@Inner Yo：Am I misinterpreting what this is saying?

When you call during off-market hours Eastern Time, a recording tells you that no one is available but for during market hours.

All that is left is the AI bot customer service window and no help files on point to my question.

Specifically, why a buy order indicates that it is buying on margin when I have more (“withdrawable”) cash than the order placed in the account?
