Originator
The sportsbook that first posts a line on a market, establishing the opening price before other books follow.
Like the primary news source vs. outlets that just reprint the same story.
Why it matters
Originator lines carry the most information because they are priced from scratch rather than copied from competitors.
How DMP uses this
DMP identifies originator prices in the consensus to give higher weight to independently derived odds.
Common mistake
Treating all books equally when building consensus -- originator lines deserve more weight.
