Hello jay1987,

Thanks for your post.

The Plot.Set() method is only available to use in NinjaTrader 7. This will lead to compile errors in NinjaTrader 8.

To assign a value to a plot in NinjaTrader 8 you could do something like Plot0[0] = X; where X is the value are you assigning to the plot.

See this help guide page for more information about the AddPlot() method and assigning value to plots: https://ninjatrader.com/support/help...t8/addplot.htm

Below I am including a link to a list of the code-breaking changes from NinjaTrader 7 to NinjaTrader 8 for you to review.

Hello jay1987,

Thanks for your notes.

You are not using the correct syntax for GetCurrentAskVolume() and GetCurrentBidVolume() in your script.

Parentheses need to be added at the end of GetCurrentAskVolume() and GetCurrentBidVolume() since they are methods.

GetCurrentAskVolume()
GetCurrentBidVolume()

See the syntax for these methods in the help guide documentation linked below.

GetCurrentAskVolume(): https://ninjatrader.com/support/help...taskvolume.htm
GetCurrentBidVolume(): https://ninjatrader.com/support/help...tbidvolume.htm
