How the Market Line Labs record is graded and verified

The Market Line Labs record counts exactly what members received: every released pick, at the number and size in the alert, graded after the final. Each pick is also sealed in a public hash chain when it's released, so anyone can check nothing was changed afterwards.

What counts

  • Released picks only. If members received it, it's on the record. Nothing is added later and nothing is removed.
  • The posted number. Each pick is graded at the line and price in the alert, never at a better number found later.
  • The recommended size. Units won or lost use the size in the alert, so a 2-unit pick counts twice as much as a 1-unit pick.

Pushes, voids and overtime

A push (the result lands exactly on the number) returns the stake and counts as neither a win nor a loss. A game that is postponed or cancelled isn't graded and doesn't count toward the record. Full-game picks include overtime, and second-half picks include overtime as well.

Closing-line value

Every graded pick also records the closing line, so you can see whether the released number beat the market's final price (what CLV means).

Sealed at release, checkable by anyone

When a pick is released, its details are hashed (SHA-256) and the fingerprint is published straight away, chained to the fingerprint before it. Once the game is graded, the details are revealed next to the fingerprint. Anyone can recompute every hash and confirm the chain is unbroken, and each day's latest fingerprint is recorded as a daily anchor. Try it on the verification page.

Backtests are labelled

Results from earlier seasons are backtests: the current rules applied to past games. They're hypothetical, always labelled, and never mixed into the live record.
