QuantConnect

The team at @QuantConnect recently created an integration that brings Databento's real-time and historical market data directly into LEAN, their open-source algorithmic trading engine. For the hundreds of thousands of developers already building with LEAN, adding a Databento API key provides our normalized market data across research, backtesting, and live trading - all within their existing setup. ⬇️ To get started, check out the guide below

Final count down to the Quaint Quant Conference in Dallas this Friday! Our founder @JaredBroad is speaking on Applied AI for Quant Finance ✨ - come say hello! quaintquantconference.com/agenda/

@Netflix just raised prices again. Second time in 14 months. 📺 Netflix Standard: $15.49 → $19.99 (+29%) 🖥️ QuantConnect Researcher Pack: $60 → $60 (+0%) 📈 US Inflation: +16.3% 💾 Server RAM: +172% We run colocated backtesting servers and host 400TB+ of financial data. Our costs exploded. We didn't raise prices once in 4+ years. In real terms, our users pay ~16% less today than in January 2022.

Classical ML + Deep Learning CNNs + Amazon Chronos Foundation Models + @QuantConnect = Can AI actually generate alpha? 📈🤖 Huge thanks to the 50+ of you who packed the room at the PyHou Meetup! Your energy was unreal. 🙏 As promised, I’ve refined the entire presentation into a massive open-source masterclass. Here is the complete teardown 👇 (1/4)

Thanks @donfogliani, we prefer being underrated 😁💪. Limits will keep improving but we'd estimate about 1,000 strategy-lines today which should cover 99% of users on QC as each line is very powerful. e.g. Simply "self.add_universe(self._fundamental_function)" does 50K-lines of work under the hood. We have a roadmap item for multi-strats but its not ready yet. We're scaling up internal agent tooling now to build faster and I hope we'll be able to get to more of these long tail, hard features faster.

Mia V2 is perhaps the most underrated AI finance tool in the market. Question from a user perspective: what's the practical ceiling on strategy complexity? At what point does the agentic loop break — how many backtesting iterations can Mia run before losing coherence on the original design intent? And is there a roadmap for multi-strategy portfolio construction (e.g., 5 concurrent strategies with cross-strategy risk management)?

Happy Thanksgiving Quants! We're grateful for you! This week there is 20-30% off plans, Agentic Quant AI Tokens, and some data on QuantConnect. Check it out in comment below. We've quietly released Mia V2 to public beta. Its pretty mind blowing 🤯🎉, full agentic quant LLM.

@StoicInvestor42 We'll keep driving our MCP and LLM tech use in QC. We named it Mia for the coud version... something special there coming soon!

Although @QuantConnect did recently implement an MCP server. So maybe the easiest starting point is to simply connect to it using ChatGPT.

I found this book - "Hands-On AI Trading with Python, QuantConnect, and AWS" - but its AI seems to refer primarily to Machine Learning. Any books or references about connecting GenAI/LLMs to QuantConnect APIs? Seems like it would be an interesting experiment.

vBase now lets you time stamp your portfolio state to block chain for an auditable track record of your strategy.

@anthonywlicausi @alpaca @Tesla @elonmusk We love hearing these success stories 🙌🙌

The model I built on @QuantConnect and refined over almost 6 months finally went live last week on @Alpaca and bought @Tesla at $336 the day before the news came out about @elonmusk’s proposed trillion dollar pay package…. Up 17% in less than a week and counting! This strategy did 9,100% in a 5 year back test with a Sharpe Ratio of 1.87 and max drawdown of 20% earning us the ranking of the #1 Quant Model in the World for 2025 by Fund Rank Global.
