I think this is a common case. I have a strategy. I am calculating a series of values used in the strategy. I want to display this series on the PricePane. As an example, let us assume that my series is SMA with period=N. As you know, SMA values are not available for the first N-1 bars. So, instead of diplaying some preset values like Close-Close=0, I would like the chart to display no SMA values for the first N-1 bars. How shall I do it?
Here is the code:
