Adding plots and output to existing indicators that are display only

[chinaexpert1a]

Hi,

I'm new to Ninjatrader and coding in general, but it seems there is a common problem of using shared indicators in Strategies for trading in Ninja. I have downloaded a bunch, some users have great work, and so I have some I'd like to use in a backtest, and a strategy, but they don't compile or aren't providing data to Strategy Builder. For instance, the wiseman fractals, key reversals and others do display on a chart, so they work for manual traders but not algo builders. My question is, how to add a reference in the ninjascript that lets me work with such an indicator that is display only? Do I use AddPlot()?? or something else? and where?

A relevant snippet, and instruction on where and how to place it in the code, would be greatly appreciated.

Thanks all so much!

Hi chinaexpert1a, thanks for your question.

The indicator must expose either a plot via the AddPlot method or a public Series<T> object. We have an example of the ladder here:

It looks like the wiseman fractal indicator has two plots which should be available in the builder but the other signals would need to be exposed as a public series.

Please let me know if I can assist any further.
