# Generating Trading Signals

## Overview

Multi-indicator signal generation system that analyzes price action using 7 technical indicators and produces composite BUY/SELL signals with confidence scores and risk management levels.

**Indicators Used:**
- RSI (Relative Strength Index) - Overbought/oversold
- MACD (Moving Average Convergence Divergence) - Trend and momentum
- Bollinger Bands - Mean reversion and volatility
- Trend (SMA 20/50/200 crossovers) - Trend direction
- Volume - Confirmation of moves
- Stochastic Oscillator - Short-term momentum
- ADX (Average Directional Index) - Trend strength

## Prerequisites

Install required dependencies:

```bash
pip install yfinance pandas numpy
```

Optional for visualization:
```bash
pip install matplotlib
```

## Instructions

### Step 1: Quick Signal Scan

Scan multiple assets for trading opportunities:

```bash
python {baseDir}/scripts/scanner.py --watchlist crypto_top10 --period 6m
```

Output shows signal type (STRONG_BUY/BUY/NEUTRAL/SELL/STRONG_SELL) and confidence for each asset.

### Step 2: Detailed Signal Analysis

Get full indicator breakdown for a specific symbol:

```bash
python {baseDir}/scripts/scanner.py --symbols BTC-USD --detail
```

Shows each indicator's contribution:
- Individual signal (BUY/SELL/NEUTRAL)
- Indicator value
- Reasoning (e.g., "RSI oversold at 28.5")

### Step 3: Filter and Rank Signals

Find the best opportunities:

```bash
# Only buy signals with 70%+ confidence
python {baseDir}/scripts/scanner.py --filter buy --min-confidence 70 --rank confidence

# Rank by most bullish
python {baseDir}/scripts/scanner.py --rank bullish

# Save results to JSON
python {baseDir}/scripts/scanner.py --output signals.json
```

### Step 4: Use Custom Watchlists

Available predefined watchlists:

```bash
python {baseDir}/scripts/scanner.py --list-watchlists
python {baseDir}/scripts/scanner.py --watchlist crypto_defi
```

Watchlists: `crypto_top10`, `crypto_defi`, `crypto_layer2`, `stocks_tech`, `etfs_major`

    Trend            | BUY          | Uptrend: price above key MAs
    Volume           | STRONG_BUY   | High volume (2.3x) on up move
    Stochastic       | STRONG_BUY   | Oversold (%K=18.2, %D=21.5)
    ADX              | BUY          | Strong uptrend (ADX=32.1)
----------------------------------------------------------------------
```

### Signal Types

| Signal | Score | Meaning |
|--------|-------|---------|
| STRONG_BUY | +2 | Multiple strong buy signals aligned |
| BUY | +1 | Moderate buy signals |
| NEUTRAL | 0 | No clear direction |
| SELL | -1 | Moderate sell signals |
| STRONG_SELL | -2 | Multiple strong sell signals aligned |

### Confidence Interpretation

| Confidence | Interpretation |
|------------|----------------|
| 70-100% | High conviction, strong signal |
| 50-70% | Moderate conviction |
| 30-50% | Weak signal, mixed indicators |
| 0-30% | No clear direction, avoid trading |

## Configuration

Edit `{baseDir}/config/settings.yaml`:

```yaml
indicators:
  rsi:
    period: 14
    overbought: 70
    oversold: 30

signals:
  weights:
    rsi: 1.0
    macd: 1.0
    bollinger: 1.0
    trend: 1.0
    volume: 0.5
```

## Error Handling

See `{baseDir}/references/errors.md` for common issues:
- API rate limits
- Insufficient data handling
- Network errors

## Examples

See `{baseDir}/references/examples.md` for detailed examples:
- Multi-timeframe analysis
- Custom indicator parameters
- Combining with backtester
- Automated scanning schedules

## Integration with Backtester

Test signals historically:

```bash
# Generate signal
python {baseDir}/scripts/scanner.py --symbols BTC-USD --detail

# Backtest the strategy that generated the signal
python {baseDir}/../trading-strategy-backtester/skills/backtesting-trading-strategies/scripts/backtest.py \
  --strategy rsi_reversal --symbol BTC-USD --period 1y
```
