It really depends on your brokerage
Im not going sit and say all brokerage settle in one day When i first started.... a NEWBIE
I had this local brokerage and they take forever to clear and settle
Almost 5 days.... or more sometimes

The tech as gotten good though
Its really up to your brokerage
And how good and how much cash they have
Sometimes they will just lend you money in advance ROBINHOOD does this
I still have no idea why that kid who kill himself
...have acess to $700k++whatever
