I've just started to use MarketData I've just started to use MarketData. I finished the first version of a Windows App that lets me gather and analize option chains and stock info. So far so good. Servers have been up with no hiccups and my Application is running well with the API calls. I would have given five stars but was disappointed that dividend data on stocks wasn't present. Dividend is a pretty standard metric. So I hope it is added soon.

Why not show on the menu when the last… Why not show on the menu when the last update occurred. Thad would help manage the refreshments of my data more easily.

Reliable and inexpensive Quotes are reliable and service is inexpensive. Option quotes via an API are hard to come by so that's a plus for this service. A few quirks here and there with the Google Sheets but my Python program is quite happy being able to get quotes without having to scrape an unreliable web page.

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.
