Could you please clarify what the minimum amount required for opening an account or initiating a trade on TradeStation is? I'm interested in getting started with this platform but want to ensure I meet any initial financial thresholds. Is there a specific dollar amount that I need to deposit, or is it dependent on the type of trading I intend to engage in? Additionally, are there any fees associated with maintaining a balance below a certain threshold? I appreciate your help in providing this information.
