Ninja 7 upgrade to 8

[spotfx]

Hello, does the upgrade from 7 to 8 impact your strategy? I've been using ninja for a few years, if I upgrade to 8, will it impact my existing strategy? Thank you

Hello spotfx,

Unfortunately, due 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 NT8, my advice is to start by creating as much of the script as possible in NinjaTrader 8 using the Strategy Builder (or Strategy Wizard).
Create any variables, Inputs, and add any data series that are needed using the Strategy Builder. If you are creating an indicator, use the Indicator wizard to add a plot. This will create the outer framework of the indicator or strategy which has large changes from NT7 to NT8.
Next, copy all code from the NT7 scripts OnBarUpdate to the OnBarUpdate of the NT8 script. This will introduce errors that will need to be resolved. Typically these are minor changes to method and property names.

Below I am including a link to a list of the code breaking changes from NT7 to NT8.

The help guide will be the best way to see how things have changed from nt7 to nt8.
When first starting to port scripts, I myself would open the NT7 help guide and the NT8 help guide to the same sections so that I could compare.
The majority of code supported by NinjaTrader is included in the help guides.

I'm also including a link to a forum post with helpful information about getting started with NinjaScript.

If you get stuck at anytime looking for equivalent code for NT8, please send an email our way or create a post on our forums and we will be happy to assist.

If this is not a script that you have written, I would recommend you contact the vendor that creates the NT7 version and inquire if there is a new version available for NT8.
