It seems that font size, color and boldness should align with importance. Really important things should stand out more than less important things. Our eye should easily lock on to the important things.
That being said, please look at this screen shot.
I have one contract, but the quantity appears in a smaller font, is not bold, is not separated from the seven digit number that represents when I entered the position. Its just my opinion, but I think that a trader’s position is equally important to the average price of that position. Maybe the position quantity could stand out a bit more; separated by a space from the price, bolded, and the same font size as the average price.
