- without dividing the change in price by points, you are left with some decimal number of the ask/bid change, say 0.003, this is being typecasted into an integer via int(0.003), which turns it to 0, and 0 is plotted, without typecasting the decimal will still be cut into in an integer and a compiler warning telling u its happening will show up - if you want 0.003 instead of 3points, you can turn the variable delta_ask/bid into a double instead
Thanks jeanlouie
