 - **cache_latest_only** (bool): Whether to cache only the latest events.
-- **arb_mode** (str): Specifies the arbitrage mode. Options include:
-    - **single**: Arbitrage between one Carbon curve and one other exchange curve.
-    - **multi** (default): Arbitrage between multiple Carbon curves and one other exchange curve.
-    - **triangle**: Triangular arbitrage between one Carbon curve and two other exchange curves.
-    - **multi_triangle**: Triangular arbitrage between multiple Carbon curves and two other exchange curves.
-    - **bancor_v3**: Arbitrage between two Bancor v3 pools and one other exchange curve.
+- **arb_mode** (str): Specifies the arbitrage mode. 
+  - **Types of arbitrage**: 
+    - **Pairwise**: This includes arbitrage trades between two liquidity pools that contain the same tokens. For example: USDC > LINK, LINK > USDC
+    - **Triangular**: This includes arbitrage trades between three liquidity pools that can create a triangular route, starting and ending in the same token. For example, USDC > ETH, ETH > LINK, LINK > USDC
+    - **Multi**: These modes can trade through multiple Carbon orders as a single trade.
+  - **arb_mode options**:

 - **polling_interval** (int): Bot's polling interval for new events.
