You journal options trades by recording the underlying symbol, strike price, expiration date, option type (call or put), entry and exit prices, contract count, and the strategy used. The first step is to decide what type of information to track, including the underlying asset, expiration date, strike price, option type, entry and exit prices, profit/loss, and any other pertinent information.
Track each leg of multi-leg trades separately, then group them under the parent strategy (vertical, iron condor, butterfly) so reports show real spread-level P&L. Layer in the Greeks (delta, theta, gamma, vega) and implied volatility at entry, plus your reasoning and emotional state for each trade.
