You can use Interactive Brokers to trade Singapore stocks. It is the cheapest broker that I know of. The margin for borrowing Singapore dollars is also among one of the lowest ones. If I recall correctly, only Yen and Euro carry lower interest.
Foreign broker cannot be cheaper than domestic broker inside Singapore. Probably it is since two brokers charges together for connection charge. I like to know cheapest brokerage for domestic broker in Singapore, as well as their tax system (transaction tax or annual income tax?).
Furthermore, I would like to know brokerage comparison for many countries, such as Singapore, China,Philipines, ..... Of course best broker in each country too. PS) Like the interest comparison by each countries as shown in https://en.wikipedia.org/wiki/List_of_countries_by_central_bank_interest_rates , where is brokerage comparison by each countries?
Without googling the details, I remembered off the top of my head that Interactive Brokers was indeed the cheapest among all the available brokers. Cheaper than even the domestic brokers.
Under the hood of Singapore, where the engine usually resides, its downright ugly. Then go figure how much they boast about how well its managed, even its smaller than one's left toe? just one example: noticed the thousands of Filipino women sitting on the steps outside department stores and other big establishments, eating their food? They earn in Singapore dollars but cannot afford the eateries. And here's the kicker: these women have more heart, more soul, more smiles than all the native singaporean = robots on govt. subsidy and foreign b*itches combined I've seen. Disgusting God, why have you forsaken these people? I'm kind of mad at you http://factsanddetails.com/southeast-asia/Philippines/sub5_6g/entry-3921.html
