I don't know about TDW specifically, but some brokers allow you to overdraw your account because you're allowed 3 days to send them the money. One of my brokers where I have a margin account makes most orders go through a manual approval process once you go over your overnight buying power, yet they still never denied me a trade and even let me go over my daytrading buying power once, though this was never indicated on the platform - I didn't know until the next day, when I discovered my buying power was down to 2x.Quote from jck_2378:
TD waterhouse allowed the intruder to overdraft my cash account to an amount of negative $150,000, all used to buy WOLV stock. My cash balance after this fraud then showed negative -$150,000, is this normal for a cash account?
