printing indicator

[alibanez]

Hello. I'm making my first indicator an I have a problem. When I use a period distinct to 0 I cannot do that NT print the line. My code is:


protectedoverridevoid OnBarUpdate()
{

Print((Low[0]*(1-2*((((High[0]-Low[0])/((High[0]+Low[0])/2))*1000)*0.001))));
//Print((Low[1]*(1-2*((((High[1]-Low[1])/((High[1]+Low[1])/2))*1000)*0.001))));


LowerBand.Set(High[0]);
HigherBand.Set(Close[0]);
}

In this way it works, but if I quit the slass from
//Print((Low[1]*(1-2*((((High[1]-Low[1])/((High[1]+Low[1])/2))*1000)*0.001))));
then don't draw anything. Can You help me?. Thanks.

Hello albinez,

Most likely you are running into this issue here:
Make sure you have enough bars in the data series you are accessing

Add the following lines to you OnBarUpdate() method:
if (CurrentBar < 1) return;

You should be able to resolve for the snippet you posted.
