Which broker is most suitable for US and HK stocks?

For US, you may wish to consider thinkorswim: https://www.tdameritrade.com.sg/tdaa/index.html

Here is everything about me and what I do best.

I receommend Interactive Broker, another one is think or swim platform of TD Ameritrade. They have one of the lowest brokerage rates for comission and platform fees​​​

Interactive Broker is very cheap, with the lowest fee in the world (probably) and the widest range of products.

They are known as mass-market stock brokers.

If you are doing only $100 a month, it can still be cheaper in IB despite the $10 monthly fee by IB, if your stock is bought in overseas currency. This is because IB's forex rate is hugely with no hidden spreads in some banks and brokers. You're saving quite a big difference in the forex.

1. The commission is the lowest. (some products are negative commission, means you get paid to trade). Most of my commission is $1 or $2 for 100 stocks. And I get paid commission for trading in non-popular stocks as I adding liquidity to them.

2. Variety is the widest in this broker.

3. Forex rate is one of the most competitive (a lot of brokers have hidden fees due to the spread)

4. They have a local Citibank account, so you can FAST transfer SGD, and the SGD reflected in your account within minutes. Then go platform and exchange to USD or whatever you want on your own.

5. $10 minimum fee, so if you only trade $4 this month, they will charge extra $6 to round it up to $10.

5 is a bad point, but 1-4 makes it worthwhile.

Interactive Brokers too! :)

Jia you for your investment! It's going a journey of constant learning! :)
