Post From: Data Date Range and Historic Download Issues

I understand. After I have tried several prior releases to see which one might be stable for my situation, the excessive data download has stopped occurring at some point in time on v2782. My process has been to remove all the data from the Data folder and try again. At this point, I'm not sure exactly when this 20yr download command stopped. Sorry, I wish I could give you a better metric but my focus has been on the VWAP study behavior since I use this extensively. Now, my biggest issue is with the VWAP study and trying to get a prior release to work correctly. I use the "stock" VWAP study that comes with each release. No other custom version or anything I cooked up. It's been working without issue for years until I updated to v2782. When the anchor date is set for the condition of Time Period set to Weekly, Monthly or when Ignore Time Period Type And Length is set to No and the anchor date is prior to Monday of the current week, for example the prior Friday - the deviation lines do not print before the bar on whenever time I start the chart. See the image of the 60min bar chart I uploaded. Look at that vertical line near the right edge - that's the "time" that I started SC and opened this chart and let it run over night. The deviation lines only print on each successive line after the chart was opened. This also happens on a historical daily bar chart. My thought was then to find that last version this anomaly didn't happen. My last attempt was to use v2773 since it has an improved NTP function (thank you, I like that), I can open the chartbook I uploaded for you with the one chart and one study and the deviation lines print as intended. If I try to open that same chartbook using my 60min chart which has many VWAP studies, SC locks up my computer (it's the only program running on my trading platform) usually somewhere around 99.6% of the data load on the 60min chart - I can see the box which indicates the data load progress. After waiting somewhere around an hour later, it's still froze in the same place. I then use Windows Task Manager to kill the program. I go back and download current version v2782 and the deviation lines are bunched up at the current bar but it loads. I then open my chartbook that has 10 charts and 3 custom spreadsheet studies, all the charts with the longest load time on the 60min chart (this has always been the case) and every chart that has a VWAP study of the condition I described above will not print the deviations lines prior to the current bar at start up. And to add insult to injury, I can open a new chart, add the "offending anchored VWAP" and it prints just fine. If I add a new VWAP study to any existing chart with the above conditions, it prints as designed as well. But if I Duplicate an existing VWAP study, it has the same print problem. Damn, I do not want to go back and rebuild all of my charts with these studies. At the beginning of my woes, this is what caused me to look at the data settings and look in the Data folder and discovered the excessive data download at that time. I haven't changed any of those settings and now it doesn't download all those prior data files (???!!!???) but the VWAP issue is persistent and reproducible as I have described. My thought is the VWAP study is the reason for these problems? And before I reached out to you, I looked at the What's New in the release notes and saw that you're working on a new VWAP of some kind - I don't need anything new. I also looked in the forum and found no one else making reference to my particular issue. Look, I know you get lots of requests from patrons who just don't seem to want to take the time to read your extensive documentation and then fuss at you (I'll just say it - lazy bastards lol). As an Engineer, I get it, people suck at reading and following instructions. That's not me. I sincerely appreciate your help. I am available over the weekend, but spotty at best. We're loaded up with end of summer social events. That being said, I'll keep an eye out for your response and do try to get back to you asap. Thanks, Todd |
