TERM
Price age
The time elapsed since the bookmaker last updated a price that is part of a surebet.
A scanner reads bookmaker lines in cycles, and for every price it knows when the book last changed it. A surebet made of two prices that are 1 second old and a surebet where one leg hasn't updated for 15 seconds are different even at the same ROI: in the second case, it's more likely that the book has already changed the price and the scanner hasn't seen it yet.
In a Dozor card, the age is shown for each leg. Age matters more in live: according to data for September 6, 2026, 39% of surebets disappear within two seconds.
