Please help confirm or correct my understanding!

Hi everyone,

In traditional RL, every step consists of (S, A -> S', R), but in the context of FinRL, an action taken, i.e., buy or sell at whatever quantity, does NOT transfer one state to another, i.e., that an agent takes an action does not result in a price change from today to tomorrow.
If so, how should we calculate or estimate the price at every step?

Btw, is ElegantRL functioning perfectly just like SB3?

Please help confirm or correct me!

Thanx.
