EMA() does not take two double parameters. It takes a DataSeries and a double for the period.

You cannot do EMA(VAR1, 13). Also, when trying to access the EMA values you need to call the value itself, not the EMA DataSeries.

Needs to be EMA(Close, 13)[0] for instance. Where Close is not a double, but the DataSeries corresponding to the closing prices.

To make your own DataSeries see this article: http://www.ninjatrader-support.com/H...taSeriesObject

You do not use an = for .Set.

Please use:
Value.Set(someValue);

Because you are setting it to the exact same plot and overwriting it. If you want two lines you need to use it on two plots.

Plot0.Set()
Plot1.Set()
