Anyone know the cheapest way to buy US stocks in Singapore?

TD Ameritrade is excellent, their fee for U.S. stock/ETF trades

is 0.00 USD (since 10/2019).

Guys the cheapest way is free brokerages like firstrade.com or robinhood.com

if the question is what is the CHEAPEST, TD IBKR cannot beat FREE trades.

There are downsides. eg. maybe not as fast. cannot do charting. no analyst reports.

but free is free.

A friend recommended me Jitta ( https://www.jitta.com/ ) to study the US market. They have their own proprietary scoring system (Jitta Line and Jitta Score) to determine if the stock is worth investing or not. Their scoring system was inspired by Value Investing strategy, which is to buy a wonderful company at a fair price.

Buy your US counters from TD or IB. It is very easy to set up an account and it is pretty safe.

I will recommend you to watch their news live, like CNBC/CNN to get the latest news. You should be trading US market while watching/reading their latest news as you are not in USA, you might miss certain news that might impact your counters/market.
