Long time believer, first time promoter. I've been using Quantconnect for about two years but they've just released new capabilities for options research, based on user feedback, that prompted me to add a review. They listen to, care about, and build new features for their users (free features). Highly recommend.

Recommended I have been programming on my bot for over 2 years. In the beginning it was difficult to get to know the platform because there is a lot of possibilities coming at you. But once you understand how this platform works and were to find the information. It's a pleasure to work on your bot. Pros: - Strong community that mostly answers your questions in 24h or max 48 hours. - Working locally or on the platform - Possibility of coding 100% your own strategy - Live Trading with a lot of markets (Equity, Crypto, Forex, Futures). - They listen to proposals to improve the platform and take immediate action. - If using the bronze membership your getting professional help within an hour. (It's normal they charge an amount for the professional help, nothing is free these days.) - Implementing email, sms, telegram messages, ... of the orders the bot is making. Cons: - If u have zero experience programming in Python or C# it's hard to program your own bot despite their learning center. - Maybe an app on the cellphone would be nice. So you can check your bot/code anytime you want (not would be something extra). A tip: Keep persevere once your bot is trading live it's a reward for all the hard work.

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,

Accelerator of analysis! Really nice platform to boost your algorithmic trading.

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!
