Marketdata is very good providing much needed data for a an affordable price. I believe there is still ongoing work with API's and bringing more data points on the way but it is definitely a great start and having OHLCV and OPRA data available at this price point is great. Keep up the good work. Their customer service is also impeccable, any request via tickets is answered within the hour.

Valuable service. I appreciate the google sheets integration. I get a lot of errors and have to refresh the sheet often to keep it working. Better than having to track manually but would appreciate a more stable feed.

The services offered are clear and well-defined, with excellent value for money. The online API documentation is detailed and very easy to understand; the endpoints perform well and the data is comprehensive. The support team responds promptly and responsibly. Highly recommended data service provider!

Install was easy, working very well. Quotes are bit delayed, but it is clearly mentioned.

In general, I like this service a lot but there is a number of issues. There are duplicate days in 2019, 2021, 2022, and 2023 that aren't trading days, so it makes it difficult to line up with Google Finance (which is what the extension is modeled after). There is also data that is wrong for 2008, 2009, and 2010 and has to be manually corrected.
Overall they have been responsive to correct errors in the past, but these errors persist. If the data was more reliable, it would be 5 stars from me

Good price point for retail investors. But it seems like no updates or new features that have been planned for several years

Very unclear how to use. Instructions are horrible. But once it is set up, it works very well. The only downside is the inability to have continuous, streaming, real time data, but understand that is due to some Google issue. I appreciate the suggestion of using the embedded Googlefinance function to make it automatically pull the data every 2 minutes. It would be great to have some mechanism to force that function to recalculate at whatever rate desired. Two minutes is too long.
Other than that, the functionality is very good. Just have to hunt around to find how it works. So, if there is a way to force the data refresh to 15 seconds instead of 2 minutes, that would be great.

Great extension! Tons of features for those looking to integrate market data into their sheets. Excellent customer support.

Reply from Market Data
Their pricing is very competitive and I really liked their free trial option, it is both long and offers a comfortable amount of requests to experiment with before buying.

Reply from Market Data
Well, your customers support before I got the license was great. Since I got the license I sent few email, no answer.
The package is good , however there are few annoying issues like the auto refresh of Google sheets data

MarketyData's API is a total "game changer" for me as an IA, allowing me to *quickly* make *better* buying and selling decisions for my clients. Their tech suport is also quick and helpful.

I use only the options data and I find it very useful and practical. I recommend, it saved me a lot of time.
It is great to have a well integrated app with G Sheets.

Reply from Market Data
I had good experience with the assistance provided. In order to solve a problem I ended up subscribing to a new 1 year subscription. Management kindly agreed to add to my new subscription the remaining time from my older subscription. That was fair. Thanks again for the help.

Good integration with Google sheets.
Able to access historical options contract prices.
Missing an easy way to lookup the option chain for historical option prices in Google sheets. Have to guess at the option strikes and lookup the expiration dates to assemble a valid symbol.
Large (200+) data requests from Sheets results in several with errors that have to be resubmitted to get a valid result.
Still a good product and value for the money.

I found a small glitch in a technical function and it was quickly repaired with personal attention.

MarketData.app is hands down one of the best services I’ve used for financial data. Their API is incredibly efficient and straightforward, making it seamless to integrate accurate market data into my trading algorithms and analysis tools. It’s fast, reliable, and offers extensive coverage of options, and more.
The real game-changer for me, however, is their Google Sheets extension. It’s perfect for those who want quick access to market data without needing to write complex code. With just a few formulas, I can download historical and real-time data directly into my spreadsheets, which saves me hours of manual work every week.
I also appreciate their customer-focused approach, with clear documentation, sample files to test before purchasing, and regular updates to their data sets—all included at no extra cost. MarketData.app truly understands the needs of traders and analysts, combining top-notch functionality with affordability.
Highly recommended for anyone looking for a reliable and versatile market data solution. Thank you, MarketData.app, for such an outstanding service!
