Gecko Edge works off live data, and the calculations update as new data becomes available. EV is the gap between the model’s fair price and the bookmaker’s price at the moment you run the analysis, and both sides of that comparison move. The bookmaker shortens or drifts a line through the day, and the model takes in new information, so the same market can read negative in the morning and positive a few hours later, or the reverse. The teams have not changed; the inputs have.
Three things move the number between two readings of the same fixture. The bookmaker’s price is the most visible: as money goes on a line, the price moves, and that alone can flip the EV. The model’s inputs update as team news and line-ups come in closer to kick-off. And each analysis is a fresh calculation of the current state, so a re-run gives you the current picture rather than a saved one.
Act on the reading that is current when you decide. And remember the other side of this: a bet is +EV at the time you take it. If the analysis showed value at the price you took, you have locked that value in, and whatever the EV does afterwards is irrelevant to that bet.
