Creating 3 Moving Average Indicator

[kezyclaire]

Hi,

I am just getting started with NinjaScript and I was trying to plot 3 moving averages but it doesn't seem to work it right. It is only showing 1 moving average with the below code. Kindly help me identify what is wrong with my coding and is there something missing to associate the value of plots from the moving averages variables. Thanks.

Hello kezyclaire,

Thanks for your post.

Please see the attached example script demonstrating how to add three plots to a script using AddPlot() and how to assign values to those plots.

You could compare the attached example script to your script to see where differences might be.

See the help guide documentation below for more information about AddPlot() and assigning values to plots using the Values collections.

AddPlot: https://ninjatrader.com/support/help...t8/addplot.htm
Values: https://ninjatrader.com/support/help.../nt8/value.htm

Please let me know if I may assist further.
