Hmm, what does that mean?
"most brokers don't finalize accounts until then"
Schwab StreetSmartEdge software brings down a menu selection box on a Sell trade and one of the "options" for "delivery" of the new symbol shares that aren"t in one's account is: "corporation event, i.e. Split," etc "Transfer Agent will deliver shares before Settlement" and you're eligible to place your Sell trade.
Settlement on todays trades would be in a few days (3).......
so I'm confused on the 20 days account "finalizing"
Help us out.
