    Slow chart loading speed

    I only trade 2 different products. The only thing new on my chart every day is the new day, yet it still seems to spend 15 minutes loading the 365 days like it's the first time.... I would think that data would be cached away for the next time NT8 is opened?

    Hello DoubleR,

    Thank you for writing in.

    We have split your question into a new forum thread as the fundamental question is different.

    The time it takes to load in your chart will change depending on how the underlying data series is set up along with what indicators are on there and how they are set up as well.

    Please read through the following help guide article that goes over how charts are loaded in detail, expand each section and read for additional information:
    • https://ninjatrader.com/support/helpGuides/nt8/loading_historical_data.htm
    So, parts of the information will be cached while others will not. As well, if you have any Tick based indicators or charts, those are inherently going to take longer to load in as they can include numerous more data points than a time based chart and their calculations can take longer.
    • For example, a 1 minute bar is always just going to be 1 data point
    • But, within that 1 minute, 10 ticks could have happened or 10,000 ticks could have happened
      • So, Tick based things normally take longer to load due to the increased number of data points in the calculations

    If it is taking 15 minutes to load the workspace, this hints that it is a complex workspace with some calculation intensive things going on inside.
    • I suggest reading through the following help guide article and then going through and optimizing the workspace with the various tips and suggestions and see how its performance changes:
      • https://ninjatrader.com/support/helpGuides/nt8/performance_tips2.htm
    • You could also create a new workspace from scratch and then add things back in 1-by-1 and then restart NinjaTrader and see how each thing affects the load time. Once you narrow in on what is causing the longer loading times, you can reach out to the developer for more information on what settings you could modify to speed things up.
    Please let us know if we may provide any further assistance.
