What I like Singapore Oanda

Fund may be held in SGD, unlike many international online forex brokers that require them to be converted into U.S. dollars (or other foreign currencies) of funding. This makes sense as a good money now SGD is expected to strengthen against the USD

Batch split, more flexible fixing micro, mini or standard long-only. This will allow a better position, size (risk management)

The interest is given to the unused funds. Although the interest is minimal, is better than nothing

Aversion

Interest charges (roll-over) are imposed in proportion to immediate, unlike most agents who are paid daily. Day-traders/scalpers a slight disadvantage if you are in the negative lateral shift
