Indicator meaning

[Trader1529]

Good morning everyone,

can someone help me to understand the meaning of this part of the code of my indicator? What does it do?

       if(val1 > 0)
       { 
           v1[i] = High[i];
           counter1 = 1;          
       }
       else
       {
           v1[i] = v1[i+1];
           counter1++;           
       }

It propagates the previous value ,unless ,a new value comes in from val1 

it also keeps a counter which is intended to be bars since last change ,but if the system is not gated by new bar detection there will be issues with the counters usability
