I've been using it for around 6 months I've been using it for around 6 months. My bot is not ready yet, but it's still my best choice for these privileges: 1. connection with the interactive brokers 2. easy to use Python 3. Real market data is available 4. many built-in Python libraries. I will add here that I started a very nub in coding, and it is not easy to begin there, I mean things like data collection, especially for futures (I still haven't tried Options so far). With the help of CHatGPT which also knows the QuantConnect environment, it is now possible to code my own professional strategy for trading,

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.

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.

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.

This is the best platform for… This is the best platform for individuals. I seldom subscribe to 'pro-account' things, but I did for this one. The dirty stuff like data cleansing, backtesting framework, error handling is done by them and I can focus on the fun stuff, printing money.
