....
protected override void OnBarUpdate()
{
  double v1 = Indic_2(0.5, Order, Period).MyLine[0];  // <----------- How to convert this line to NT8 ???
  double v2 = Indic_2(0.2, Order, Period).MyLine[1];  // <----------- ... and this one?
}
[Description("")]
[GridCategory("Parameters")]
public int Period
{
  get { return period; }
  set { period = Math.Max(1, value); }
}

[Description("")]
[GridCategory("Parameters")]
public int Order

Hello vindiou,
Thanks for your post.

There is not anything specifically wrong with the lines with arrows. You will need to convert all of the DataSeries class items to be Series<double> instead.

Thanks, yes there is, if I try to compile this line in NT8, I get: "No overload for method 'Indic_2' takes 3 arguments" CS1501

Probably because you are calling MyLine which is a DataSeries class item. Convert that to a Series<double>.

Hello,

I am not sure if I posting this request in the correct location, if not i'm sorry. I am finally moving completely over to NT8, but there 1 indicator that I have been using in NT7 that of course no longer works, is there anyone who would be willing to convert this indicator to the NT8 format, it would be greatly appreciated.

Thank You,
Dorian

If this was obtained from a vendor or community member, my advice would be to contact the vendor or original author to request the NinjaTrader 8 version.
