AddDataSeries destroys the chart

[Sweet&Sour]

Hi all,

I have an issue adding an additional DataSeries. This fully destroys the chart. Have a look at the attached image. Above is ok, below is the destroyed chart.

Thanks for your help...

Hello Sweet&Sour,

Thanks for your post.

The chart is not destroyed as it is still there. What has happened is that it appears the indicator is now being calculated using ^SP500 instead of AAPL. The ^SP500 is around 2900 which is what your indicator is plotting at. Because the indicator has its autoscale set to true, the chart adjusts to show the indicator plots as well as the AAPL dataseries which in this case appears quite small as its typical value is only 185 whilst ^SP500 is at 2900.

If you want your indicator to only calculate based on the chart bars (AAPL) then in your code you would need to add a line in the OnBarUpdate() such as: if (BarsInProgress !=0) return; however this may not be a satisfactory solution depending on what you want to do by adding the ^SP500 data to your indicator.

We highly recommend reviewing the helpguide section on multi time frame/multi instrument scripts as there are many considerations when doing so: https://ninjatrader.com/support/help...nstruments.htm

Hi Paul,

BarsInProgress != 0 solved my issue.
I'm just checking afterwards whether or not, the SPX closes for at least 3 bars above the sma50.

Thanks...
