Market Width
The spread between the best available odds on each side of a market across all sportsbooks. Tighter width means more efficient pricing.
Like checking the spread between buy and sell prices on a stock -- tighter spread means a more liquid, efficient market.
Why it matters
Wide markets have more vig and less agreement. Tight markets mean the true price is well-established.
How DMP uses this
DMP shows market width to help users identify which props are efficiently priced vs. which have exploitable disagreement.
Common mistake
Assuming a wide market means more opportunity -- sometimes it means less information and higher risk.
