If you trade stocks, several stocks in one day, how can you do that if?

Question

the sale doesn't official record until the next buisiness day? Or when does the sale of the stock officially occur after the order to sell is placed?

How can anyone do day trading quickly and in a timely manner?

Answer 1

You can trade several stock in a given day, you should  have the money in the account when you enter the order.

All purchases must be paid in full before they can be sold, and you can not use the proceeds of the sale to pay for the purchase.   If you sell before you pay for the purchase, your account is restricted for 90 days or until payment for the purchase in recived in full.  

All trades settle in three business days.  There is the day the trade is made (trade date) and the day the trade settles (settlement date).  The settlement date is 3 business days after the trade date.

All broker/dealers maintain their books and records as of the settlement day.

If you're going to day trade you should have sufficient monies in your account to cover all purchases.

You could also have a margin account as day trader, but you must maintain equity of 25,000 at all times.  Judging by your question, this is not for you

Answer 2

leave all of that to your brokerage firm?

Answer 3

Stock trades settle 3 business days after the trade.  Mutual funds or options settle the next business day.

In order to day trade, you need the cash in or already settled in your account before you buy in a cash account, or enough margin in a margin account.

In the U.S. to daytrade more than 3 times in 5 business days, you need a margin account with at least $25,000 in assets (SEC pattern day trader rules).  Note that if you hold a stock until at least the following day, it is not considered daytrading for those rules.

There are also "free ride" or "good faith" rules.  If you break the rules too often, you may not be able to trade anything for 90 days.
