股票与 ETF — Volume Spike

Unusual Volume & Market Participation

A volume spike measures unusual market participation, not direction by itself. It flags when trading activity is significantly higher than a recent baseline — often the first sign that something meaningful may be happening in a market.

Current Volume vs Average Volume

This screener compares current volume with a recent average volume baseline. Large deviations often reflect stronger participation, institutional activity, or event-driven flows.

What is Volume Spike Ratio?

Spike Ratio compares current trading volume with its recent average. A ratio of 2.0 means current volume is approximately twice the reference volume; 3.0 indicates roughly three times normal activity.

Volume Spike + Price Direction

A positive price change alongside unusually high volume may indicate increased buying participation, while a negative price change with elevated volume may indicate stronger selling pressure. Volume alone does not determine direction.

LONG / SHORT Interpretation

Directional LONG or SHORT classifications require confirmation from accompanying price action. Long setups often appear when volume surges while price pushes higher. Short setups often appear when volume surges while price breaks lower.

Multi-Timeframe Confirmation (15m, 1h, 4h, 1d)

Lower timeframes help identify early volume surges; higher timeframes provide regime context. A robust volume-spike workflow often confirms the setup across at least two timeframes.
