Tradability Ranking for Pair Ideas
Create software that ranks candidate pairs not only by statistical fit but by practical tradability, combining model confidence, spread behavior, liquidity, cost sensitivity, and live execution risk. This turns a large candidate universe into a prioritized list more aligned with deployable opportunities.
Why this matters
You may scan thousands of assets and still end up with only a handful of pairs worth considering. That is not just a filtering problem; it is a decision problem where statistical validity, parameter stability, liquidity, and cost resilience all matter at once. Basic cointegration or OU screens produce candidates, but they do not tell you which names are likely to survive contact with live execution. As a result, you spend time investigating setups that look elegant in research but are poor trading vehicles. A ranking system that combines research diagnostics with tradability signals would help you focus on opportunities that are not only statistically interesting but realistically deployable.

MVP Scope · 1–2 weeks
- Design an input format for candidate pair metrics and metadata
- Build a baseline scoring model using liquidity, spread, volatility, and parameter-confidence features
- Create a ranked output page with sortable explainability columns
- Add manual labels such as tradable, fragile, and discard for user feedback
- Prepare a sample dataset and scoring walkthrough for common ETF pairs
- Train a first learning-to-rank model from synthetic and user-labeled examples
- Add feature importance and confidence bands for each ranked pair
- Implement custom weighting profiles for stability-first or return-first users
- Add export back into Python notebooks and CSV formats
- Run a beta with users comparing ranked lists against their existing filtering process
Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1Without enough outcome data, the ranking model may not outperform expert-crafted rules, making it hard to justify payment.
- 2The market may view ranking as a feature inside existing research stacks rather than a standalone product.
- 3Users may resist sharing enough candidate data to improve the model, slowing quality improvements.
Evidence Summary
How AI synthesized this insight — no verbatim quotes
A couple of comments pointed out that low conversion from a large universe may be normal and that better prioritization matters more than forcing more pairs. There was also explicit interest in using a learning-based ranking approach to down-rank unstable or weak candidates. This supports a product focused on tradability scoring rather than pure idea generation.
