## Why
|
|
|
|
TA-Lib pattern recognition and ML model training/inference capabilities are fully implemented in the Python backend but require terminal commands to use. Users cannot select TA-Lib patterns, trigger training, or switch between trained models from the UI — making these powerful features inaccessible during normal annotation workflow.
|
|
|
|
## What Changes
|
|
|
|
- Add a **TA-Lib pattern panel** in the sidebar where users can select from the 50 implemented CDL pattern functions, run them on the current chart, and see results as span annotations
|
|
- Add ability to **bulk delete** TA-Lib-generated annotations (by source) or selectively keep them for ML training
|
|
- Add a **training panel** where users can select a model type (RandomForest, XGBoost), configure basic parameters, and trigger training from the UI
|
|
- Add a **model selector** to the existing prediction panel so users can switch between trained models and apply them to the current chart
|
|
- Add new API endpoints to support TA-Lib pattern detection and training triggers from the frontend
|
|
- Expose training run history and status in the UI
|
|
|
|
## Capabilities
|
|
|
|
### New Capabilities
|
|
- `talib-pattern-ui`: UI panel for selecting and running TA-Lib CDL pattern recognition functions on the current chart, viewing results as span annotations, and managing (keeping/deleting) detected patterns
|
|
- `training-ui`: UI panel for selecting model type, configuring parameters, triggering training runs, and viewing training history/status
|
|
- `model-selector`: UI for listing available trained models, switching the active model, and applying predictions to the current chart
|
|
|
|
### Modified Capabilities
|
|
- `prediction-ui`: Add model selection dropdown to existing prediction panel, integrate with model-selector for switching active model
|
|
- `backend-api`: New endpoints for TA-Lib pattern detection, training triggers, model listing, and training status
|
|
|
|
## Impact
|
|
|
|
- **Frontend**: New sidebar panels (TA-Lib patterns, training), modifications to PredictionPanel component
|
|
- **Backend API (Next.js)**: New proxy routes for TA-Lib and training endpoints
|
|
- **ML Service (FastAPI)**: New endpoints for pattern detection, training trigger, model listing
|
|
- **Database**: May need training_runs table exposure via API (already exists in PostgreSQL)
|
|
- **Dependencies**: No new dependencies — all TA-Lib and ML libraries already installed
