A horse racing betting strategy that holds up is a process, not a stream of tips: price each runner yourself, take only prices above yours, stake small and record every bet. Check your price against the Betfair exchange near the jump before you bet, and judge your record against the Betfair Starting Price (BSP) rather than a few results. No method makes a runner win: a runner whose fair price is $6.00 still loses five races in six, so a strategy decides which prices you take, how much you stake and how you find out whether it works.
Racing in Australia suits this because a runner usually carries a price at several bookmakers and on the exchange, so you can compare before you bet and measure afterwards. The bet types and settlement rules the method sits on are mapped in horse racing betting. Each way and quaddie bets start from the same estimate of each runner's chance, with their own maths in each way betting strategy and quaddie strategy.
Step 1: frame your own price first
To frame a price, turn your view of a runner's chance into odds: fair price = 1 / estimated chance. Your view of the chance comes from the form: recent runs, class, the track rating, the barrier, the weight and how the race is likely to be run, which how to read a form guide works through.
Rate a runner a 20% chance and your price is 1 / 0.20 = $5.00, so any price above $5.00 beats your number. Framing a whole field so the chances add to 100% is a job of its own, worked through in how to frame a market.
Three habits keep a frame honest:
- Write your price down before you look at the market. Once you have seen $4.50, it is hard to rate the runner as a $6.00 chance.
- Treat your price as an estimate with error. If you rate a runner at 20% and the truth is 17%, your fair price was really 1 / 0.17 = $5.88, and a $5.50 you took as value was below fair.
- Compare with the best available price, not the first one you see. On a $20 bet, $5.00 instead of $4.60 is $20 x 0.40 = $8 more on every winner.
Risk: Betting involves risk. The top price on the day still loses when the runner loses, and a frame that beats the market on paper can still be wrong. See responsible gambling for limits and support.
Step 2: check your price against the exchange near the jump
The Betfair price near the jump makes a good fair-price check for three reasons:
- It carries no built-in margin. Backers and layers set the prices and the exchange takes commission on net winnings instead, so a race's prices add up to close to 100%, while a bookmaker's add up to more.
- It is two-sided. A price that looks too long gets backed and one that looks too short gets laid, by people risking their own money.
- By the jump it holds the most matched money and the latest news, from scratchings to track changes.
It is still an estimate, and a thin market with a wide gap between back and lay prices says less, which the exchange price as fair odds explains.
With illustrative prices for four runners in one race:
| Runner | Your price | Best bookmaker price | Exchange near the jump | Decision |
|---|---|---|---|---|
| Runner 2 | $3.40 | $3.70 | $3.55 | Bet: 8.8% above your price, 4.2% above the exchange |
| Runner 5 | $6.00 | $7.50 | $8.20 | Pass: the exchange rates it longer than the bookmaker does |
| Runner 8 | $11.00 | $10.00 | $10.50 | Pass: below both |
| Runner 9 | $4.80 | $5.50 | $5.30 | Bet: 14.6% above your price, 3.8% above the exchange |
The working for Runner 2: 3.70 / 3.40 - 1 = 8.8% and 3.70 / 3.55 - 1 = 4.2%. For Runner 9: 5.50 / 4.80 - 1 = 14.6% and 5.50 / 5.30 - 1 = 3.8%.
Runner 5 looks 25% above your price (7.50 / 6.00 - 1), but the exchange at $8.20 puts it below fair: 7.50 / 8.20 - 1 = -8.5%. When your frame is the one out of line, recheck the frame before you bet. The edge and expected value maths is set out in value betting on horse racing, and the same comparison drives positive EV betting.
Risk: Betting involves risk. A price above your estimate and the exchange's can still lose, and often does, and both estimates can be wrong. See responsible gambling for limits and support.
Step 3: stake for long losing runs
Racing results swing hard because in any race at most one runner can be more likely to win than lose. Assuming each runner's chance is exactly 1 / price, this is how long losing runs get over 500 bets:
| Price you bet at | Chance of winning | Typical longest losing run in 500 bets | Chance of a run of 20 or more | Chance of a run of 30 or more |
|---|---|---|---|---|
| $3.00 | 33.3% | 13 | 4.7% | 0.1% |
| $6.00 | 16.7% | 26 | 90.2% | 28.9% |
| $11.00 | 9.1% | 43 | over 99.9% | 95.1% |
Figures from a simulation of 20,000 sets of 500 bets each, checked against the exact calculation; typical means the middle result. Over 500 bets at $6.00, a run of 26 losers is not bad luck: it is the typical worst stretch.
On flat stakes, that worst run costs its length times your stake, as a share of your starting bank. At $3.00 and 2% stakes it costs 13 x 2% = 26%. At $11.00 it costs 43 x 1% = 43% at 1% stakes and 43 x 2% = 86% at 2%. Losing streaks in betting shows how to size stakes around the runs you can expect.
So the longer your usual price, the smaller your stake needs to be. Keep a bank you can afford to lose apart from other money, stake a fixed small share of it, and set a deposit limit at each bookmaker as a hard cap.
Staking plans compares flat, percentage and Kelly staking. Kelly is a formula, which the Kelly criterion calculator works out for one bet, and staking a quarter or a half of it is common. No staking plan turns bets priced below fair into winners.
Step 4: record every bet and check it against BSP
Record each bet when you place it: date, meeting, race, runner, bookmaker, price taken, stake, your own price, the exchange price at the time, BSP and the result. BSP is the exchange's starting price, set at the jump, which makes it the exchange market's final view of each runner. The check is closing line value (CLV):
CLV = price taken / BSP - 1
An illustrative log of five $10 win bets:
| Bet | Price taken | BSP | CLV | Result |
|---|---|---|---|---|
| 1 | $3.80 | $3.50 | +8.6% | Lost, -$10 |
| 2 | $7.00 | $7.60 | -7.9% | Won, +$60 |
| 3 | $11.00 | $9.20 | +19.6% | Lost, -$10 |
| 4 | $4.40 | $4.10 | +7.3% | Lost, -$10 |
| 5 | $2.70 | $2.74 | -1.5% | Won, +$17 |
The average CLV is (8.6 - 7.9 + 19.6 + 7.3 - 1.5) / 5 = about +5.2%, and the log is $47 ahead, yet both winners were bets that took a price below BSP. Five results say almost nothing about a method; prices that keep beating BSP over hundreds of bets are better evidence. Closing line value in racing covers why BSP works as the benchmark and how to adjust it for exchange commission.
Note: Past results are no guarantee of future results. A record that beats BSP shows your prices were good, not that the next bet wins.
What does not work
Chasing losses
Chasing means raising the next stake to win back what you have lost. Say you back runners at $3.00 and, after each loss, stake enough that one winner gets back everything lost and still leaves you $20 ahead, the profit your first $10 bet would have made:
| Bet | Stake | Total lost if this bet loses | Chance every bet to here loses |
|---|---|---|---|
| 1 | $10.00 | $10.00 | 66.7% |
| 2 | $15.00 | $25.00 | 44.4% |
| 3 | $22.50 | $47.50 | 29.6% |
| 4 | $33.75 | $81.25 | 19.8% |
| 5 | $50.63 | $131.88 | 13.2% |
| 6 | $75.94 | $207.81 | 8.8% |
| 7 | $113.91 | $321.72 | 5.9% |
| 8 | $170.86 | $492.58 | 3.9% |
Each stake is (total lost so far + 20) / 2, and the chance is 2 / 3 raised to the bet number: for bet 3, 8 / 27 = 29.6%. The prize stays $20 while the amount at risk climbs past $490. The losing-run table above puts the typical longest run at 13 over 500 bets at $3.00, and the 13th stake in this sequence would be $1,297.46.
Chasing raises what each loss costs without changing any runner's chance. The martingale betting system works the same way and fails for the same reason. If you notice it in yourself, stop for the day, and read chasing losses.
Systems and tips that promise winners
A system is a set of rules for picking bets, and it can be tested like any other: run it on paper or with small stakes, record the prices against BSP, and judge it on a few hundred bets. Staking systems such as Fibonacci and Labouchere are put to the test in betting systems that don't work.
Be wary of anyone selling one with promises of winners or an income. Scamwatch, run by the ACCC, warns that sports investment schemes, which often involve buying prediction software or joining a betting syndicate, are a form of gambling rather than an investment, and that many are scams (checked October 2026).

Where B337 fits
On the Terminal, racing and sports prices from 40+ bookmakers sit in columns, with the best available price on each runner picked out. Beside them sit Betfair back and lay, price history (flucs), closing lines (the last prices before the jump) and EV overlays against an estimated fair price. Closing lines are not BSP, so step 4's check against BSP still needs the exchange's own starting price.
Prices are read on a repeating cycle, so confirm the price in your bookmaker account before you bet. Betfair prices, closing lines and EV overlays start at Terminal View, as the pricing page sets out; a free account opens a limited view of the Terminal with live odds.
The horse racing betting bot page covers Classic Racing, which does step 2 in software. Near the jump it checks each bookmaker's win price against Betfair for the same runner and bets in your own account only when the expected value clears the edge threshold you set. It is a price comparison, not a form guide: it does not rate runners or pick winners.
Classic Racing bets only while the bot runs on your computer, which has to be on, awake and online. It needs Full Automation, set up with the team with the price confirmed before you pay, and its bets use credits. Many bookmakers restrict automated betting in their terms, and a bookmaker can limit stakes, void bets or close an account. Betfair is a trade mark of its owner, and B337 is not affiliated with it.
Risk: Betting involves risk. A price comparison shows where the value may be, not which runner wins, and automation can bet far more, far faster, than by hand: put a deposit limit on each bookmaker account before a session starts.
