I have had some interaction with Zerodha's customer care and they sent me this info to enable the 'Link to Excel' facility. You do have to get in touch with them to get your self enabled though... The email which I received follows, and if you write to them, my presumption is you'll get the same info.
""First, you need to right click on your Market Watch on NOW exe and select 'Link to Excel'. In that option, you have to select 'All Items.'
Then you go to Excel and just do a paste or 'Ctrl+V'. This will enable streaming quotes on Excel.
Settings within Excel:
1. Open Excel - NOW supports Office 2007 and above.
2. Click the "Office Button" on the top left of your screen.
3. Click on "Excel Options" at the bottom of the new window.
4. In the new window, click on "Trust Center" on left-hand side menu bar.
5. On the right-hand side, please click on an option called "Trust Center Settings".
6. In the new window, click on "Trusted Locations".
7. Click on "Add new Location" on the bottom of the window.
8. Browse and select the "NOW" folder from your Program Files.
This will enable Excel to receive streaming quotes from NOW software.""
They ROB us through taxes & inflation & then use that money to pay idiots who shove their inane rules down our throats.
