Hello,

Thank you for writing in.

When your indicator is looking at the Bar object, for instance CurrentBar, you have to make sure that you have enough bars to look at.

Many indicator have a parameter of Period meaning how many bars to calculate to plot. Let's take EMA and I set the period to 10, the indicator has to verify 10 bars before calculating.

For example:

if (CurrentBar <= 10)

return;
