Have been using QC for 3 years Have been using QC as an individual for 3 years, has been a smooth and consistent experience the entire time. Quantconnect makes building a trading algorithm highly accessible to anyone with an idea and a bit of coding knowledge. Handling all the background infrastructure for you, they make it easy to build your algorithm, backtest against market data, and even deploy it live with a supported brokerage. Sometimes it can be a bit difficult to learn the syntax and what a method does, but there is a lot of documentation available, as well as community forums. All this has really helped me focus on my strategy rather than building infrastructure from the ground up and I would definitely recommend them to anyone looking to try out quant finance or algorithmic trading.

I wasn’t a programmer I wasn’t a programmer, took a python basics course on youtube and their free bootcamp course and I was surprised how quickly I picked up object oriented programming and algorithmic trading coding on their platform. The stocks data is free up to seconds timeframe, after a long research on competitors I choose quantconnect and it was up to my expectations.

Can only say good things! Over two (fun!) years the QuantConnect team have assisted me in (1) My programming...which at the beginning was all but non-existent. With this, the customer support, community help and other resources e.g. GitHub provided me with the required information to develop my algos. (2) Connectivity....I can connect one of my algos to one of my Interactive Brokers accounts in about 2 minutes. Its that easy. (3) Ability to license....Many of the systems I have developed over the last couple of years and submitted to the AlphaStreams marketplace are being licensed. Like any other endeavor in life - this takes hard work and a lot of effort. I have had no problems with backtest times - but obviously the times will depend on the amount of data being crunched in the background. So Im very happy - a friendly bunch of people doing real innovative stuff. I cant wait what the next few years bring!

Making Quant Analysis and Trading accessible to everyone I knew about QuantConnect when I was desperately searching online for Options Historical data in the US markets. Everything else I found was expensive and required me a lot of manual handling. Not to say they weren't realistic at all (i.e. didn't consider company splits, adquisitions, etc.). QuantConnect and the open source lean framework made it very easy to implement trading algorithms (with a results very close to what I get in Interactive Brokers; including fees, splits, dividends, option assignments, etc.) at a very cheap cost (you just pay for the cloud computing resources). Being open source makes it very easy to figure out how to do things, however, they have interactive tutorials that will prepare anyone with basic development skills to implement real-live trading algorithms. Not to say the community is awesome and very helpful. QuantConnect is easily escalable for both small individuals and large corportations. Many organizations and hedge funds use it for their analysis and live trading.

Alex stayed the course and helped me… Alex stayed the course and helped me with an issue that turned out to be not QuantConnect’s fault. But it turns out his idea led to a resolution. Much appreciation!!!
