Theta Data Reviews 6

I have been a customer of ThetaData for almost three years now and have watched the company grow and mature along the way. I am retired from the world of HFT/day trading options, but I'm still very interested in studying historical options data and how the markets behave.

The main thing that stands out is how ThetaData gives instant access to both real-time and historical OPRA data down to the millisecond level. OPRA is the SEC's public feed covering quotes and trades for over 1.5 million options symbols across 4,400+ stocks, ETFs, and indexes.

Back when I was actively trading, getting usable historical options data was a real hassle. It required an expensive live data subscription, maintaining banks of high-capacity hard drives to store everything, spending endless hours on programming to process it all, and handling way more set-up and ongoing maintenance than one person could keep up with consistently. ThetaData completely changes that. I can now pull exactly the data I need on demand in seconds with none of that heavy lifting or constant upkeep. It's an amazing accomplishment, especially for anyone doing research or back testing.

When I first started using ThetaData, I was blown away by the support from the developer/CEO, plus the active user community. Even as it has grown, customer service still feels like a top priority - right up there with the data quality itself. The developers and management are still very active in the Discord support channel, jumping in to answer everything from basic questions to really detailed technical stuff.

I highly recommend ThetaData to anyone who is serious about historical options data, whether for research, back testing, or just satisfying curiosity about the markets. It's made studying options history so much easier and more accessible.

Review the information provided carefully; otherwise, you will always end up needing more upgrades or services—a very deceitful way of offering services —and guess what: NO REFUNDS. So after a few days of you trying to figure out how to connect to their service and find out they are worthless, your money is gone.

Liked it! Managed to get everything in one place.

There is no competition when it comes to real time and historical options data.

As a seasoned trader, I have encountered numerous data providers over the years, but none has ever left such a lasting impression as Thetadata. This young, up-and-coming company has recently entered the options data provider scene with a powerful API that delivers history and live stream data. And let me tell you, their service is nothing short of revolutionary.

The first thing that struck me about Thetadata is the unparalleled completeness of their data. They provide literally every quote and transaction, ensuring that users have access to the most comprehensive dataset available. This level of detail has proven invaluable in refining my trading strategies and making better-informed decisions.

Thetadata's API is remarkably easy to use, with clear and concise documentation that makes integration a breeze. As someone who has dealt with cumbersome APIs in the past, I can't stress enough how refreshing it is to work with a provider that understands the value of simplicity and user-friendliness.

One might think that with such an extensive dataset, the performance would suffer, but Thetadata has managed to overcome this challenge with flying colors. The live stream data is delivered with lightning-fast speed, ensuring that I have access to the most up-to-date information as it unfolds in the market.

Despite being a young company, Thetadata's customer support is already top-notch. They are responsive, knowledgeable, and genuinely committed to helping users succeed. It is evident that this company is not only passionate about their product but also about fostering a strong and supportive community.

In conclusion, Thetadata has set a new benchmark in the world of options data providers. They have created an API that combines an astonishingly comprehensive dataset with ease of use, lightning-fast performance, and exceptional customer support. I have no doubt that Thetadata will make some serious waves in the industry, and I eagerly look forward to witnessing their continued growth and success. If you haven't already, do yourself a favor and check them out – you won't be disappointed.

I made the switch to ThetaData from Polygon after they throttled me despite advertising that they wouldn't. It took me an hour and a half to pull and process the same data from ThetaData that took me over six weeks with Polygon before they started throttling me.

ThetaData's customer service is superb; new features are often implemented and released quite quickly after a request, and the quality of the data is rock-solid.
