How to make banded color background BUY SELL GREEN RED

[Semnomic]

Hi i have seen custom indicators where the BG changes to RED/Green depending on when the EA is in buy sell mode. (the whole screen changes color)

I have a custom indicator (icustom) linked to EA, my EA sets itself to BUY or SELL mode, How can i paint the area behind buy/sell as it paints  light red and green to match the MODE at the time ?

So the screen will be banded RED/GREEN Stripes of various thicknesses.

Hope that makes sense, I was trying to do it with lines/buffers but got nowhere :(

Im OK with most code so just a tip will do.

In MetaTrader 5 you could paint areas with buffer plots, like in the following example: https://www.mql5.com/en/code/18900

In MetaTrader 4, however you cannot do that, so the easiest way a full rectangular background area can be achieve, is by placing OBJ_RECTANGLE_LABEL on the chart which is not fixed to any anchor points, but to the screen coordinates. Alternatively a OBJ_RECTANGLE can be used if you wanted it anchored to a particular time range.
