Solid Quote Solution for Options Trading We started using the Market Data (MD) OPTIONCHAIN formula to help speed up our quote time and delta calculations for our trading team. The amount of time we have saved by using this data has been extremely helpful to our team. We have opened several tickets since we first signed up for our annual subscription and the MD team has been very quick to respond to trouble tickets and to explain the features and limitations of the current MD solutions. We look forward to several of the new features that are currently under development on their company roadmap.

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.

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.
