Grade limits apply: D from the weaker of liquidity and integrity, C+ from trading evidence.

Some data was missing in this period, so no grade change can be confirmed until it recovers. Gaps are never filled in.

Rates how well this market trades, from A+ (best) to F: how much you can trade near the price, and how many different traders take part. Not a forecast of the outcome.

Liquidity and integrity

The two measures behind the grade.

Liquidity

Not rated

How easily the market trades: the depth of buy and sell quotes, the cost of a typical trade, and how steadily trading happens.

Integrity

Not rated

How broad and orderly trading is: how many different traders take part, and how often quotes are missing, one-sided, or crossed.

It screens for concentrated trading. It is not proof that a market can’t be manipulated, since many accounts can belong to one trader.

Both are recalculated daily over the same 30-day period. The overall grade moves more slowly: a change has to hold before it counts.

How grades are calculated ↗

Market Grades are in beta. Grades are live, and the methodology is being validated in public on a published schedule. Validation roadmap ↗

Disclosures

Market Grades measure market quality – liquidity, integrity – not the likelihood of any outcome.

Market Grades are unsolicited: no graded party requests, pays for, or previews a grade. Belief Systems holds no positions in graded markets.

A grade is not a recommendation to buy, sell, or hold any position, and is not a substitute for a user's own assessment.
