Transferring Old Custom Indicators From NinjaTrader 7 To NinjaTrader 8

[vern13]

I have a group of indicators I wrote in Ninjascript for NinjaTrader 7. Is it possible to transfer them to 8? For reference, a portion of the original script looks like this:

if(CurrentBar<2)return;if((High[0]<=High[2])&&(Open[0]<Close[2])) DrawDiamond("tag1" + CurrentBar.ToString(),true,0,High[0]+(TickSize*50),Color.Red); else RemoveDrawObject("tag1"+CurrentBar.ToString());
}

Any help is much appreciated. Thank you in advance

Hello vern13,

Thank you 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.

Below is a link to the migration guide which lists what can migrate from NinjaTrader 7 to NinjaTrader 8.

If this is a script you have created that you would like to port to 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.

The help guide will be the best way to see how things have changed from NinjaTrader 7 to NinjaTrader 8.

When first starting to port 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.
