I'm trying to understand what is causing the big changes with the space left on C: (where sierra is located) for example before running sierra (fresh after a reboot) I have around 10GB available - after running it and while it loads the date files it can drop almost to 1GB available space it can raise up and the free space is between 2-4 or something while sierra is active. If I reboot the pc again its back to the original 10GB size - what is causing it to drop that much? if the size on disk size of the scid files are about 1/4 of the actual file does it mean it loads it to maximum on each scid file that is used (I'm using continues contracts)? and if so why is the space left available after closing sierra is around 2-6GB is it related maybe to pagefile? I've limited the 1 tick data to half of what it was and also reduced the number days of the heavier charts that are loading so that I won't get to 0 space since it got to a point that 7GB are not enough for that load (which used to be ok for a long time) thank you |

thank you but its directly related to Sierra and its not a small thing If I just had to restore a backup since I got to 0 space left - and it also affects other programs running cause when u get to 0 left nothing is saved and so no configuration is saved on any program running. It doesn't happen with other programs so I'm asking to understand better how can I prevent my pc from getting to 0 space while using Sierra. "Sierra Chart intraday data and market depth files take the most amount of space but they only increase in size. They do not go up and down in size." - It means that if I run it and download new data that is the only thing that's downloaded? if so how is it getting from 10GB to almost zero within 1-2 minutes of loading the charts? I'm sure I'm not the only one has it so its a major problem to understand |

Add a 256 GB SSD drive (under $100) and dedicate it to Sierra Chart.

How much RAM do you have? How much is in use when SC is running? If you are low on RAM, Windows will page a lot and your paging file will increase and fluctuate which can cause issues. Make sure you set your paging file to a fixed amount.

Make sure you set your paging file to a fixed amount. Yes we were thinking later this is actually what is probably going on in this users case.Not only this, but the operating system can cache the intraday data as it is being read from the data files and that will cause a significant increase in memory, and if there is not enough system memory, then it goes to the paging file.

I was suspecting the page file is causing it and it is, I have 8GB of RAM, with SSD Drive but not a lot left on C: (if there's 9GB free it's not getting to the point of zero but might get closely) - If someone is experiencing it reducing the number of days of maximum tick data helps and also loading the bigger charts with less days (for example I had 360 days of 4h chart and reduced it to 240). Now the problem was also reducing it since the charts are getting loaded automatically when launching Sierra and at the first minutes of loading the CPU is almost on 100 constantly so just do disconnect whenever possible (that prevents the massive loading) before it gets to zero space left and then change the max historical etc. |

An SSD will slow down if it gets close to full. I suggest removing files and/or applications you don't need. Run Disk Cleanup to remove temp and other unneeded files that tend to build up over time. If you have adjusted the number of days or the Intraday Data Storage Time Unit, then you can delete old SCID files. They will not be removed automatically. You could delete them all, and just let Sierra redownload the ones it needs when you open the chart. Or you can do it manually based on the contract name/date. If you are trading Forex or Equities, the files will keep growing in size instead of a new one being created during futures rollover. Then the best choice is to just delete them and Sierra will only download as far back as your settings specify. If you don't need all the charts loaded at startup, then turn off remove or disable automatic File loading in the Global Settings>>General Settings window. |

yeah I've already removed anything possible and most of the SCIDs, I think due to the massive load and almost 100% CPU constantly on the first minutes of loading Sierra windows moves a lot of data to the pagefile and after the overload is over and historical data and charts are loaded I get few GB back from the pagefile thanks a lot for the quality advises! |
