Post From: barchart dly files not always updating

Hi I've noticed over the last week or so that my historical data DLY files haven't always updated to the latest day when I launch SC in the morning. This isn't on every instrument, only some. The instrument where it came to my attention is VX futures but it isn't limited to that. I download the VX forward curve e.g. VXH26, VXHJ26, VXK26, etc and they didn't update this week. Last date in those files was Friday 23rd January. I've launched SC twice this week (in the morning UK time) and they didn't update. I've just forced an update now via "Download Data For All Historical Charts" - this worked. Any ideas why this might be happening on start-up? Trades have occurred in those contracts on the missing day (Monday 26th) so it wasn't because of 0 trades. I couldn't see anything suspicious in the log. I realise it might be to do with my setup, so for me to troubleshoot can you tell me how does SC keep those files up to date? After launch does it loop through each DLY file in the Data directory and update them 1 by 1? Or is it triggered by open historical charts? And while on this subject what time do the DLY files update in the evening for the current day? Is this an automatic update or does it need to be triggered manually via "Download Data For All Historical Charts"? |
