Post From: Horizontal time labels, vertical grid, and a bug

1) I would like a way for the time labels on the horizontal scale to line up exactly with the vertical grid lines. Currently they are completely unrelated, which is confusing. Background info: Unless I'm missing something, Sierra currently gives me excellent, wonderful control of the vertical scale, but no control of the horizontal time scale at all. I use "number-of-trades-per-bar" intraday charts (aka "tick charts"). I set "Vertical Grid Lines" to display every n minutes. This is excellent! Although my charts are tick-based, the minute-based vertical grid lines tell me how quickly the market is moving. When the market's moving fast, the grid lines are far apart; when it slows down, the grid lines are closer together. It's a great, intuitive visual cue. I'd just like to be able to quickly glance down to the bottom of a vertical grid line and see the corresponding time! I think the simplest solution would be an option: "Align time scale with vertical grid". This would work for me. The more flexible solution would be a "Time Scale Increment" setting, analogous to "Scale Settings/Scale Increment" on the vertical scale. During slow periods, like night session, the vertical grid lines can be very close together. If a new time label on the horizontal scale would overlap the previous label, it should just be skipped. 2) There is a small but annoying bug in the vertical grid line logic. On a 22-tick NQ chart, set to show a vertical grid line every 1 minute, every once in a while a duplicate line appears - two vertical grid lines are displayed on adjacent bars that are only a few seconds apart. As far as I can tell, this only happens when the first bar starts on an exact minute boundary with .000 milliseconds. For example, with Vertical Grid Lines set to display every 1 minute, I see a line, correctly, when a bar paints at 9:33:00.000. But then another grid line appears, incorrectly, on the next bar at 9:33:01.016. Another case is 9:53:00.000 and 9:53:04.002. In every case I've checked, the first line shows at .000 milliseconds - the logic for the next bar is not recognizing that the line for that minute has already printed on the .000 bar. Here's an example, with lines at 10:24:00.000 and 10:24:00.022: http://www.sierrachart.com/image.php?Image=1494788824591.png (This image also demonstrates the random relationship between the vertical grid and the time labels.) 3) If I have unchecked the option "Include Seconds on Intraday Chart Timescal" (Advanced Settings 3 - and yes there's a typo on "Timescal"e :-) ), then I only want to see a time label for each new minute. Currently, on my fastest chart, I see a string of duplicate labels like: "9:30 9:30 9:30 9:30 9:30 9:31 9:31 ..." I'd rather just see: "9:30 ___(open space)_______ 9:31 _____ ..." I'm trying to simplify my charts as much as possible. (In my case, fixing #1 would automatically fix #3) Thanks, Merlin Date Time Of Last Edit: 2017-05-14 20:29:42
