How it works

What you'll see on a race card, and how to read it.

Start with the highest-rated horse in each race. That's the runner marked ★ Top Rated, the one we think has the best chance of winning. Then compare our fair price with the available odds and read the reasons behind the rating.
We estimate every horse's chance of winning and turn it into a fair price. When the available odds are bigger than our fair price, we flag potential value.

Anatomy of a race card

Here's what you'll see for every runner. The value flag is the green one.

#: our rank. The model's order, where 1 is the horse we rate most likely to win.
2
Model Chance. Our estimate of the horse's chance of winning. Over time, horses we rate at 30% should win about 30% of their races, and we publish how close we are.
3
Market Implies. The chance the price suggests. Odds of 4/1 mean a 1-in-5, or 20%, chance.
4
Average price. The typical price across 20+ bookmakers, updated through the day, so one unusual bookmaker can't create the value on its own.
5
▲ Edge increasing / ▼ Edge decreasing. Green means the odds have lengthened since this morning; red means they have shortened. A price moving doesn't change our rating of the horse, and the market may know something we don't.
6
Value. How much bigger the available odds are than our fair price. Green means potential value; grey means none.

Reading it: value vs no value

Value
Example Lad. We rate its chance at 32%, but odds of 4/1 imply only 20%. Because the odds are bigger than our fair price, it's flagged as +60% value. It can still lose.
No edge
Market Darling. We rate its chance at 25% and odds of 11/4 imply 27%, so the market has it about right. No value is flagged.

Then make it yours: My Slip

Members
Tap + Slip on any runner to build your day's slip: singles, each-way, doubles and trebles at your own stakes. For each bet we show our estimated chance against the price you're getting, including combined bets. The slip then settles itself from the official results, so your personal track record builds day by day, with wins, losses and voids all included.

The honest bit

A horse flagged as value can still lose, and most horses do. EdgeDigger gives you the ratings, fair prices and reasons so you can make your own choice. We don't promise profit, and we publish exactly how accurate we are, including where we're wrong.
