Can u point me to code 2 show each bar with a higher high & higher low?

#property indicator_chart_window
#property  indicator_buffers 1
#property  indicator_color1  Gray
#property  indicator_width1  1

double ExtSignalBuffer[]; 

int init() {
   IndicatorDigits(Digits+1);
   SetIndexStyle(0,DRAW_ARROW);
   SetIndexBuffer(0,ExtSignalBuffer);
   SetIndexArrow(0,252); 
  return(0);
} 

int start() {
  int limit;
  int counted_bars=IndicatorCounted();
  if(counted_bars>0) counted_bars--;
  limit=Bars-counted_bars;
  
  for (int i = 0; i<limit; i++) {  
    ExtSignalBuffer[i] = EMPTY_VALUE;
    
    if (iHigh(Symbol(), Period(), i) > iHigh(Symbol(), Period(), i+1) &&
        iLow(Symbol(), Period(), i) > iLow(Symbol(), Period(), i+1)) {
      ExtSignalBuffer[i] = iLow(Symbol(), Period(), i) - 20*Point;
    }

  }
}
