  "trend_summary": "DOGE has shown mixed signals over the past 15 days, with periods of heightened volatility. Key support levels are holding at $0.06, while resistance has been forming around $0.065. Short-term moving averages (e.g., 7-day) indicate a slight upward trend, but RSI readings hover near 55, suggesting the asset is neither overbought nor oversold. Volume has been inconsistent, further reflecting uncertainty in the market.",
  "buy_signal": true,
  "sell_signal": false,
  "hold_signal": false,
  "sentiment_score": 0.23
}
```

### Explanation of the Output:
1. **Trend Summary**:
   - The summary reflects DOGE's recent performance based on the past 15 days.
   - It highlights key technical indicators such as support and resistance levels, moving averages, RSI values, and trading volume.
   - The data suggests a mildly positive market trend with uncertain momentum.

2. **Buy Signal**:
   - A buy signal is recommended due to the slight upward trend and stable support levels. However, the recommendation considers a moderate risk tolerance (0.6), as DOGE could benefit from a localized bullish breakout.

3. **Sell Signal**:
   - A sell signal is not recommended as the indicators do not show immediate bearish pressure.

4. **Hold Signal**:
   - A hold signal is also not suggested because the current setup favors a speculative buy rather than a passive holding strategy.

5. **Sentiment Score**:
   - The sentiment score of 0.23 (on a scale from -1.0 to 1.0) reflects mild bullishness in the market. Positive but low sentiment signifies there is interest in DOGE, albeit without strong enthusiasm.
