Yesterday? I can see why your aggrieved. It's unfair to wait so long as it makes the seller position 100%. He sold because he was worried it would go down - obviously now he gets a 100% return.
No way...that trade settled long ago...time to change brokers and call the SEC...demand a copy from you broker and make copies of the tranaction from you account...
BURRP obv has a better handle on this than me. Just reading the basics the SEC says settlement is within 3 days. Wouldn't it have to be done and dusted by T+3?
I don't know if there's any exceptions to this. When that flash crash happened I thought it got sorted out for the next day?
