Data note: trades are pulled from IBKR's execution feed (symbol, side, price, size, realized P&L). Strike / expiry / call-vs-put detail isn't available from that feed, so the log shows leg count and premium instead of exact strikes. Win rate, P&L, and expectancy are computed straight from IBKR's own realized_pnl field, not re-derived, so they can't drift the way TradesViz did.
