For my regular savings plan for the month of Jan 2015, I made 2 transactions on Monday.
1) I sold all my 800 units of Nikko STI ETF at $3.36
2) I bought 900 units of STI ETF at $3.36

On Monday, the lot size as reduced from 1000 to 100 units. This allows me to buy STI ETF as part of my rsp from now on. The 2 transactions are meant to convert my existing Nikko STI ETF to STI ETF. I have always preferred the STI ETF as it has a higher trade volume and lower expense ratio (cost).

Going forward, I will buy 100 units of STI ETF every month instead.

A summary of my current units are as follows:
