He then talks about the biggest risk that faces market makers:

Adverse selection.

It's great since most people think of risk as standard (deviation.) Image

OpenBB dropped the $0 cost financial AI agent workstation.

You can get 405 free data sources (and an AI Copilot).

Here's what you missed (in 90-seconds): OpenBB Terminal Pro
In case you're unfamiliar:

OpenBB is the first AI financial workstation that combines data with an AI agent to transform investment research.

• Private (your data is not shared)
• 100s of free data sources
• Custom data backends
• Advanced AI Copilot

How it works:
Set up a custom, local data server with 370 sources of free market data.

No coding required (just double click an icon):

My master's degree completely failed to teach me how to test trading strategies.

So I spent 40 hours looking for Python backtesting libraries.

Then I started using the best ones.

But unlike my quant finance degree, these won't cost you $90,000.

Here they are for free. Poof

Jupyter Notebook is the most powerful tool for Python.

But most people don’t know the hidden features.

Need a quick web app?

Or create REST APIs?

Here are the 6 ways to use Jupyter Notebook you never knew existed: The notebook to rule them all.
Jupyter Notebook is a web app for creating and sharing computational documents.

When I say powerful, here's what I mean:

• It supports 40 languages
• Produces rich, interactive output
• Leverages big data tools like Spark

So, what else can we do with Jupyter Notebook?
Package Development

nbdev let's you develop and publish Python packages right from Jupyter Notebook.

It generates documentation and publishes on GitHub Pages. You can also write tests and setup CI with GitHub Actions.
