How to add code for custom indicator to have plots be selectable in strategy builder

[VinnyJalapeno]

I have created my own custom indicator with variables such as "Bandwidth." I want to be able to have these variables interactable within the strategy builder interface to make putting my strategy together easier. For example when in strategy builder, it would allow one of these plots to be selected as an input to be greater than the same plot 1 bar ago. My indicator displays perfectly and I am able to change inputs/int to a degree, but don't have that direct interaction in the strategy builder interface on being able to have a plot selected. I have tried direct coding the indicator.Bandwidth into strategy code but it does not recognize the plots.
How would I go about adding code into the line to make sure these are able to be interacted with?

Hello VinnyJalapeno,

I would suggest creating a new indicator using the new indicator wizard, that's just the new indicator option. In that wizard you can add plots, that will create public properties for the plots. By doing that all plots will be selectable in the builder.

[bltdavid]

Study the builtin indicators, something simple like @MACD.cs,
take a look at the properties region.

If you make some public properties in your indicator for the
Values array, (either by hand or following Jesse's suggestion)
then Strategy Builder will see those Series<double> properties
and then you can use them.
