Volume Spike Scalper

Detects sudden volume spikes relative to average and follows the direction of the candle — quick entries and exits.

const lookback = 20;
const volMultiplier = 3; // enter if current volume > avgVolume * volMultiplier
const amountPercentage = "5%";

function setup() {
  // no extra ind needed
}

async function update() {
  // get average volatility/volume via helper - we have getVolatility but it's usually for price; for volume use simple average via candle.last
  const lastCandles = candle.last(lookback);
  // Wait until there is enough data
  if (lastCandles.length !== lookback) return;
  const avgVolume = lastCandles.reduce((s, prevCandle) => s + prevCandle.volume, 0) / lookback;
  const currentVolume = candle.volume;

  if (currentVolume > avgVolume * volMultiplier) {
    // if momentum (price climb) + volume spike => buy else sell
    if (candle.close > candle.prev().close) {
      await order.buy(null, amountPercentage);
    } else {
      await order.sell(null, amountPercentage);
    }
  }
