Hi Jander,
Thanks,
The Y-axis of the volume pane is set in number of contracts, the default for the "MarginAboveBar" parameter is 1 contract. But if you want to see the gaussians drawn with some space above, you need to set a much higher number. Try 1000 contracts for the ES. This number is added to the real volume of the bar. If one volume bar has 20.000 contracts adding 1 or 10 contracts will not make the gaussian line very noticable, but if you add 1000 or 3000 you will see the difference.
