The quotation service has gone offline… The quotation service has gone offline several times throughout the trading session, at critical moments. I hope it's a one-off problem.

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.

It is a pleasure working with Market Data It's a pleasure working with a Company who cares about their product. Whenever I have issues with the data, their support gets back to me asap. They listen to their customers, and are constantly adding new features, with more in the works! They have very completive pricing, for all size accounts. I highly recommend giving them a try if your looking for Stock and Options data. Compatible with GSheets and Python.

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.

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.
