TradingView Screener

## Setup (Run Once)

Before first use, run the install script to create a venv and install dependencies:
```bash
bash skills/tradingview-screener/install.sh
```
This creates `.venv/` inside the skill directory with all required packages.

## Execution

All scripts use the skill's own venv:
```bash
skills/tradingview-screener/.venv/bin/python3 skills/tradingview-screener/scripts/<script>.py [args]
```

**Windows:**
```bash
skills/tradingview-screener/.venv/Scripts/python.exe skills/tradingview-screener/scripts/<script>.py [args]
```

## Modes

| Mode | Description | Script |
|------|-------------|--------|
| **Screen** | One-time scan with filters, columns, sort | `screen.py` |
| **Signal** | YAML-driven signal detection (pre-filters + computed signals) | `signal-engine.py` |

## Quick Start

### Screen Mode
```bash
skills/tradingview-screener/.venv/bin/python3 skills/tradingview-screener/scripts/screen.py \
  --asset-class stock --limit 20 \
  --filters '[{"field":"MARKET_CAPITALIZATION","op":">","value":1000000000}]' \
  --columns NAME,PRICE,CHANGE_PERCENT,VOLUME \
  --sort-by VOLUME --sort-order desc
```

### Signal Mode
```bash
# List available signals
skills/tradingview-screener/.venv/bin/python3 skills/tradingview-screener/scripts/signal-engine.py --list

# Run a signal
skills/tradingview-screener/.venv/bin/python3 skills/tradingview-screener/scripts/signal-engine.py --signal golden-cross
```
