Assuming that my account is 200 MYR.
I am buying a 100 shares priced at RM2 (RM2*100 = RM200)
CIMB iTrade commissions = RM200*0.42%(in this case RM28, minimum brokerage fees)+RM20(stamp duty) = RM 48

HLeBroking commissions = RM200*0.1%(in this case RM8)+RM20 = RM 28

[I am not sure if the commissions are a round-trip commission or not]
My stock price has to move RM 0.24 for iTrade, and RM 0.14 for HLeBroking to break even.
In percentage, my stock has to move 12% for iTrade and 7% for HLeBroking.
They are significantly different.

I am using 200 to show how significant the commission is to low capital traders.
