Why won't anything draw? Sometimes this indicator has crashed MT4
limit=Bars-counted_bars;
where is "Bars" declared and which value has it ? zero ?
as far as i can see, the script wouldnt even compile...
"Bars" is not a problem, but you need brackets around the for-loop block:
for(int i=0;i<limit;i++)
{ // open bracket here
PivotPoint[i] = (High[i+1]+Low[i+1]+Close[i+1])/3;
Resistance3[i] = PivotPoint[i]+PivotPoint[i]-Low[i+1]-Low[i+1]+High[i+1];
Resistance2[i] = PivotPoint[i]+High[i+1]-Low[i+1];
Resistance1[i] = PivotPoint[i]+PivotPoint[i]-Low[i+1];
Support1[i] = PivotPoint[i]+PivotPoint[i]-High[i+1];
Support2[i] = PivotPoint[i]-High[i+1]+Low[i+1];
Support3[i] = PivotPoint[i]+PivotPoint[i]-High[i+1]-High[i+1]+Low[i+1];
} // close bracket here
"Bars" is not a problem, but you need brackets around the for-loop block:
Actually, That needs to be changed so you don't reference the non-existent High[Bars]
limit=Bars -1 -counted_bars;
where is "Bars" declared and which value has it ? zero ?

I'm trying to plot pivot points, their resistances, and supports as graphs (similar to that of moving averages) for any period (based off a bar's predecessor), so I can find such for any bar, at any given time. Basically the purpose is to find what supports and resistances based off pivot points would have been in the past for any given bar. Below is my code; why won't it draw the lines? Sometimes when I choose it as an indicator, nothing happens and MT4 freezes. What is wrong with my code? Surely this isn't so complex MT4 can't handle it!
