Volume charts lagging

[RALight1983]

The past 2 days, I've experienced severe lagging on volume based charts, i.e volume bars, footprints, etc. The time based charts work fine and the 'last trade' price level works as it should. These charts have been fine in the past.

Hello RALight1983,

Thank you for the note.

From your description, it sounds like your platform is experiencing Rendering Delays on those charts.

• Tick based charts are more resource intensive than time based charts.

Rendering Delay occurs on your charts when they are trying to print too much information at once and cannot keep up with the current price.

• This may become more prevalent on your charts during periods of high volatility and fast market movement.
• You may also notice your orders filling immediately or being rejected as well as they are submitted to prices nowhere near the current market price.
• Oftentimes, this is being caused by 3rd-party add-ons that are not efficiently rendering on your charts.

To test for a price delay on your charts, compare the Last Price shown in your Chart to the Ask/Bid in the Chart Trader or the price of the same instrument in a SuperDOM window.

• If the prices match, this indicates you are not getting delayed data and that your chart is successfully showing live data.
• If the prices do not match, this indicates that your chart is experiencing rendering delay, meaning that it is printing too much information due to inefficient indicators or too many objects on your workspace.

If you confirm that your charts are falling behind the current market price, you may open the NinjaScript Utilization Monitor to see what (if any) NinjaScript items may be contributing to the symptoms:

• Control Center > New > NinjaScript Output
• Right-click within the NinjaScript output window > Select 'NinjaScript Utilization Monitor...
• This window will begin to populate with NinjaScript items in order of time spent processing
• Let this window populate for at least a few minutes
  • How to interpret the NinjaScript Utilization Monitor results to diagnose Rendering Delays
    • If you are still not sure of what the results indicate, take a screenshot of the Utilization Monitor and send the results in a response to this email

To Resolve the Rendering Delays:

• You will need to reduce the complexity of your workspace and remove things until it is able to keep up in real-time again
• If any indicators jumped to the top of the NinjaScript Utilization Monitor, then remove them from the workspace and see if performance improves
• If yes, then you will want to reach out to the developer of those add-ons and ask for further tips and suggestions on how to reduce their impact
• You could also create a new workspace from scratch while being aware of the Performance and also utilizing the Tips and Suggestions from the following Help Guide:

Is Ninjascript output available on Ninja Trader web? I'm not using the Ninja Trader desktop.

Hello RALight1983,

Thank you for the message.

No, there is no NinjaScript Output available on the Web Platform.

If the behavior continues, perform all of the follow tests:

• Refresh the Web Browser window then test
• Log out and back in then test
• Clear the Cache and Cookies from your web browser then test (If you don't want to lose saved passwords in other websites, you could skip this for now)
• Instead, open an "Incognito" tab within your web browser > Then sign in again and test
• Test a different web browser altoghether and test
• Disconnect your PC from the home WIFI and instead, connect it to your mobile hotspot, sign back into the web platform > Test again

If the behavior continues after all of the steps above, please send an email directly to Support[AT]NinjaTrader[DOT]com with pictures or a video of the behavior so we may investigate further:

• To send a screenshot with Windows 10 or newer I would recommend using the Windows Snipping Tool.
  • Click here for instructions
• Or, use the Video feature of the Windows Snipping tool to capture a short video instead:

Hello and respect,

If I want to add to Clayton's comprehensive explanation, which clearly and thoroughly covers all possible solutions, one common reason you might experience delays on the web-based platform is RAM usage when using a browser.

It doesn’t matter which browser you use—most browsers consume a significant amount of your system's RAM and resources. Please check your RAM usage in the Windows Task Manager while using the web-based platform.

Additionally, if you mention how much RAM your system has, we can assist you better.

Thank you!
