Momentum Indicator with 2 Extra Parameters.

Similar to this post:

https://ninjatrader.com/support/forum/forum/ninjatrader-7/indicator-development-aa/19359-momentum-indicator-adding-lines

I want to add 2 lines to the momentum indicator. But I would like to be able to pass in the line values as parameters to the initialization of the momentum indicator.

For example, instead of the normal instantiation:

Momentum1 = Momentum(SMASlow, Period);

I would like to be able to instantiate like this:

GreenLine = 0.02;
RedLine = -0.02;
Momentum1 = Momentum(SMASlow, Period, GreenLine, RedLine);

The result would look the photo attached.

In this way I am able to change the position of the green and red lines when the indicator is instantiated instead of just having a hard coded red and green line that can't be changed.

Thank you for your help!

Hello vitalpilot,

Start by making a copy of the script.

To add a line (with a price marker) use AddLine().

To set the lines added with AddLine() set the Lines[index].Value.

To add a horizontal line (with no price marker) use Draw.HorizontalLine().

Thank you so much for your super fast reply. I appreciate the massive amount of contributions you have made over the years ChelseaB.

I discovered I had the original Momentum type set on the attribute declaration in my strategy definition, instead of my new type.

What I had:

private Momentum Momentum1;

Fixed:

private MomentumCustom Momentum1;

Thank you again.
