Betting Journal: What to Record for an Honest Analysis
To review your decisions, record the price before the event, exact market, stake, source and settlement status—including passes and voids.
Why keep a journal
Without records, people tend to remember a few striking wins or losses but not the full set of decisions. A journal can show how often you bet, at what price, on which markets and how voids were settled. It is a recordkeeping and self-review tool, not a way to predict future results.
The central rule is to record a decision before the result. If you only considered a bet, label it as an observation rather than a placed wager. Do not add “obvious” picks after the game; that can quietly leave only favorable memories in the record.
A minimum set of fields
For each row, save:
- decision date and time, competition and match;
- exact market, outcome, line and period;
- available price and the price actually accepted, if a bet was placed;
- stake and accounting currency;
- quote source and timestamp;
- a short hypothesis and the key facts behind it;
- status: placed, passed, cancelled, void, loss or win;
- returned amount and net financial result under a pre-set rule.
If you record an analysis before placing a bet, keep it separate from the actual ticket. That lets you see where the idea differed from the available price or where the decision changed before the start. Do not overwrite the original values; note a correction as a separate event with a reason and timestamp.
Keep metrics distinct
Before calculating, define how you handle full or partial voids, refunds, commission and unsettled bets. State whether amounts are in currency or units and how results are rounded. Win rate counts the share of winning bets; ROI relates profit to the amount staked. They are different measures. See Sportexa's guides to win rate and ROI.
At a chosen interval, check for complete rows, duplicates, missing prices and arithmetic errors. Review the full pre-defined journal first, then group by sport or market. Do not delete losing months or change criteria to keep only the attractive part of a history. With few records, conclusions remain unstable.
Protect privacy and boundaries
Do not put passwords, full payment details, identity documents or unnecessary information about other people in the sheet. Protect access and share only anonymized summaries if needed. If keeping a journal becomes a reason to bet more often or chase losses, pause. The journal should help you notice behavior, not push you toward more gambling.
Make the journal auditable
Keep the original row unchanged and add a separate correction entry stating what was wrong, when it was found and who updated it. At a regular interval, check missing fields, duplicate matches and returns that do not follow the settlement rule. The table does not need to be elaborate; consistent coding matters more. Define the start and end dates before evaluating a period, include every decision in that window and mark passes explicitly. This makes it easier for another person to understand which observations were included and to reproduce the summary without guessing.
