I'm thinking about subscribing to Prophetx - can you tell me how empty interval/periods are displayed? For example, overnight on Globex futures thinly traded minutes may not have any trades. Is a blank minute bar displayed or is is there no bar until some trades occur? ie. is the time axis linear?

Also on holidays, is there a blank bar or no bar displayed - or is it optional?

We do show a "blank" bar whenever no trades occur for a given time increment. So the time axis does remain constant.

On Holidays, we eliminate the blank from our charts, however that is optional and can be turned off.

I'm a new subscriber. I really like the daily and intraday holiday handling but on the cme emini 'ES' there seems to be an error:

There is a session break at 15.15 - 15.30 which is skipped correctly in the bar display but the 16.30 - 17.00 break is not skipped. Blank minute bars are appearing when they are not part of a trading session.

Also, is there a way to turn off 'dragging' completely on a chart? It is too easy when trying to adjust a line study to miss and drag the chart. This then messes up the auto scaling on the Y axis and I frequently have to reopen the Y axis properties and untick Minimum and Maximum (to restore auto scaling) along with reinputting custom Major Unit and Minor Unit options, which are also put out. (Much bigger grab points on line studies would also help.)

Last question, it is not critical but is there a way to have hourly bars start at the top of the hour rather than on the half hour?

You're correct about the session gap in the @ES intraday charts - I've opened a ticket to have the session hours adjusted to correct this.

Questions 2 and 3, unfortunately there is not a way to turn off the dragging feature in charts, nor is there a way to adjust the hourly bars.

Thanks. Please put the dragging issue on the request list. Also the bigger line grab points. I think the best way would be to activate dragging only by selecting/highlighting the data series - not just anywhere on the screen. And/or, it might be better if it only worked in the x-axis with the y-axis auto scaled. Or else just a tick box to make it optional.

Another bug:

Custom Y-scale properties get corrupted when saving and reopening a workbook, especially Major/Minor Unit (a great feature). But it's no big deal, I get by just using the default settings.

One more:

When 'fit data to chart' setting is selected and you make changes to the initial chart density, everything gets messed up and properties such as Right Margin lost, if you hit F2 to show/hide the chart toolbar. Part b) to this is I prefer not to use F2 but have to because the auto hide function is difficult to work and often the toolbar will not reappear no matter how long you hover the cursor in the right place.
