Hi Engineering: I wanted to transfer my data file to a new machine; however, in the process, I discovered many SCID files that were in the gigabytes. Some did not appeared to have been modified for over a year or longer, as I've use different data services at times, so there were SCIDs from symbols & data feeds that I'm not currently using. I felt confident in deleting them. However, I immediately afterwards went to Data/Trade Service Settings, to check if this was due to incorrect settings on the Maximum Historical Intraday Days to Download... they read the default numbers, Non-Tick Data=186 & 1-Tick Data=186. I changed them to 31 & 5, respectively. I do not believe I need tick data further back than a few days. After what seemed a long download of historical data, I checked the folder afterwards, & once again I have several files that are over 1 gigabyte, numbering almost 8 gigabytes total (see attached image). Is this normal? Seems excessive, & might be affecting performance in addition to just using a lot of space on the drive. I have the Sierra Chart installation on a separate drive currently, & will eventually upgrade to a dedicated NVMe at some point. Nevertheless, by the time I cleaned up what seemed to be outdated symbols & instruments, I had eliminated well over 100 gigabytes of data, if I recall. This doesn't seem right. After restarting Sierra Chart & checking the new SCID's, still seems larger than maybe it needs to be. But perhaps everything is fine? Please advise. |
