Definitely new to the day trading game. I had a couple of stocks preform really well and decided to sell yesterday. I got notification of the sell being completed this morning. My buying power shows the new amount but the amount transferable is the same for last couple of months. Is there a built in delay that I’m unaware of?

From my experience it takes a few days for the “final” notification, however, it stay at the same sell/buy price.

Takes 2 days from trade execution until settlement per SEC. Commonly referred to as T2.

Yep, two days to settle the funds. You can still trade with those funds. But can only transfer settled funds.
Also I recommend learning the difference in day trading and other trading. Don't get marked as a pattern day trader with less than 25k in your account. You will find your account locked for 90 days.

Open an account with a real broker and not a fischer price broker.

The standard settlement for an equity trade is T (trade date) plus 2 (days). This means the trade settles 2 days after the trade date. It was T plus 3 until a few years ago. You can probably buy something else that would settle on or after the current settlement. It won’t let you get the cash out until after the trade settles.

If you really want your head to spin, look up how Robin Hood gets paid for order flow. Trades are not “free” there.

Is it merely a coincidence that the day the sell is final, every time I try to log in I get "something went wrong"?

Robinhood is one of my four accounts. It serves its purpose that I use it for. But there are definitely better ones out there. After their last couple of stunts. I keep my funds fairly low in that account. I use it mainly for quick swing trades and if I want to burn a day trade.

Robinhood is a complete joke of a platform.

The coincidence isn't because you have settled funds. Its because both Gamestop and AMC are doing their thing again.

Thanks for clarification Rick. I guess I sold my AMC too soon....

Still time the squeeze hasn't squoze yet.

T+1 is on the immediate horizon...which will make life a little cushier.

I wonder if that will change the PDT rules

The settlement timeline is fairly common to all brokers, but you should get with Fidelity or TD Ameritrade. Robin Hood pulled some shady stunts last month and needs to be bankrupted - they're awful.
