Is it bad to use uneven quantity of share. Eg: I want 1500$ of shares at $ 1.23? So I will buy Market or Limit for 1219 shares. (1500$/1.23=1219) Or other weird numbers. What Market makers thinks about that? TD Ameritrade ThinkOrSwim let you buy let's say 200$ of a stock and it will calculate for you how many share it make. It save me a lot of time and make my trading easier, because I don't want to trade more than a specific amount of money per stock. But I wonder what market maker thing of that? Any experience with that?
