From today, Proform Premium includes the System Builder on RaceMetrics — a full betting-system back-tester that runs in your browser, on any device: Windows, Mac, tablet or phone.
Everyone has a hunch. Class droppers in handicaps. Front-runners on soft going. The trainer who comes alive in autumn. The question was always the same — would it actually have made money? Now you can know.
Build it
Describe the bet in plain English and Ask RaceMetrics drafts the rules for you. Tick proven Bet Finder buttons — every button from the desktop Bet Finder is in there with exactly the same definitions. Or build rule by rule from more than 400 filters, covering everything from going and class to sectionals, ratings and the markets.
Back-test it
One click tests your rules against every British and Irish run since 2018, at real Betfair prices, with commission accounted for. Most systems back-test in a few seconds.
Prove it
You get an honest answer: profit and loss at six real prices, statistical significance, more than 150 breakdowns showing exactly where the edge lives, and ten staking plans run head-to-head before you risk a pound. A hold-out check tells you whether the system still works on the most recent twelve months.
Follow it
Save a system and every morning it reads the day's declarations — every qualifier lands on one page, arrives by email, and is flagged on every racecard.
Included with Proform Premium
The System Builder is part of Proform Premium — one subscription covering the full Proform desktop software for Windows and complete access to RaceMetrics online. If you're already a Premium member, it's live in your account now: open the System Builder and build your first system.
