Version 7.17. One file with both add-ons: Lockout Sync and Emergency Flatten ALL. It needs NinjaTrader Desktop 8.1.8.2 or later, and it runs for the NinjaTrader account that holds your license — there is no key to paste.
The add-ons are licensed under the Lockout Sync for NinjaTrader Licence Terms.
You only do this once. After this install, new versions come to you inside NinjaTrader: Lockout Sync shows what's new, one click installs it, and you restart NinjaTrader to finish.
