Screen stocks with 1 million volume during pre-market

Hello Amibroker Wizards,
First, I'd like to say thank you for all your help.

Second, I'd like to ask a little favor from all of you, if you can please help me how to screen stocks with a Pre-Market volume using Amibroker.

For example: I want to screen stocks with a 1 million volume during the first 30minutes before the market opens.

Thank you so much in advance! :kissing_heart:

Please... anyone? thanks
