Unable to load instrument

[timmbbo]

Hi there, I'm unable to load instruments.

I just installed a new version of NT on a new machine. I've also copied over my replay and tick data to that machine. I want to load and replay the current YM market. I notice I can load it, as long as it's from 2017 and ealier. However, if I try to load from 2018 or newer, I get the error message of invalid instrument.

Your thougths? Thanks,

Hello rimmbbo,

Thank you for your post.

What is the complete error you are seeing?

Resetting your instruments should resolve this item.

To reset your instruments, please take the steps below.

1. First, disconnect from any data providers by navigating to the Control Center > Connections menu, and left-click on “disconnect” that appears to the right when hovering your mouse over any active connection
2. Next, reset your instruments by navigating to the Control Center > Tools > Database Management
3. In the Database Management window, under the “Update instruments” section, ensure that “General properties”, "Futures expiries" and “Symbol mappings” options are checked and then click Update
4. Lastly, restart NinjaTrader for the changes to occur
