How do I exit my position and prevent buying outside of intraday time frame?

[brettcomardelle93]

Yesterday I was charged $50 fee because my strategy entered a position at 3:59PM. This wasn't because buying conditions were met though. This entry happened with "Exit on Session Close" which my strategy had enabled.

I had a position and then an external close happened. I don't know why this happened.
Then, on the session close, it entered a position instead of exiting.
External immediately closed that.

I'm not entirely sure why this all happened, so explanation would be nice. But, how do I prevent this and just exit at 3:45, like that first exit which was "external". I dont want this fee to happen again.
My guess was to just disable the "exit on session close" and let the external close happen. My assumption is that this close came from the broker.

Hello brettcomardelle93,

External orders are orders that were not submitted from NinjaTrader. These could be from another computer or submitted by your broker.
Contact your broker to inquire about the Order Id numbers of the orders you to see marked as External in NinjaTrader.

The 'Exit on session close' and 'Exit on session close seconds'are settings in the Strategy parameters window that will automatically close any position opened by that instance of the strategy at the specified number of seconds before the end of the trading hours seconds.

Uncheck Exit on session close if you do not want the position closed at the end of the session.

In code these are set with:
