Which do you think should be the standard for expressing comissions I have heard the following ways 1) 5.50 / 1000 shares 2) .55 / 100 shares 3) .0055 / share Personally I think #2 is the best way to express comissions. #1 gets tricky when you have the "five dollars and fifty cents" #3 kinda gets tricky point zero zero five five---> our minds don't really think in decimals. #2 in nice. Fifity five cents per 100.
