Great Product, Super Service 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.

So far we have had a great experience… So far we have had a great experience with the implementation. After having tried several data providers, this is the best by far. We cant wait for the News section to be available.

Customer service is very responsive and… Customer service is very responsive and answered all my questions.

Good and simple Good and simple. Does what it says it does and does it well. Missing some seemingly obvious features such as being able to get a list of supported exchanges and codes on the API end points. Looking forward to them. Good support. Signed up. Will keep using them.

Great add-on for google sheets 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.
