# RTD: Setting Excel throttle limits

Excel automatically limits the rate at which it checks for updates. By default, it sets the throttling rate to 2000 milliseconds (2 seconds). In a fast-paced trading environment, such an update might not be sufficient. TT recommends that you disable the default Excel throttling rate by setting its value to 0. With this value, Excel continuously checks for updates, ensuring that you have accurate and up-to-date values.

To set the throttle interval through the Excel object model:

1. In Excel, open the Visual Basic Editor.

2. In the Immediate window (press CTRL+G or click Immediate Window on the View menu), type this code: Application.RTD.ThrottleInterval = 0, and then press ENTER.
3. To verify that it is set correctly, type this line of if code in the Immediate window: ? Application.RTD.ThrottleInterval and press ENTER.
