My NT8 is very slow starting up with indicators

[affilife]

I have 2 indicators loading at start up. It usually takes 10-15minutes to load everything up. During high volatility, it would take up to 30-40minutes to load. It's insanely slow. I have been dealing with this for months and to mitigate this issue, I open NT8 during night time and it takes like 5minutes to load. Still very slow. Without these indicators, it does not take much time. Can someone please help

Hello affilife

Thank you for reaching out.

Performance lag occurs in your charts when they try to print too much information at once and cannot keep up with the current price. This can become more prevalent in your charts during periods of high volatility and rapid market movement. Often, this is due to third party add-ins that are not represented efficiently on your charts.


First, I recommend you review our Performance Tips, which outline all the best methods for reliable NinjaTrader performance on any computer.

Be sure to install all available updates for your PC from the Windows Settings > Update & Security page. Manually check for updates here, and restart your PC after installing any.

*If you are using some third party add-ons; please note that we do not control how well they will perform and the more you ask NinjaTrader to load on your charts, the more it will put pressure on your PC which may result in freezing or laggy behavior. We cannot fix scripts imported from third parties.



*Some of the most common performance problems I have seen are related to having too many days loading on your charts; you can check the number of days to load with these steps:

- Right-click on a chart and select Data Series.

- In the "Time Frame" section reduce the number of days to load.

- Click OK to save changes and test.



**Another item that can overload your system is the method of calculating the indicators on your charts. Follow these steps to review/adjust the settings:

- Right-click on a chart and select Indicators.

- For each "configured" indicator in the lower left list, check the "Calculation" property on the right. Unless an indicator requires "On every tick", try changing to "On price change" or "On bar close", as these calculations consume fewer resources than "On every tick".

- Click OK to save the changes.


A test you can use to check the rendering delay is to open a SuperDOM window and compare that price to your chart prices. If the graphics prices update with a delay compared to the SuperDOM price, this is a telltale sign of rendering lag and indicates that you may need to lighten your workspace in order to adjust. We understand that this behavior can be frustrating, and is typically related to market movement and occurs at times of high volatility.


( You can also check which scripts are using the most resources by using the "NinjaScript Utilization Monitor".

Control Center > New > NinjaScript Output

Right-click inside the NinjaScript Output window > Select 'NinjaScript Utilization Monitor...'.

This window will begin to populate with NinjaScript items in order of processing time.

Let this window populate for at least a few minutes. You will then be able to see which NinjaScript, if any, is running at the top of the list and decide if you want to try to delete it).




*You can also clear old historical and cache data by doing the following:

- Shut down NinjaTrader 8

- Go to your computer's 'Documents/NinjaTrader 8/db' folder

- Delete the files inside the 'cache', 'day', 'minute', and 'tick' folders.

- Important: Do not remove any other files inside the NinjaTrader 8 Documents folder.

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

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