Products
StatOasis sells four things on this site: Overfit, a free twice-monthly research newsletter; the StatOasis Community, free to join; 36 Mean Reversion Entries, a $37 book with open code; and the Algo Trading Masterclass, a $3,499 course covering the whole systematic trading workflow. Two are free. Every one of them is built on the same published research.
Four products, in the order a newcomer should meet them. The free two are not lesser versions of the paid two - they are how you find out whether this way of working suits you before spending anything.
| Product | What it is | Price | Best for |
|---|---|---|---|
| Overfit - the newsletter | Newsletter | Free | Anyone deciding whether this way of working is for them. |
| The StatOasis Community | Community | Free to join | Traders who learn faster with other people in the room. |
| 36 Mean Reversion Entries | Book + code | $37 | Someone who already trades and wants a bigger set of entries to test. |
| Algo Trading Masterclass | Course | $3,499 | Traders who want a process they own rather than signals to follow. |
Newsletter
One backtested idea, twice a month, with the numbers attached.
The research desk's notebook rather than a market-commentary blast: each issue takes one idea, tests it, and publishes what came back - including the results that killed the idea. Free, and the front door to everything else here.
Community
Where the research gets argued about, with the tools thrown in.
Traders, investors, programmers and tinkerers sharing strategies, code and feedback - plus live Q&A webinars, a searchable answer database, and nine members-only bonuses including StrategyQuant X plugins and indicators. It runs on its own platform at community.statoasis.com.
Book + code
Forty dip-buying entries, tested the same way and ranked on the results.
Thirty-six core mean-reversion entries plus four you will not find published elsewhere - 40 signals across 8 categories, each stated as a codeable rule and backtested on 30 years of SPY data. Open EasyLanguage and PowerLanguage code for every entry.
Course
The whole build-and-validate process, taught end to end, without code.
Five modules and 94 lessons covering the full workflow: finding an edge, building it without writing code, testing whether it survives, automating the search, and running the result as a live portfolio. Taught in StrategyQuant X, with a one-to-one session with Ali included.
With whichever of the free two suits how you learn. Nothing here needs to be bought to be useful, and the research library and the methodology every study is run to are free to read with no signup at all - including the studies that failed.
Read a few issues and lurk in the community. Both are free, and between them they show you exactly how the work gets done before you commit to anything.
The book is the cheapest way to widen the set of entries you test. Forty of them, each stated as a rule you can code, with the results shown either way.
The Masterclass is the only one that teaches the end-to-end workflow - finding an edge, testing it honestly, and running it live. It is also the only one that costs real money.
Four things on statoasis.com: Overfit, a free twice-monthly research newsletter; the StatOasis Community, free to join; 36 Mean Reversion Entries, a $37 book with open code; and the Algo Trading Masterclass, a $3,499 course that teaches the whole systematic trading workflow. StatOasis also makes AlgoChef, a strategy-validation tool that lives at algochef.app.
Yes - two of the four. The Overfit newsletter is free, and the StatOasis Community is free to join today, including its live Q&A webinars, its answer database and its member bonuses. The whole research library and the methodology every study is run to are free to read with no signup at all.
$3,499, paid once - or $2,999 for waitlist members, who receive a private coupon when an enrolment window opens. There is no subscription and the fee does not renew. Enrolment opens four times a year and each window stays open for six days.
With the newsletter and the community, both free. They are not lesser versions of the paid products - they are how you find out whether this way of working suits you before spending anything. The book is the next step if you already trade and want more entries to test; the Masterclass is for building the whole process.
No. The Algo Trading Masterclass is taught end to end without writing code, in StrategyQuant X. The book ships working EasyLanguage and PowerLanguage code you can use as-is, and states every entry as a plain rule so it can be ported to any other platform by hand.
