I appreciate the response Kalmar. I'd like fHighCurrent and fLowCurrent to be a series.

Code below, but Zorro crashes. Have I missed something ?

Code

function run()
{
set(PLOTNOW, TICKS);
PlotScale = 8;

StartDate = 20160101;
EndDate = 20160331;
BarPeriod = 60;
LookBack = 3;

vars Price = series(price());
vars Highs = series(priceHigh());
vars Lows = series(priceLow());

var fHigh = FractalHigh(Highs, 3);	// short term highs and lows
var fLow = FractalLow(Lows, 3);
static vars fLowCurrent = series(), fHighCurrent = series();	// fractal values are retained between runs ...


if(fHigh != 0){
  fHighCurrent[0] = fHigh;
  plot("Recent High", fHighCurrent[0], MAIN|DOT, BLUE);
  printf(" fHighCurrent[0] = %.5f, fHighCurrent[1] = %.5f \n ", fHighCurrent[0], fHighCurrent[1]);
}

if(fLow !=0){
  fLowCurrent[0] = fLow;
  plot("Recent Low", fLowCurrent[0], MAIN|DOT, RED);
  printf(" fLowCurrent[0] = %.5f, fLowCurrent[1] = %.5f \n ", fLowCurrent[0], fLowCurrent[1]);
  
}

}
