If you track your option trades on your google sheets this is a must have add-on. You get realtime options prices within your google sheets just like googlefinance so you can automate your strategies and program your sheet to send alerts for entering/exiting trades without even having the trading platform on.

Thank you for your review. We appreciate it.
Great start! It could be much greater for service (and me) to obtain option greeks (I need Delta and Theta fervently) and to speedup API responses. Now I need to spend 900 sec to update my option prices once a day. I want to make it faster -)

Thank you for your review. Greeks are coming soon.
I have nothing but positive things to say about Marketdata. They have been responsive and answered my questions in a timely way. They are still building out the product ( I use the Google Plug In) and if I find anything they are quick to update and advise me. This has become an integral part of my Options trading workflow. Highly recommended.
