BTTS is the most misunderstood market on the coupon. People price it off goals scored. We price it off two things: shot volume conceded, and how a side behaves once it goes a goal behind.

Chasing sides are the goldmine

A team that pushes its full-backs high the moment it concedes is a BTTS engine, regardless of how many goals it has scored this month.

When to leave it alone

Derby fixtures, relegation six-pointers, and any first leg of a two-legged tie. Caution kills this market.
