Flutter Butter // Proof of Edge

We Log the Closing Price. Publicly. No Exceptions.

Anyone can show you a win. Closing Line Value is the number professional syndicates actually track — because it proves the selection was sharp, independent of how any one bet happened to land. Tracking is live from every new bet — the number below fills in as results come through.

Tracking Is Live
Every bet already logs a price the moment it's placed. The first verified number lands the moment our next race or match closes — check back soon.

// The Foundation

What Is Closing Line Value?

The closing price is the market's final, most-informed number — set right before an event starts, after every bit of public money, sharp money, and late information has already moved it. If we consistently get a better price than that final number, it means the market itself caught up to where we already were.

That is the single cleanest signal in betting. A hot month can be luck. A cold month can be luck. Beating the close across hundreds of bets, over a long run, is much harder to fake — it is the number professional syndicates use internally, because it is the one result-independent way to check whether the picks are actually sharp.

CLV Formula ((Odds Taken ÷ Closing Price) − 1) × 100

A positive number means we got the better price — we beat the market's own final assessment.
// How It's Captured

No Cherry-Picking — Every Price Is Logged Both Ways

The moment a bet is logged — win, loss, doesn't matter, before the result is known — we capture the live market price. When the event starts, we automatically capture the closing price too. Both numbers are stored the instant they happen, not selected afterwards to make a nicer chart.

The figures on this page are a live read of that same underlying data — the same numbers we check ourselves before deciding what's actually working. Nothing here is curated for this page.
