TD Ameritrade Cash Alternatives I've been a trader for just under two months, making a few trades but just recently I sold a stock and instead of the money being available to trade, it went to cash alternatives. Now through my 5 minutes of googling I found out the money will settle in 3 days and all will be good. But I was wondering why it happened to this trade specifically and not my other trades? Some things to note about this trade: I was using money that I just put into the account like maybe a day ago, also I used substantially more money than my previous trades. Does some of these factor in to why my money went into cash alternatives?
