A ticket marked “football, won” is not much of a record. A month later, you will not remember the handicap, the odds or whether you backed the team before its striker was ruled out. A useful journal preserves the decision you actually made.

Quick answer: Start with the event, market and line, odds, stake, timestamp, original reason, settlement, total return and net result. Add a closing-price reference only if you can collect it consistently.

The sample entry below is invented. You can practise the entire routine using paper selections without staking money.

Keep the first version small enough to maintain

Use a spreadsheet or notebook with these fields. The aim is an honest record, not a dashboard that takes longer to fill in than the research itself.

  • Event and scheduled start, including time zone.
  • Selection, exact handicap or total, and market period.
  • Bookmaker or exchange and decimal odds actually accepted.
  • Stake in currency and, if useful, a consistently defined unit.
  • Placement time and the reason written before the result.
  • Result, settlement type, total return and net profit or loss.
  • Fees or commission, plus any void, cash-out or promotion.
  • A short review note kept separate from the original reason.

For a journal, “Team A” is not a complete selection. “Team A -0.25, full match, 1.90” records the settlement condition as well as the price.

Fill in one fictional row

Imagine a 10€ paper stake on Team A -0.25 at 1.90. The reason might be: “Home side creates stronger chances, but away defensive improvement makes a draw plausible.” Record the evidence source and any missing information alongside that sentence.

The match finishes 1–1. Enter “half-loss,” a total return of 5€ and a net result of minus 5€. Do not mark it simply as lost and assume every losing ticket costs the full stake.

Keep the original explanation unchanged. In the review field, you might write: “I acknowledged the draw but did not compare the 0.0 price.” That is a process observation you can use next time, not a story about bad luck.

Calculate results without counting deposits as profit

Net result equals total return minus stake minus charges not already deducted. Across several selections, yield is total net result divided by total stakes, multiplied by 100.

For example, if completed tickets total 200€ in stakes and return 190€ after all applicable charges, the net result is minus 10€ and yield is minus 5%. A new deposit does not improve that performance.

Keep cash-out transactions clearly labelled. Do not both count the cash-out return and later add a theoretical final settlement for the same ticket.

Review decisions rather than only winners

Choose a regular review date, such as once a week, without treating a week as enough evidence of skill. Look for avoidable issues: wrong lines, prices taken after a large move, missing team news, or bets made outside your own limits.

Separate markets only when there is enough data to make the split useful. Three successful over-goals bets do not validate a strategy. Likewise, a short losing run cannot tell you by itself whether the original reasoning was sound.

Include every selection. Quietly deleting impulsive bets gives you a flattering record of a bettor who does not exist.

Should I record bets I decided not to place?

You can keep a separate paper-research tab with the same timestamps and market details. Never mix hypothetical returns with real settled results. The separation helps you learn without implying that an available price was actually accepted.

Do I need closing odds from day one?

No. A complete basic record is better than a complicated incomplete one. If you add closing odds, define the source and collection time first and compare the exact same market.
