Solid Quote Solution for Options Trading We started using the Market Data (MD) OPTIONCHAIN formula to help speed up our quote time and delta calculations for our trading team. The amount of time we have saved by using this data has been extremely helpful to our team. We have opened several tickets since we first signed up for our annual subscription and the MD team has been very quick to respond to trouble tickets and to explain the features and limitations of the current MD solutions. We look forward to several of the new features that are currently under development on their company roadmap.

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.

So far we have had a great experience… So far we have had a great experience with the implementation. After having tried several data providers, this is the best by far. We cant wait for the News section to be available.

Professional and neat service Happy with Marketdata! Their team is super responsive and always there when I need help with data issues. They genuinely listen to feedback and keep adding cool new features. Plus, their prices are great for any account size. If you need reliable Stock and Options data, definitely give them a shot. I use their live and historical Option Chain API for my algo trading, and it's become essential for my Options trading. They're quick to make updates and always keep me in the loop. Highly recommended.
