DRL_Prediction for next day given only previous date possible?

[ecclessim]

I tried running the default tutorials for multiple stock trading and portfolio allocation. I noticed that for these tutorials, the prediction for trade is still given a set of information that is from the past to predict, the prediction never exceeds the last traded day. I am wondering, for example, today's date is 13/12/2021, is it possible to feed a trained agent an environment with only data from the previously traded day (12/12/2021), and output prediction for today 13/12/2021? Thank you.
