Ehlers super smoothing filter

[Graci117]

I am looking for Ehler's Super smoothing filter. I found the old code from 2008 and want to convert this to NT8 and have attached it here. Any help will be so much appreciated.

I converted the following code from the EhlersSuperSmoothingFilter to C#. However, I am not sure how to convert this code to a NT indicator -

var a1 = Math.Exp(-Math.Pi * Math.Sqrt(2) / Period);
var coeff2 = 2 * a1 * Math.Cos(Sqrt(2) * Math.Pi / Period);
var coeff3 = - Sqr(a1);
var coeff1 = 1 - coeff2 - coeff3;
var filt = if Double.IsNaN(price + price[1]) then filt[1] else coeff1 * (price + price[1]) / 2 + coeff2 * filt[1] + coeff3 * filt[2];

The filt line (last line) might not be accurate as I had no idea how to test. I want to plot the filt line.

Hello Graci117,

Thanks for your post.

Unfortunately, due to the code-breaking changes to the structure of NinjaScripts as well as changes to the NinjaScript properties and methods, no scripts created for NinjaTrader 7 will import into NinjaTrader 8.

My advice is to start by creating as much of the script as possible in NinjaTrader 8 using the Strategy Builder (or Strategy Wizard). This will create the framework of the indicator or strategy which has large changes from NinjaTrader 7 to NinjaTrader 8.

Then copy all code from the NinjaTrader 7 scripts OnBarUpdate to the OnBarUpdate of the NinjaTrader 8 script. This will introduce errors that will need to be resolved.

Below I am including a link to a list of the code-breaking changes from NinjaTrader 7 to NinjaTrader 8. This help guide will be the best way to see how things have changed from NinjaTrader 7 to NinjaTrader 8.

When first starting to convert scripts, I myself would open the NinjaTrader 7 help guide and the NinjaTrader 8 help guide to the same sections so that I could compare. The majority of code supported by NinjaTrader is included in the help guides.

Below is a link to a forum post with helpful information about getting started with NinjaScript.
