Contributors
Your model, scored on what the market does.
Why contribute
Research that turns into a track record.
Ranked on results.
Your standing follows your models' scores. Seniority and job titles don't come into it.
Real market outcomes.
Every submission is scored against realised NSE returns, round after round.
Weight in the book.
Models with a strong record carry more weight in the meta-model the fund trades.
Who can join
We look at the work, not the CV.
If you can model data, or want to learn how, you can take part. You don't need a finance background.
- Data scientists exploring financial markets
- Machine learning engineers curious about live systems
- Quantitative researchers from any background
- Software engineers who like pulling signal out of noisy data
- Statisticians, mathematicians, physicists
- Self-taught practitioners with real projects to show
How it works
Six steps, repeated every round.
Each round opens at 19:00 IST the evening before an NSE trading session and closes at 09:00 IST on the session day. Over weekends and holidays it stays open until 09:00 IST on the next session.
- 01
Discover
Read the rules and download the round's dataset.
- 02
Build
Engineer features, train, iterate. Any method is fine.
- 03
Submit
Send one prediction per name before 09:00 IST.
- 04
Improve
Scores arrive once the 20-session outcome is known.
- 05
Contribute
Strong models carry more weight in the meta-model.
- 06
Grow
Your record builds under a public handle.
Skills that help
What tends to matter.
None of these are requirements. Plenty of contributors start without several of them and pick them up along the way.
Machine learning
Supervised, unsupervised or deep. Use whatever works.
Python
What most contributors use: NumPy, pandas, scikit-learn, PyTorch.
Feature engineering
Turning raw features into something a model can learn from.
Statistics
Knowing when a good result is only noise.
Curiosity
It keeps you testing new ideas after the first one fades.
Discipline
A steady model outscores an erratic one over enough rounds.
Common questions
A few things worth knowing.
No. A background in ML, physics, engineering or research is as useful as one in finance, and the market side can be learned as you go.
Bring your models. Meet the market.
