How do I change the upper and lower plot of WilliamsR indicator programmatically ?

[elirion]

Dear Experts,

I am trying to use the WilliamsR indicator as part of my strategy.

I created the indicator this way and have it displayed on my chart.

private WilliamsR myWilliamsR;
myWilliamsR = WilliamsR(21);
AddChartIndicator(myWilliamsR);​

How am I able to manipulate this part found within the indicator codes

AddLine(Brushes.DarkGray, -25, NinjaTrader.Custom.Resource.NinjaScriptIndicatorUpper);
AddLine(Brushes.DarkGray, -75, NinjaTrader.Custom.Resource.NinjaScriptIndicatorLower);
AddPlot(Brushes.Goldenrod, NinjaTrader.Custom.Resource.WilliamsPercentR);​

Essentially I am trying to set the upper line to be -15 and lower line to be -85. Thank you.
