Several factors can shift trader positioning before the match begins. Recent form and head-to-head records between Angelini and Castagnola often trigger repricing as bettors incorporate new data.

Betting action from sharp traders or institutional flow may also signal information asymmetry. As the match start time approaches, late-breaking news about player fitness or tactical adjustments typically drives final volatility in this market.
