Indicator plotting only 0 for positive/negative values

[EC_Chris]

Hello,

I have a volume-based indicator I have created. The plot is not overlay, and plots in the subplot.

Everything is working for the plot and the indicator. The issue I am running into is the indicator is set up to calculate both negative and positive values, and it seems because of this, the indicator is only plotting 0.

When I force the indicator to not plot negative, the indicator works. But when I allow both negative and positive values to calculate, again, the indicator only plots 0.

Does NinjaScript automatically force a 0 for some instances (say volume based indicators) where it won't plot negative values?

Is there a way to allow negative values to plot in this circumstance?

Thanks

Hello EC_Chris,

Thanks for your inquiry.

NinjaTrader 8 will plot a 0 for invalid data points when NinjaTrader 7 would use the value from input series. This could be for example, when an indicator's OnBarUpdate() method is called and a plot's value is not set for that bar iteration.

You should still be able to plot negative values for your indicator. You may see that the setting an indicator plot to a positive or a negative does work.

Values[0][0] = (CurrentBar % 2 == 0) ? 10 : -10;

I may suggest to make sure that the indicator is in fact setting a plot value for that bar iteration. I've also included a link for IsValidDataPoint() that will tell you when an indicator plot is a valid data point before referencing that value.

I'm happy to be of further assistance.
