A simple, affordable way to invest

[CityFarmer]

There is a hidden transaction cost if you buy a non-SGD and choose to settle in SGD at a spot rate of the broker's choosing. It's probably much greater than your fees.

Do you know where can we find out about the exchange rate that the brokerage firm will charge before we enter into the trade?

You should be able to get the info, before trading, from your broker. The info may also be available online. I am using POEMS, which the info is available from the "Announcement" section in POEMS, online.

Hope it helps.
