I hope some issues regarding chart scaling are being addressed in the near future. Right now you are severely limited in eSignal. For instance, if I turn off auto-scaling (so that the chart doesn't automatically fill up the screen and in the process distort and exaggerate the size of the bars) all is fine.... until I change the timeframe of that chart, either manually or by using the favorites bar. In either case, the new timeframe always defaults to auto-scaling, and if I return to my previous timeframe it's been magically converted from manual scaling (as I set it and saved it) to auto-scaling. I'm sure this was implemented so customers wouldn't "lose" their charts, that is, not be able to find the prices which may be off the scale (until they drag the prices back into view), and in the process call and bug your tech support people. That's fine, but at least in your so-called Advanced Charts give those of us who want to permanently turn off auto-scaling the option.
Another issue regarding scaling is that you don't allow us to set the increments of the manual scale. That is, if I want 4 pts between ES scaling numbers (on the right of the chart) I can't do that. In fact my choices are severely limited and my only option is to drag an auto-scaled chart until it auto-resizes to something close to what I want, then turn off auto-scaling to "lock" it in. So for instance, with the ES I can drag and get the spacing to .50, 1.00, 2.50, 5.00 and then turn off auto-scaling. But those are my only choices!. So if I want 3 or 6 or 10, etc. then I'm SOL.
And another issue with how your scaling is implemented. Let's say I've turned off auto-scale and have it set for 2.50 (that is, the numbers on the right are spaced 2.50 increments apart). But now I want to see a bit more of the chart so I temporarily maximize it, or simply drag the sides of the window and make it larger. Somehow the program decides that the increment I set when I turned off auto-scale is no longer important (!), maybe the software feels that I didn't really mean it (!), and the chart magically rescales itself.
In short, whoever designed the scaling options of the charts in eSignal might have been a wonderful programmer, but they certainly were not traders.
