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.

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

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.

5 stars because the tool is very useful… 5 stars because the tool is very useful and integrates with GSheets nicely. Without this tool, trading options would be far more difficult for me. The only downside is I find it a bit clunky to use because it lacks any kind of autorefresh function and the data does not persist--it seems I frequently need to manually request a refresh and it is unclear to me what sort of time limits are at play. The data it serves up are not persistent in the sheet so a manual refresh is required unless I manually copy the data and save it with a call to paste special/values only. These are minor gripes about a very useful app.

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.
