Very good customer service. Quite happy with the company.

It works but the data is not particularly fast, needing to run the sidebar to receive quotes is a bit annoying, no automatic refresh intervals, and no support for international securities.

Title: Precision, Depth, and Reliability — A Game-Changer for Our Data Needs Review: We've been incredibly impressed with our experience using MarketData. The level of detail and historical depth in the data has been nothing short of exceptional. For our use case—where precision, cadence, and continuity matter—the platform delivered exactly what we needed. What stood out most was the consistency and clarity of the data. Whether we were pulling historical open interest, volume, or minute-level aggregates, the results were clean, reliable, and easy to integrate into our analytical workflows. The API structure is intuitive, and the documentation made onboarding seamless. MarketData has become a cornerstone of our diagnostic overlays and rhythm-aware dashboards. It’s rare to find a data provider that balances granularity with accessibility so well. We’re grateful for the transparency, the responsiveness of the platform, and the sense that this tool was built with serious analysts in mind. Highly recommended for anyone who values data integrity, historical reach, and technical elegance.

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.
Response from Market DataNov 10, 2025

That said, we completely understand how frustrating frequent errors and the need to manually refresh can be. We're actively working on improving the stability and responsiveness of the feed, and your feedback is an important part of that process.
