FanDuel API is an independent data service operated by FF API Inc. It is not affiliated with, endorsed by or sponsored by FanDuel.

Replay a prop or a game line from the first time it was seen to now, move by move.

Price-only moves: An over going from -110 to -125 on the same line is its own entry, so closing line value is measured on price, not only on line.
Timestamps: Every point has observed_at, the time the collector read it. Nothing is interpolated.
Open and close: The move summary gives open, current, net line move and the direction prices moved.
