It look like the promotion 0.1 % going to stay.. It have being like that for more than a year now.
I think our brokerage charges all round is not very high.. I don't see the reason why we should continue to look at the cheapest.
More important the system must have a high RAS ( Reliability , Accessibility and Serviceability). I rate CIMB is better than Maybank) since I could get my order through with less than 10 seconds before the close or opening. As for Maybank it usually takes more than 20 seconds. I can easily see this with the system side by side and I am using a very fast Unifi at home.

It is 0.1% ( initially charge at 0.42 and end of the month refund of 0.32) . I think there is a minimum charge on whichever higher...I don't have that problem yet as all my previous trades are of a sizeable blocks.
