Indicator Not Plotting when changing instrument

[BuhoTrader1]

Hi,

I have created a simple indicator that it is plotting correctly when I choose certain forex pairs, but when I chance the instrument from EURJPY to GBPAUD per say, it doesn't plot anymore. Also it seems to only work with time frames smaller than 10 min, so when the 15 min or 30 chart are selected the indicator doesn't work anymore. The estrange thing also is that with GBPUSD pair the indicator does work when time frames greater than 10 are selected, but will not work with a 17 min chart or greater. Very, very weird. If any body can help me with this I would greatly appreciated.

I have attached the indicator in case you guys want to test it on your side.

Thanks for all the help provided

Hello BuhoTrader1,
Please make sure you have enough bars before accessing historical values. Please refer to this post which further describes the scenario.

if (CurrentBar > cantidad && cantidad >= 3)
{
  //do something
}

thanks for the info, I looked at the other post and adding the line
if (CurrentBar < 1)
return;

provided in the post made it work for the other forex pairs that were not working. The problem of only being able to plot this indicator in charts smaller than 10 persists tough. and I have plenty of bars to test the indicator on.Llike I described in the first post, I may have the GBPUSD with a time frame of 15 min, and the indicator would plot fine, but if I change it to EURJPY, the same chart, same amount of bars, it wouldn't plot. I tried the code line you provided and it didnt seem to fix the issue. ANy other ideas?
Thanks,

Hello BuhoTrader1,
You have to make sure you have checked for the bars at the appropriate place.

protected override void OnBarUpdate()
{ 
	int cantidad = 0;
	

				
	if( Close[0] < Open[0] ) //Si es barra roja
	{
		do
		{
			cantidad = cantidad + 1;
			[B]if (CurrentBar < cantidad) return;[/B]
			
		}while(Close[cantidad] < Open[cantidad]);
		
		if (cantidad >= 3)
			Bearac.Set((Open[cantidad] + Close[0] )/2);
	}
	else if( Close[0] > Open[0] ) //Si es barra verde
	{
		do
		{
			cantidad = cantidad + 1;
			[B]if (CurrentBar < cantidad) return;[/B]
			
		}while(Close[cantidad] > Open[cantidad]);
//				
		//Bullac.Set(cantidad);
		if (cantidad >= 3)
			Bullac.Set((Open[cantidad - 1] + Close[0] )/2);
	}
}

Now the indicator dont throws any errors.
