Account Settings
After an account is added to the Account Manager, you have the option to Edit/Enable a Monitor or modify account-specific settings.
Tradovate monitors have their own Account Settings tab holding the account nickname, the auto-flatten time, and the Block Signals and Closing Only switches. Trading windows are not among them, since those are a NinjaTrader 8 feature. See Tradovate Account Manager.
Click on the Pencil ✏️ icon in the Actions column and then click on the Account Settings tab at the top of the config window.
Inside of the Account Settings window, you have the option to set an Auto-Flatten time or add up to 5 distinct trading windows.

Trade Windows will be evaluated regardless of whether or not the Monitor is running/enabled.
Auto-Flatten will only execute if the Monitor is enabled.
