Resolution Volume Profile

[Joseph_76]

Good morning,
I have to load 800 days of Volume Profile, with tick resolution the PC freezes, with minute resolution I can load it, what is the technical difference between tick resolution and minute resolution?
Thank you.

Hello Joseph_76,

Thank you for your inquiry.

Ticks are the most granular forms of trade data the platform can request.

Tick charts show trading information as trades occur. One-minute charts show prices in one-minute intervals if there is a trade, uniformly creating a chart.

You may read a full overview of how charts are built in real-time here in our NinjaTrader 8 Help Guide - Charting > How Bars Are Built


To load 1 day of tick data requires much larger files than loading 1 day of minute data, so it is no surprise that attempting to load that much data would push the platform and your PC resources to their limits.

If you have to load that many days, then I would suggest limiting the amount of charts in the workspace that are requesting that kind of data.


I highly recommend going through our Performance Tips, which outline all the best methods for reliable performance from NinjaTrader on any computer.

Be sure to install all available updates for your PC from the Windows Settings > Update and Security page as well. Manually check for updates here, and reboot your PC after any are installed.

If you are using 3rd party add-ons, Please keep in mind that we do not control how well they will perform and that the more you ask of NinjaTrader to load on your charts, the more it pushes your PC which may result in freezing or lagging behavior.

Some of the most common items with performance/loading I have seen, are related to having too many days loading on your charts; you may review the number of days to load with these steps:

• Right-click a chart and select Data Series
• In the "Time Frame" section reduce the number of days to load
• Click OK to save your changes and test

Another item that can place a heavier load on your system is the method of calculation for indicators on your charts. Use these steps to review/adjust the configuration:

• Right-click a chart and select Indicators
• For each "configured" indicator on the bottom left-hand list, double-check the "Calculation" property to the right. Unless an indicator requires On Each Tick, please try changing to On Price Change or On Bar Close as these calculations are less resource-intensive than On Each Tick
• Click OK to save any changes

You may also clear old historical and cache data that you do not need by doing the following:

• Shut down NinjaTrader 8
• Go to the 'Documents/NinjaTrader 8/db' folder on your computer
• Remove the unwanted files within the 'cache', 'day', 'minute', and 'tick' folders
• Important: Do not remove any other files within the NinjaTrader 8 Documents folder

When you restart NinjaTrader 8, you may notice a slightly longer initial load time as all historical data on your charts is re-downloaded, but your overall performance should be better.

Please let us know if we may be of further assistance or if you continue to experience this behavior.
