I wire money in early am sometimes few hrs after midnight, it registers bye opening bell, been really nice, they must have me on their radar now and see me coming i use TD, been better as of recent and on time.depends on who you use and an ach deposit could take as long as 3 days sometimes, link your broker acct to you bank acct, sending money back to you bank is fast also 1 day usually..and usually a margin acct over $2k is beneficial for that also. your funds are always available when you sell a security that minute.
