Assume I were to invest $300 per month, I made a few simple comparisons :

1. Using Philip Share Builder Plan, I will incur cost of $6.42 every month
2. Using Standard Chartered Online Trading Platform, the cost is less than $1
3. DBS Vickers Online Trading : $25

Seems to me that Standard Chartered is the only viable option for small monthly investments?
