If the indicator isn't showing an arrow, then the value read is typically EMPTY_VALUE (sometimes indicators use zero.) If it isn't, then you have the bar you want - stop looping.

You already said that. Saying it again changes nothing.

What part of "then you have the bar you want - stop looping" was unclear?

for(int I = 0; I < ???; I++)

i cant identify the body of loop

Why can't you? What part of "then you have the bar you want - stop looping" was unclear?

double arrows[];
int  Bars = CopyBuffer(
   indicator_handle,       // indicator handle
   buffer_num,             // indicator buffer number
   0,                      // start position
   Bars(_Symbol,_Period),  // amount to copy
   arrows                  // target array to copy
   );
for(int iBar = 0; iBar < Bars; ++iBar){
   if( arrows[iBar] != EMPTY_VALUE ) break;
}
Print("Found arrow at "+i);

You didn't state that previously and I know this thread wasn't in MT4 forum when I posted.

int iBar = 0;
for(; iBar < Bars; ++iBar){
   double arrow = iCustom( ... iBar);
   if( arrow != EMPTY_VALUE ) break;
}
Print("Found arrow at "+iBar);
