hi guys,
i'm a bit confused with the preference on whether to use SCB or IB for buying IWDA (or foreign ETFs). background is i'm thinking of DCA with SGD1,500 monthly, rotating between the three ETFs in the 3-ETF portfolio each month.
so for SCB they have lower commissions, while for IB the biggest disadvantage is due to the USD$100,000 'fall-below charge' (i'm not expecting to hit USD$100,000 in decades as i'm likely to use IB only for foreign stocks)? however i have seen comments that IB has more favourable fx spread which may negate the disadvantage, is this something i can assess by visiting their 'charges' page in their website, or is a 'do it to know it' thing?
