Volume Spike
A volume spike is a sudden jump in trading activity far above a market's normal level. It means participation changed — new money, new information, or forced reactions arrived at once. Spikes mark the moments worth examining, but a spike by itself says something is happening, not which direction it will resolve.
What causes a sudden volume spike?
Common triggers: news and listings (an exchange listing announcement, a partnership, a hack), technical breaks (price crossing a widely watched level, triggering clustered stops and breakout entries), cascading liquidations in derivatives spilling into spot, coordinated activity (pump groups concentrate on thin coins precisely because little capital moves them), and large single participants executing size. The context that matters most is the baseline: raw volume is meaningless across coins, so a spike is properly measured relative to that market's own typical volume — the same notional turnover is an ordinary hour for BTC and an extraordinary event for a small altcoin.
Is a volume spike bullish or bearish?
Neither, by itself — volume measures intensity, not direction. Every trade has a buyer and a seller; what distinguishes outcomes is who was aggressing and what price did under the pressure. A spike with price surging and holding its gains reads very differently from an identical spike where price spikes and immediately retraces (a classic pump-and-distribution signature), or one where heavy selling meets a level that refuses to break (possible absorption). Useful practice pairs the spike with direction-aware measures — taker buy/sell balance, whether the move held, what the order book did — before drawing any conclusion.
