Bollinger Breakout Scalper

When price breaks Bollinger bands with volume confirmation, enter for quick breakout scalps.

What it demonstrates: Multi-value indicators (bollinger {upper, mid, lower}),.

When to use: Useful for volatile sessions.

const amountPercentage = "15%";

function setup() {
  ind.add({
    name: 'bbands',
    alias: 'bb',
    inputs: ['close'],
    options: {
      period: 20,
      stddev: 2
    },
    display: true
  });
}

async function update() {
  const bb = ind.get('bb');
  if (!bb) return;
  // breakout logic: close > upper -> buy (momentum), close < lower -> sell
  if (candle.close > bb.upper) {
    await order.buy(null, amountPercentage);
  } else if (candle.close < bb.lower) {
    await order.sell(null, amountPercentage);
  }
}
