Tracking your bets means writing down, for each one, what you'll need to review it later: date, sport, market, selection, odds taken, stake, result. From those columns you can work out net profit, total staked, average odds and ROI (covered on its own page). Strike rate on its own tells you very little: it only makes sense next to the odds the bets were placed at.
What to keep from every bet
Tracking your bets means keeping what you need to review each one: the odds taken, the stake, the market, the result. Without those columns, your history is just a balance going up or down.
A record gives you three things a bank statement doesn't. You relate the result to the amount staked. You tie each bet to the price you took it at. You tell a run from a trend.
A betting record is a sequence of decisions taken at different prices. Each result only makes sense once you know the price behind it.
Why the bookmaker's history isn't enough
An operator's interface shows your balance, your open bets and your settled bets. It isn't built to compare periods, sports or markets. The data is there, but nothing lets you aggregate it.
There's a more down-to-earth reason too. As soon as your bets are spread over two or three accounts, the only place the full record can live is a table you keep yourself.
The data to record for every bet
One row per bet, eleven columns at most. The first nine are the foundation. The last two are optional, but they change a lot about how you read the record back.
| Column | What you write down | What it's for |
|---|---|---|
| Date | The day of the bet, not the day it settled | Rebuilding the timeline |
| Sport | The discipline | Isolating what behaves differently from one sport to another |
| Competition | The league or tournament | Levels differ in liquidity and in margins |
| Market | Winner, total goals, handicap | Two markets on the same match can't be compared |
| Selection | The exact outcome the bet is on | Knowing exactly what was played |
| Odds taken | The odds at the moment you confirmed | Keeping the real price of the decision |
| Stake | The amount committed to that bet | Relating profit to volume |
| Result | Won, lost, void or refunded | Counting the bets |
| Profit / loss | The net result, negative when the bet loses | Adding up net profit |
| Closing odds (optional) | The odds on the same selection just before kick-off | Measuring the quality of the price you got |
| Notes (optional) | The reason for the bet in one sentence, written before the result | Reading yourself back without rewriting history |
The last column, Notes, makes you write your reason down before you know the outcome. Read back weeks later, a dated sentence beats your memory of it.
A £10.00 bet on a selection priced at 2.20, lost.
Odds taken: 2.20 · Stake: £10.00 · Result: lost · Profit / loss: −£10.00.
The same bet won would have returned £22.00, a profit / loss of +£12.00.
The metrics these columns give you
Those columns are all you need to calculate everything. That's why you fill them in at the moment of the bet, not afterwards.
| Metric | What it tells you |
|---|---|
| Number of bets | The denominator of almost everything else |
| Total staked | The sum of every stake, winning bets included |
| Net profit | The sum of the profit / loss column, the one figure that says what happened to your balance |
| Strike rate | The share of bets won. Useful, but never on its own |
| Average odds | The mean of the odds taken, which makes the strike rate readable |
| ROI | Worked out from net profit and total staked, covered on its own page |
| Runs | The longest sequence of wins and the longest sequence of losses |
| Closing line value | The gap between the odds you took and the closing odds |
"The higher my strike rate, the better my performance."
A strike rate only reads alongside the prices the decisions were taken at. On its own it doesn't say whether a run of bets made or cost money, and it can rank two records the opposite way round from their net profit.
The ROI calculation, the break-even point by odds and the comparison of two records with the same strike rate are covered on their dedicated page.

Runs, volume and the limits of tracking
A long losing run is nothing unusual. It comes with any sequence of bets, and it gets longer as the odds rise. Around 2.50, six or seven losses in a row isn't exceptional.
The runs column is there to put a record in context, never to judge it. The same goes for volume: over a few dozen rows, most of what you see comes down to luck. Careful tracking doesn't change that.
A positive ROI over thirty bets doesn't show that a method works. A negative ROI doesn't show that it fails.
Closing line value: judging the price you got
Every metric above depends on what happened on the pitch. Closing line value is the exception. It compares the odds you took with the odds on the same selection just before kick-off, once the market has absorbed all the available information.
Take a selection at 2.20 and watch it close at 2.00, and you got a better price than the market's final one, whether the bet then wins or loses. It tells you about the decision, not about its outcome.

What tracking can tell you
A record lets you rebuild a complete history, isolate a sport or a market, measure an ROI and spot a run. Set against the closing odds, it also gives you a sense of the quality of the prices you got over time. It never shows that a method is profitable, that a past result will repeat or that a positive record predicts anything at all.
A spreadsheet is enough for all of it.
Measuring assumes you've settled what you're committing. Your budget and the size of your stakes get decided before the first bet, not when you review the record.

Which data should you record for every bet?
At the very least, the date, sport, competition, market, selection, odds taken, stake, result and profit or loss. The closing odds and a free note on your reasoning are optional, but they help a lot when you look back.
Why isn't the strike rate enough?
It counts the bets you won without looking at the price you took them at. A record with a 50% strike rate on odds of 1.50 and another with 40% on odds of 2.50 don't rank the way those percentages make you think.
Where can you calculate and read the ROI of your tracking?
The ROI calculation and how to read it have their own page, on profitability. Here, the focus is on what you need to record to calculate it properly.
How many bets does it take for a record to be readable?
No threshold makes a record conclusive. Over a few dozen bets, most of what you see is still down to luck, and that doesn't flip suddenly at a particular number.
Does a losing run mean the method is bad?
Not necessarily. Long runs turn up naturally in any sequence of bets, especially at long odds. A run is something to note, not a diagnosis.
Should you record the closing odds?
It's optional, but it's the one column that describes the quality of the price you got without depending on the result of the match. Comparing the odds you took with the closing odds is what's called closing line value.
Is a spreadsheet enough to track your bets?
Yes. A spreadsheet with one row per bet and the columns on this page lets you calculate every metric mentioned here, with no dedicated tool.
Sources and method
This page describes a tracking method rather than a thesis to source. The idea of the closing price as a benchmark draws on academic work on sports betting prices, including the study cited below. The rest comes from OddScore's odds-analysis methodology. The Gambling Commission and BeGambleAware links cover responsible gambling.
- List the minimum data needed to recalculate a record (date, market, selection, odds, stake, result), with no judgement on performance.
- Treat strike rate on its own as insufficient, always to be read alongside the odds and the volume.
