Like the rest services but... Like the rest services, performance can be a little slow

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.

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.

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.

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.
