How does matching work?
Matching at BetDEX works on a a FIFO (first in, first out).
In practice, this means that back orders will be matched using the highest available odds and lay orders will be matched at the lowest available odds. Orders that were placed first are first to be matched. Newer orders that are eligible to be matched are matched once older, pre-existing orders have been matched.
In the graphic below, the prices that are available for backing are in blue and the prices available for laying are in red.
If we were to place the below order...
The bet will get fully matched as there was $1,881 of available liquidity at 1.85
The available unmatched liquidity at 1.85 also decreases to $1,879
Bets/orders can also be partially matched.
If for an a user wanted to bet $2,000 on the Phillies at 1.85, $1,879 of that would be matched, and $121 would remain as an unmatched order until someone else is willing to take the other side of that bet.
