🎯 TRADING DECISION INSTRUCTIONS (SPOT ONLY - LLM MUST ANALYZE PATTERNS AND DEFINE EXIT STRATEGY):

1.  **PERFORM CHART PATTERN ANALYSIS:** Based *ONLY* on the provided 'RAW CANDLE DATA SUMMARY & STATISTICS' section above, identify relevant chart patterns (Triangles, Flags, Head & Shoulders, etc.) and candlestick patterns (Engulfing, Doji, etc.).
2.  **INTEGRATE ALL DATA:** Combine YOUR pattern analysis with technicals, strategy analysis, whale activity, market context, news, and the 'LEARNING ENGINE FEEDBACK'.
3.  **ADHERE STRICTLY TO SPOT TRADING RULES:** Only decide 'BUY' (LONG) or 'HOLD'. DO NOT suggest 'SELL'.
4.  **DEFINE EXIT STRATEGY (CRITICAL):** If (and only if) action is 'BUY', you MUST define the dynamic exit strategy (Exit Profile) and its parameters. This profile will be executed by a separate tactical bot.
    -   `"exit_profile"`: Choose one: "ATR_TRAILING" (Recommended for trends/breakouts), "FIXED_TARGET" (Recommended for mean reversion/scalping), "TIME_BASED" (Exit after X minutes regardless), "SIGNAL_BASED" (Emergency exit on opposite signal - *Use with caution*).
    -   `"exit_parameters"`: Define parameters for the chosen profile.
        -   For "ATR_TRAILING": {{"atr_multiplier": 2.0, "atr_period": 14, "break_even_trigger_percent": 1.5}} (break_even_trigger_percent moves stop to entry when profit hits 1.5%)
        -   For "FIXED_TARGET": {{"time_stop_minutes": 120}} (Hard stop if target not hit in 120 mins)
        -   For "TIME_BASED": {{"exit_after_minutes": 60}}
        -   For "SIGNAL_BASED": {{"emergency_volume_spike_multiplier": 5.0}} (Exit if reverse volume spike > 5x average)
5.  **DEFINE HARD STOPS:** You must still provide the initial "hard" stop_loss (catastrophic failure stop) and the final "take_profit" target. The dynamic exit profile operates *within* these boundaries.

🎯 RE-ANALYSIS INSTRUCTIONS (SPOT - LONG POSITION):

1.  **ANALYZE UPDATED DATA:** Evaluate if the original LONG thesis still holds based on the updated raw candle data summary, technicals, patterns (provided above), whale activity, market context, and learning feedback.
2.  **VALIDATE PATTERNS:** Consider the 'UPDATED PATTERN ANALYSIS RESULTS' provided. Does the recent price action confirm or invalidate these patterns?
3.  **DECIDE ACTION (HOLD/CLOSE/UPDATE):** Based on the comprehensive analysis, decide whether to HOLD, CLOSE_TRADE (exit the LONG position), or UPDATE_TRADE (adjust SL/TP and/or the Exit Profile for the LONG position).
4.  **IF UPDATING (CRITICAL):** If action is UPDATE_TRADE, you MUST provide:
    -   `new_stop_loss` (New hard stop)
    -   `new_take_profit` (New final target)
    -   `new_exit_profile`: (e.g., "ATR_TRAILING") - Can be the same or different.
    -   `new_exit_parameters`: (e.g., {{"atr_multiplier": 1.5}}) - Must match the new profile.
5.  **PROVIDE DETAILS:** Justify your decision clearly, integrating all data points.

CRITICAL: The decision must be one of HOLD, CLOSE_TRADE, or UPDATE_TRADE for the existing LONG position.
