Zack Earnings Surprises in Handle_Data function

Hello,
I want to run a daily report with the handle_data function that combine prices of different dates as well as other information of the stock such as market cap, sector etc.
Likewise, I want to combine this public information with the Zack Earnging Surprises dataset to conduct analysis of the changes in the earngings over time and their deviations respect what is estimated. I view that Zack Eerning Surprise dataset and have usefull information for this purpose. Finally I want to make a rank with the biggest loss after the earnging announcement thake place.

I try to use pepilene with before_trading_start funcion, but show me information of past days.
What if I use the handle_data function? Is possible to combine all this data inside the handle_data function and run reports daily?

Some help would be very appreciate!
Thanks
Nicolás
