## Direct answer

An options journal is an evidence trail that connects what was knowable at decision time with the position actually traded and the account result. Final profit alone cannot distinguish a sound process with an adverse outcome from an unsupported decision that happened to profit. The journal should preserve contemporaneous facts before memory and hindsight rewrite the thesis.

## A complete journal schema

Use one stable trade or thesis ID and append events rather than overwriting history.

| Block | Minimum fields |
| --- | --- |
| Contract | full option symbol, underlying, Call/Put, side, open/close, quantity, strike, expiration, multiplier, deliverable, exercise and settlement style |
| Thesis | direction, magnitude, deadline, catalyst, evidence, invalidation, alternative structures, and reason not to wait |
| Market snapshot | timestamp and timezone, underlying quote, every leg's Bid/Ask and size, package quote, volume, open interest, IV term/skew, Greeks with model source |
| Risk | theoretical maximum, joint stress loss, assignment cash, margin/buying-power change, concentration, planned exit and expiration handling |
| Execution | order type, limit, submission and fill times, partial fills, route if known, fill price, commissions, fees, and price benchmark |
| Lifecycle | thesis updates, dividends, earnings, corporate actions, halts, margin changes, rolls, exercise, assignment, transfers, and cash movements |
| Close and review | closing reason, executable quote, realized cash ledger, fees, tax-lot reference, rule adherence, attribution, residual, and lesson |

Save the broker confirmation and reconcile it with the order and account statement. Keep broker-confirmed facts separate from model outputs. Greeks, IV, probability, and P&L attribution depend on inputs and methods; record their provider, timestamp, and version. Never edit an original thesis after the outcome—append a dated update.

Review process and outcome on separate axes: thesis quality, contract fit, size, execution, risk handling, and rule compliance. Aggregate by setup only after fields and definitions are consistent. Include rejected and unfilled ideas to reduce survivorship bias.

## Worked journal entry

A `$50,000` account limits one thesis to `1%`, or `$500`. The journal records two Calls bought at `$2.20`, a 100 multiplier, `$440` premium, and `$4` opening fees, for `$444` initial cash at risk. At entry the option is quoted `$2.10/$2.30`, has 35 days remaining, model IV `32%`, and model Delta `0.45`. The thesis expects the stock to reach `$107` from `$100` within 10 days; invalidation is a specified business event, not an option-price stop.

After 10 days the stock is `$105`, but IV is `24%` and the option is sold at `$1.80`; another `$4` fee applies. Gross option P&L is `($1.80-$2.20)×100×2 = -$80`, and net cash P&L is `-$88`.

A same-model attribution estimates `+$180` from the underlying move, `-$180` from volatility, `-$70` from time, and `-$10` from curvature and interactions, totaling `-$80` before fees. This decomposition is an estimate, not a confirmed fact. The review can mark sizing and execution as compliant while marking the magnitude thesis wrong. A losing outcome does not automatically make the process failure, and a correct direction did not guarantee option profit.

## Review errors and controls

- Screenshots without timestamps, timezone, size, or full symbols cannot reliably reconstruct a decision.
- Last and midpoint are not necessarily executable; preserve Bid, Ask, size, package price, and actual fill.
- Do not merge a roll into one trade: record the closing realization and new opening separately, then maintain a thesis-level total.
- Assignment or exercise creates stock or cash entries that must reconcile with the option ledger.
- Percentage return needs a declared denominator: premium, defined maximum loss, stress capital, or account equity are different.
- Small samples and overlapping trades do not establish an edge; report counts, dispersion, tail losses, and rule changes.
- Protect personal and account data in exports; the journal need not expose account numbers or identifying information.

## Common misconceptions

**“A screenshot and final P&L are enough.”** They omit the prior thesis, executable quote, size, model state, cash obligations, and later decisions.

**“Every loss needs a new rule.”** Changing rules after each outcome overfits noise; revise only with documented evidence and version the change.

**“P&L attribution proves causation.”** It is a model reconciliation whose result changes with model, inputs, and interaction convention.
