First, a definition: Volume spikes over short periods can be noisy. A spike in one or two candlesticks may simply be caused by a single large order; several consecutive high-volume candles are more convincing.
Next, how to interpret it: A rise on high volume is often seen as an advance supported by trading activity, while a fall on high volume is often interpreted as genuine selling pressure—but these are just rules of thumb.
All data describes past market movements, and the market can turn in the opposite direction at any time.
