When does exactly before_trading_start() get executed?

Dear Quantopians

Am I right that before_trading_start() gets executed right before any trading actions and at the earliest it is the very end of the 1st 1 min bar but it does not executed before the market open?

I guess it is executed at the end of the 1st tradable minute if trading is happening right from the 1st min and using handle_data()

Any feedback would be appreciated.

Best regards

Dmitry
