the two indicators I used and should have changed color when, after indicator 1 gives a signal, wait for indicator 2 to give a signal in the same direction. In the second image you can see how the color change of the background of the graph should be.
