Dear Quants,

Happy Thanksgiving! It has been an intense but rewarding year, and we’re incredibly grateful to continue serving the community. Thanks to your continuous feedback, patience, and support, the QuantConnect platform is the world's leading platform for researching, backtesting, and live trading quantitative strategies. This year, we made significant progress in AI, speed, and implemented hundreds of minor fixes to enhance LEAN. 

We’re most excited about Mia V2, a fully agentic AI deeply integrated with the cloud IDE. She is a 10x productivity unlock and your own personal quant developer. Mia can pair program, fix code bugs, or even implement full strategies. Soon, we’ll deploy a suite of agents to assist you in every aspect of your quant trading. Key advances this year include:

  • Mia V2, Agentic Quant AI 🤯- Automates your quant coding (now in public beta).
  • Published “Hands-on AI Trading” Book.
  • 250% Speed Increase in LEAN Kernel (coming soon).
  • 400% Increase in Live Volumes, ≈$65B monthly volume.
  • Deployment of Charles Schwab, tastytrade, and TradeStation brokerages.
  • Shipped 350 other bugs and feature updates.

We’ve kept prices steady in the face of inflation for three years now, an effective discount of 10%, while continuously improving the platform.

There has never been a better time to build on QuantConnect. We are offering holiday weekend discounts on annual plans and datasets using the discount code "black-friday-2025."

30% Extra Tokens to Power AI Coding:

Meet Mia V2, your incredibly talented AI quant developer. With minimal effort and a few AI tokens, she can write your entire strategy. In testing we were able to have Mia V2 write 5-6 variants of a strategy, debug them, run the backtests, and optimize the performance, all for a $2-4 chat session. For this week, you’ll receive an extra 30% tokens for purchases of more than $100 QCC. 

30% Off Annual Seat Plans: 

Upgrade your core organization type to take advantage of team collaboration, higher cloud log limits, and coding on-premise with our local VSCode extension. Institutional plans include AES256 encryption of project source code.

30% Off Annual Large Nodes: 

Larger B8-16, R8-16, L1-2, and L2-4 compute node types are now 30% less on annual plans. Deploy your strategies on our battle-tested live trading infrastructure.

20% Off Universe and Security Master Datasets:

Discounts on datasets to setup LEAN locally, covering Universe and Security Master datasets. Avoid common quant mistakes, such as selection and look-ahead bias, using our comprehensive US Equities market corporate actions data from 1998 to the present. This data covers splits, dividends, mergers, IPOs, delistings, and updates for the next year.

Let us power your algorithmic trading infrastructure in 2026. Set yourself up for success by harnessing the best technology possible, and support our radically open quant mission.

Sincerely,

Team @ QuantConnect
