     - This change aims to improve net profitability by ensuring that rebalancing fees are only paid when the delta imbalance is statistically significant.
 - **Logging Improvements**:
     - Updated `[IDLE]` log format to show estimated **BUY (B)** and **SELL (S)** trigger price levels instead of raw delta difference. This provides better visual feedback on how far the price is from the next rebalance.
+- **Fishing Order Logic**:
+    - Implemented a "Fishing Order" mechanism that keeps a Maker order (10% of hedge size) resting at the `entry_price` while in the safe zone.
+    - **Logic Update:** Configured to always place a **Limit BUY** at the entry price (when Px > Entry) to reduce the hedge size at break-even.
+    - **Fix:** Updated position tracking to use the actual Hedge Entry Price from Hyperliquid instead of the LP Strategy entry price.
+    - Integrated fishing order tracking to distinguish it from standard rebalance orders.
