Hi guys,

whythe range bar is not costant?

Here I show you the difference between High and Low. Why is not costant? The code used below
Code:
var BarRange = 0.005;
//Range Bar
int bar(vars Open,vars High,vars Low,vars Close)
{
  if(Open[0] != Close[1]) {
    High[0] = max(Open[0],Close[1]);
    Low[0] = min(Open[0],Close[1]);
    Open[0] = Close[1];
  }
  if(High[0]-Low[0] >= BarRange)
    return 1;
  return 4;
}
function run()
{	
	set(PLOTNOW);
	StartDate = 20180601;
	EndDate = 2019;
	BarPeriod = 1;	
	asset("EUR/USD");

	plot("Range",priceHigh()-priceLow() ,NEW,RED);
	
}


thanks
