+## Monthly Dashboard
+
+The dashboard displays:

+- **Winning Trades**: Number of profitable trades  
+- **Win Rate**: Percentage of winning trades
+- **Trading P/L**: Profit/loss from trades
+- **Dividend Income**: Total dividends received
+- **Total Return**: Combined trading P/L and dividends

+## Trade Details

+
+- **Symbol**: Stock ticker
+- **Buy Date**: Purchase date
+- **Sell Date**: Sale date
+- **Buy Price**: Purchase price per share
+- **Sell Price**: Sale price per share
+- **Volume**: Number of shares traded
+- **Profit/Loss**: Total profit or loss

+## Hybrid Matching Algorithm
+
+The system uses a hybrid matching algorithm that combines:
+
+1. **Broker Realized Gains/Losses** - Pre-calculated lot matches with definitive P/L
+2. **Transaction History** - Complete record of all buy/sell transactions
+
+This achieves **broker-level accuracy** for closed positions.
