Unless u're trading huge volumes, then the free commission makes sense. Otherwise the TD experience is pretty jarring or just so so tbh. The CS and the opening is very sub par at best from the many feedbacks. Plus withdrawals has fees.
At present using Tiger, interface is slick, live data, can trade pre and post market. Beautful app. Good support. Plus they team up with DBS so depositing and withdrawal is free if u're using one of DBS multicurrency acct (for USD) or normal SGD Acct (for SGD). Deposits are pretty fast within sg business hours. the exchange rates in app is not far off spot. And commission is though not free, but low and afforable (to think DBS charges $25 to enter the US market just 2 to 3 years ago is travesty, but one of the more widely taken options here due to DBS brand name and everyone's common bank)
Its how u value the Free commision fees versus the rest of the factors.
