Capital markets
Market Screening Terminal
Situation
A research operator needed custom scoring over market data without shipping sensitive series to a vendor cloud.
What mattered
- Must work offline-first; cloud is optional, not required
- Charts stay responsive with dense series
- Scoring logic can change without rebuilding the whole tool
- Installs on a single workstation
Problem
Off-the-shelf screeners cannot run custom machine-learning classifiers on local market data.
Approach
We built a local screening tool for crypto and Brazilian equities, with interactive charts and no requirement to send data to a vendor cloud.
What we delivered
A desktop-friendly terminal the operator runs locally: load series, apply their classifiers, and explore results on charts without a mandatory remote backend.
Outcome
Custom screeners run fully on the operator’s machine. Data stays local.
