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 begins. 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 generally 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 injury news, sharp bets, or updated statistical models. Because Pinnacle accepts sharp (professional) bettors without restricting their accounts, 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 — implying Pinnacle's view of that player's win probability decreased. A negative Δ% means the price fell — implying their win probability increased. This is calculated on raw decimal odds and is not converted to any other format. All data is sourced directly from Pinnacle's live and historical odds feed.
