Setup of New Excel Plugin with Velocity 2.0

Excel users have been facing issues of data lag in Excel if they add a large number of symbols. This has now been resolved.

We are glad to inform all our patrons, that we have recently launched a new Excel plugin along with a new Velocity 2.0 Plugin which fixes the issue of lag when using a large number of symbols in Excel.

NOTE: Before following the below steps, make sure your PC remains active all the time and it should not have Sleep mode active when idle, else, you would be required to restart Excel to start getting the Real-Time Data. Since, Excel stops pulling data from Velocity if PC goes in sleep mode.

Steps to check if your PC is on sleep mode or not > Open Control Panel > click on Power Options > click on Change Plan settings next to the selected plan as per the below image.

Now, select Never from the dropdown menu next to Turn off the display and Put the computer to sleep - as shown in the below image and click on Save Changes

This plugin includes the below-mentioned improvements:-

  • Removes all the lag in Excel even with a large number of symbols (say 250+)
  • Excel data updates smoothly even if you are using around 250+ symbols and also using Amibroker or NinjaTrader 7/8 simultaneously.
  • Even if you have added a large number of symbols, all data updates in Excel would be the latest updates at that time

You will need to follow the steps as shown below on how to set up this new TrueData Velocity 2.0 plugin with our new Excel plugin (excel plugin will work with Excel 2013 or higher versions only).

Step B14) If you have followed all the above steps correctly, the data would start to flow in your Excel Sheet, like so!

Info. 1) How the refresh rate in Excel works?

The default refresh rate of Excel is controlled by the RTD Throttle Interval In ExcelDefault Throttle Interval is 2 seconds (2000 milliseconds) - This means, Excel will update the Real-Time data after a minimum time of 2 seconds has elapsed from the last update. 

Info. 2) Why the Excel takes 2 seconds to update the data?

Excel checks the following, in the following sequence:

  • Is Excel Free? If yes then, check next
  • Is New Data available? If yes, then check next
  • Has the RTD Throttle Interval elapsed? If yes, then the rates would be get updated.

    (This means that if Excel is free & New Data is available but if the default time of 2 seconds has not elapsed, excel will not update the fields.)

Info. 3) How I can decrease the RTD Throttle Interval?

It is possible to decrease, this throttle interval from the Windows Registry if your PC is able to handle it.

However, if you use a large number of symbols, this could cause your Excel to crash as reducing the RTD Throttle setting could start loading your Excel excessively.

You can try reducing the RTD Throttle setting to up to 1 second, however, setting it below 1 second is not required and could also increase the load on Excel.

(If you find that your Excel is not able to handle the reduction in the RTD Throttle Interval, and is freezing or crashing, then you can revert to the same setting of 2000 ms (2 Seconds))

How to decrease Throttle Interval by less than 2 seconds - E.g. 1 second (1000 milliseconds) :

  • Note - Decreasing the throttle interval below 1 second is NOT RECOMMENDED! 
  • We would recommend this Step only if you have a very good computer configuration and wish to get faster updates.
  • Here, the Excel registry option has to be changed, wherein a new Key needs to be created and the Excel throttle interval will need to be manually reduced (default is 2000, we need to change it to 1000).
  • Search for Registry Editor (or regedit) from the search option on your PC and open it. (click on the image to make it large)

  •  Then visit this location > Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Excel\Options

  • The RTDThrottleInterval is not shown by default in the registry, you have to make this new Key. (click on the image to make it large)

  • Just right click > New > QWORD (64-bit) value (if you have a 64-bit Excel) and give name as > RTDThrottleInterval

  • Now, right-click on RTDThrottleInterval > click on > Modify... (click on the image to make it large)

  • Now, select Base as > Decimal > enter Value Data as 1000 > then click on OK and close the Registry Editor.

  • After following all the above processes start/restart Excel & Velocity once to get the changes implemented.
