New Computer

[Marklhc1988]

Hi,
I am a lifetime subscriber to NT. I am contemplating getting a new computer. A couple of questions:

1) What is the easiest way for me to get my indicators and strategies over to my new computer?

2) I am currently running NT7. If I moved to NT8 will all my old indicators work?

Thanks, Mark Lewis

Marklhc1988, thank you for posting!

I would say the easiest way would be installing NinjaTrader on a second computer and restoring from a NinjaTrader backup created from the first PC on the second PC.

You may do this by navigating to the NinjaTrader Control Center on the first PC -> File -> Utilities -> Backup, and ensuring that you're checking the option to include the items you would like to restore (NinjaScript files).

Once you've ran a backup, move the file to the other PC by either emailing it to yourself or moving the file via flash drive. The location of the backup will be in the Documents -> NinjaTrader Backup folder.

Once moved to the other PC, you will have to download and install NinjaTrader (from here by entering your email) and then you can run a restore by going to the Control Center -> File -> Utilities -> Restore.

Also, please see the educational YouTube video below which also covers this:

Unfortunately, NinjaTrader 7's custom add-ons will not convert over by default to NinjaTrader 8. If you created the add-ons yourself, you'll have to convert them, or if you received the add-ons from a vendor, then you'll have to reach out to see if they have conversions.

There are a few key items to look for when converting your scripts from NinjaTrader 7 format to NinjaTrader 8, and we keep a Code Breaking Changes table updated in the NinjaTrader 8 Help Guide to assist in identifying changes or new implementations of familiar methods and properties from NinjaTrader 7: http://ninjatrader.com/support/helpG...ng_changes.htm

The biggest things that you will run into when converting will be:

Initialization has changed significantly. Initialize() has been replaced with OnStateChange(), which can be used to filter out different stages of the entire life cycle of a script (SetDefaults, Configure, Historical, Realtime, Terminated, etc.) OnStateChange() is fully covered in the Help Guide.

The names of many methods and properties have changed slightly, so you will need to refactor these in your code. The Code Breaking Changes table can make this task much easier, and there is also an alphabetical reference in the Help Guide that can help to find new method/property names: http://ninjatrader.com/support/helpG..._reference.htm

In numerous instances, you now have direct access to objects, where in NinjaTrader 7 you had to work with interfaces. For example, rather than the IOrder interface, you now have direct access to an Order object and its related fields. This will require a change in the way items like this are handled in your code.
As always, we are more than happy to help out with tips and advice in this area, although we do not offer full script conversion services.

Lastly, when you install NinjaTrader 8, it's going to be a separate installation, meaning you'll have the capability of running both NinjaTrader 7 and NinjaTrader 8 side by side. When you first install NinjaTrader 8, you'll be asked to migrate your settings. To see what migrates, please see this link. You may also download and install NinjaTrader 8 from this link.
