What’s this Reducible Errors thing?

Hi, I’m Agustin Lebron. I’m:

• a former trader and researcher at Jane Street Capital,

• the author of a semi-obscure but well-reviewed book on trading,

• and a blissfully minor #FinTwit personality.

I started Reducible Errors to give people an honest look at what real quant trading and math learning looks like. Unedited and raw.

Why subscribe?

Finding an edge in financial markets isn’t easy. To prove it, every week I drop an over-the-shoulder video of me doing what I do. Researching trading ideas. Building strategies. Probably learning some math along the way.

It’s not the sanitized version you see in books and articles and how-to videos. It’s messy and confusing, and sometimes it’s pretty frustrating. And for $10 a month, you get a front-row seat.

All the mistakes and blind alleys, and the occasional successes. As honest and raw as I can make it. You’ll get summaries and commentary too: what I thought was good, what I’d do differently next time, and also ideas for you to explore.

Who’s our audience?

• People who want to learn about trading, about math, and about extracting signal from noise.

• People who are tired of listening to supposed experts who claim to have “the secret” to making money in trading. Or anywhere else.

• People who are at least as interested in the process as in the results.

• So far our subscribers include students, prop traders, enthusiastic amateurs, and more than a few hedge fund managers.
