Market Data Opiniões 

A simple and straightforward api. A very responsive support team. Great value for money. I look forward to using their services for a long time.

IT is not updating in my spreadsheets and i got no response when I emailed the owner

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.

I like it. I prefer Google sheets so can build my own model instead of brokers models. As I have multiple accounts it is easy to combine. I was already using Google Finance formula but you have made my life easier. Now if only you can tell when to buy or sell!!!

Product does exactly what it says it’ll do and the team are very open to community roadmap development. Great.

Using MarketData has been a big timesaver for me regarding inputs of option prices and delta. I have experienced some inconsistent loading times and time exceeded errors.

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.

The many cool features it offers, especially regarding options and the Greeks.

This was just what I needed to get Options data. Works great. And get quick support answers.

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 start!
It could be much greater for service (and me) to obtain option greeks (I need Delta and Theta fervently) and to speedup API responses. Now I need to spend 900 sec to update my option prices once a day. I want to make it faster -)

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.
