edster1, I have a question about Ameritrade.
If I have 10,000 shares of NEOM and that's all I have in Ameritrade account. I sell ALL of it at $0.5, then I should have $0 cash but $5000 unsettled fund. Suppose NEOM drops to 0.45 ON THE SAME DAY, can I buy all 10,000 shares back ON THE SAME DAY before it is settled? I mean, do I need margin account for this? OR if I have margin account, how much do they allow you to use to buy it back(especially for OTC stocks like NEOM. do they allow it on OTC stocks)? Thansk a lot.
