Undecided on which brokerage to use for buying US stocks???

Check out this brokerage comparison table (https://plannerbee.co/best-trading-platforms/) and see the fees for US stocks. It appears that moomoo is the cheapest so far!

If you make frequent trades, going for a 0 commission broker like TD Ameritrade will save you a lot in the long run. They certainly do have a expensive withdrawal fee, but how often will you be withdrawing cash? It would be better to leave the money there and put it into investments rather than repeatedly depositing and withdrawing.

SIPC coverage is a plus for me, but not a deal breaker. IBKR (which is also Tiger's custodian) is very reputable and won't be folding anytime soon. IBKR LLC is covered under SIPC but its international subsidiaries are not.

Do note there may be some deal breakers for each of them. For IBKR, that could be the lack of free market data and minimum monthly commissions. For TD Ameritrade, they actively enforce the Pattern Day Trader rule which restricts you to a maximum of 3 round-trip trades within 5 days. And for Tiger, they are relatively new and may not seem as reputable as other brokers.
