For ocbc securities, each trade is $25 means buy is $25 and sell also $25? And how do they credit dividends? Straight to your bank? Dividends also have to pay commissions right?

Yes. buy $25 comms. sell also $25 comms.

dividends straight go into bank account. it should be the same account used for deducting the stock transactions.

no dividend charges for SGX listed stocks and the dividend is also in S$. there will be a currency exchange fee if it is in another currency.

the above applies to SGX listed stocks.

other charges apply for non-SGX listed stocks.

hope this helps​​​
