Frequently Asked Questions — Tennis Odds Line Movement
What does line movement mean in tennis betting?
Line movement refers to a change in the odds offered by a bookmaker between the time a market opens and when it closes just before the match. On this page, OPEN shows the initial Pinnacle price and CUR (or CLOSE on archive pages) shows the final price. The Δ% column shows the percentage change. When odds shorten (Δ% is negative for the favourite), it typically means money has come in on that player. When odds drift (Δ% is positive for the favourite), the market is moving against them.
Why does Pinnacle move its lines?
Pinnacle adjusts its odds for two main reasons: to balance its liability (equalising the money on both sides) and to reflect new information — such as injuries, sharp bets, or updated statistical models. Because Pinnacle accepts sharp (professional) bettors without restricting them, its line movements are considered more meaningful than those of recreational bookmakers. A significant Pinnacle line move is widely regarded as one of the most reliable pre-match signals available to the public.
How is the percentage change calculated on this page?
The Δ% figure is calculated as ((CUR − OPEN) / OPEN) × 100. A positive Δ% means the price rose from the opening — the player's implied probability decreased in Pinnacle's view. A negative Δ% means the price fell — implied probability increased. This is calculated on the raw decimal odds, not converted to any other format. All data is sourced directly from Pinnacle's live and historical odds feed.
