+#### priority_fee Parameter
+
+The `priority_fee` parameter is an optional `PriorityFee` that allows you to override the default priority fee settings for individual transactions:

+- **Purpose**: Provides fine-grained control over transaction priority fees on a per-transaction basis
+- **Usage**:
+  - Can be passed to `buy()` and `sell()` methods to override the global priority fee settings
+  - If not provided, defaults to `None` and uses the priority fee settings from `TradeConfig`
+  - When provided, the `buy_tip_fees` array will be automatically padded to match the number of SWQOS clients
+- **Benefits**:
+  - Allows dynamic adjustment of priority fees based on market conditions
+  - Enables different fee strategies for different types of transactions
+  - Provides flexibility for high-frequency trading scenarios
