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.

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.
