FeaturesAlerts & conditions

Crypto wick detection, for the spikes that don't hold.

A long wick means price spiked and was slammed back before the candle closed — a rejected move, often the first sign of a turn. CoinBeacon checks every candle close and pings you only when a wick is genuinely out of the ordinary.

Wick detection

See what the candle is hiding.

A wick is the thin line above or below a candle’s body — price pushed there, and the market pushed straight back before the close. Long wicks mark rejected moves, and rejected moves often mark turning points. CoinBeacon measures every close so you hear about them in seconds.

  • Upper or lower. Watch for spikes up that got sold into, or dips down that got bought straight back — either side of the candle is its own condition.
  • Percentile-calibrated. No fixed size rule: the threshold adapts to each coin’s own candle history, so only wicks that are unusual for that market and timeframe count.
  • Your timeframe. Run the check on 1-minute closes for scalps or daily closes for swing entries — wick detection is one of CoinBeacon’s 11 indicator alerts.

How a wick becomes an alert

  1. 01

    Measure on close

    When a candle closes, CoinBeacon compares the wick — how far price spiked beyond the body — against the body itself. A spike that closes back inside the range leaves a long wick: the footprint of a rejected move.

  2. 02

    Calibrate by percentile

    “Long” is relative, so thresholds are percentile-calibrated against each coin’s own recent candles on your timeframe. A wick has to be genuinely unusual for that market to fire; routine noise never does.

  3. 03

    Deliver once

    The moment a wick clears the bar, one notification goes out — email, Telegram, Discord, or a JSON webhook. A per-alert cooldown keeps a choppy session from re-pinging you on every candle.

Wick detection — questions

What is a wick alert in crypto trading?
A wick alert fires when a candle prints an unusually long wick — price spiked past the body and snapped back before the close, the signature of a rejected move. On CoinBeacon you pick the coin, the side (upper or lower), and the timeframe; the check runs on every candle close.
How does CoinBeacon decide a wick is significant?
Thresholds are percentile-calibrated against each coin's own recent candles rather than a fixed size, so a wick has to be genuinely unusual for that market and timeframe to fire. Per-alert cooldowns stop a choppy session from re-pinging you on every candle.
Is wick detection included in the free plan?
Yes. Every CoinBeacon feature is included free — 10 active alerts, 10 notifications per day, Google sign-in. Wick detection is one of 11 indicator alerts alongside RSI, volume, EMA, MACD, Bollinger, Stoch RSI, OBV, ADX, VWAP, and market cap, and it delivers to email, Telegram, Discord, or webhook.
