Time difference when loading charts

Same symbol, GBPAUD, building a 0.00350 range bars chart 1 month long for March 2019 takes almost 45 seconds, while building a 0.00350 range bars chart for the last 30 days takes less than 4 seconds. Why the time difference is so big? Can it always be as quick as the time needed for building charts with the recent (latest) data? |

The reason for what you are seeing is that the GBPAUD data is all stored in one file. Therefore, when you want data from some time in the past, the program has to open the file and search back to find that data and then get the data. Whereas when you just want the most recent data, the program can start at the end and just start loading the data going backwards until it gets to the stopping point. Faster drives can help. If you do not already have NVME drives, then consider them. Refer to the following: High CPU Usage | Inactive User Interface | Poor Performance | Long Time to Load Chart Data | Charts Reloading Often: 30.29 - Solid State Drives / SSD For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |

Yes, my SSD does not support NVMe. But can it be improved programmatically? My GBPAUD.scid file is 13 GB size, and I have a film 15 GB size. If I open the film and choose any timepoint on a seek bar, the palyer starts palying the film instantly, no matter how far this timepoint from the beginning. Why scid files aren't that fast? |

John, how big of a NVMe SSD drive would one need for Sierra Chart? Thanks |

We can not answer this question. There is a lot of programming behind movie players and the way the data is laid out. Could we do better - perhaps, but there are always going to be limitations.

This is really hard to say, as it depends on how much data you keep, the size of your charts and what is in them, along with how often you want to clean up the data files for Sierra Chart. You would just need to look at what your usage looks like today and make a judgement based on what you see.

OK, I’m computer illiterate, how do I find my usage? Do you mean the size of my Sierra Chart folder? Thanks |

Yes, exactly. The size of your Sierra Chart folder. Just open a File Explorer window and go to where you have your Sierra Chart installed to (typically this would be C:\). Then right click on the SierraChart folder and select Properties. This will show you the Size and Size on Disk. It would be best to use the larger value of those two.
