What is the Buffer Index Numbers for Blue and Red bricks in this indicator?

[Alirzen]

Hi friends. I hope you are enjoying a good day. I found an indicator from the developer Kaleem Haider from this link (https://www.mql5.com/en/code/15563). I find it helpful to my strategy. When I want to make an EA based on my strategy and this indicator, for Buffer Index number I have a problem. It's basically "n" and not a number. Can anybody help me with the Buffer Index Numbers of Blue bricks and Red bricks of this indicator? I'll attach the indicator to this post.

Alirzen: t's basically "n" and not a number.

1. int OnInit(){
      int n=0;
      SetIndexBuffer(n,dSignalBuffer,INDICATOR_CALCULATIONS); n++;
   

   Of course it's a number. dSignalBuffer is zero the next is one, etc.

2.             dSignalBuffer[i]=OP_BUY;
   
               dSignalBuffer[i]=OP_SELL;
