yup
if u buy onlive using pbb, the buying price is much lower than the publish rate

hopefully will go up next year above RM180

you calculate how much total cost you for each month
then divide the total to how much gram you bought to get even
you should sell only when the price is higher than the even price

eg:

on Jan, you bought 10gm, total = RM 1780
on Feb, you bought 10gm, total = RM 1680
on Mac, you bought 10 gm, total = RM 1580

so, total is RM5040 then RM 5040/30gm = RM168

Then, to get profit, you should only sell when bank bought at RM168/gm

hopefully UOB next to have the features
