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