Keep a journal that preserves the original decision

The short answer

A useful journal records what you knew before an outcome, not an explanation written after a chart moved. It preserves the original decision so that later you can grade the process separately from the result.

What to capture before

• Chain and exact address, with the research timestamp.
• Primary evidence, with links and times.
• The setup and why it qualified.
• The invalidation condition, stated observably.
• Planned exposure and planned acceptable loss.
• Expected costs, and which ones are unknown.
• Reasons you might skip.

What to capture after

• Actual acquired quantity and actual fills.
• Transaction references.
• Fees paid, separated into known and unknown.
• Realised result, kept distinct from any current estimate of open value.
• Process notes: what you did that was not in the plan.
• One lesson, written as a change rather than a feeling.

Rules that keep the record honest

Blank costs are unknown, not zero. A journal that silently treats missing fees as zero will overstate every result.

A deposit is additional capital, not trading profit. Any report that mixes them is describing your bank transfer, not your trading.

Preserve currency context. If you record USD equivalents for transactions denominated in a native asset, store the conversion rate, its source and its timestamp. Otherwise the record cannot be rebuilt later.

Mark manual entries as manual. If imports are added later, keep the source and import date, because imported and typed records fail in different ways.

Review process and outcome separately

A profitable trade can involve poor preparation and accidental risk. A losing trade can follow a sensible process under uncertainty. Neither one result nor a short winning streak establishes an edge. Grading only outcomes teaches you to repeat whatever happened to work.

A practical review: group comparable setups, count the sample, inspect cost totals, isolate unusually large outcomes, and list execution problems. Then choose one concrete change — better source records, fewer high-fixed-cost trades, a required invalidation line — and apply it for a defined period.

Include what you did not do

Record skipped and missed trades. These entries show whether your filters removed genuine risk or good opportunities, and they resist the memory distortion that makes every missed move look obvious in hindsight. Keep the original plan intact and append later notes rather than editing it.

Privacy

When turning a journal entry into a public post, remove anything you did not intend to publish: wallet addresses that link your activity, position sizes, personal details, screenshots containing balances or account identifiers. Private entries should stay private by default.

What this cannot establish

A journal does not improve outcomes by itself, and a small sample of entries cannot demonstrate an edge. What it does is make your reasoning inspectable, which is the only way to find out whether your process is doing anything.

Checklist

• Pre-trade reasoning written before entry
• Observable invalidation recorded
• Actual quantities, fills and references captured after
• Unknown costs labelled unknown
• Deposits never counted as profit
• Skipped and missed trades included
• Original plan preserved; later notes appended
