Ema Crossover

Simple, reliable trend follower — buys when the fast EMA crosses above the slow EMA and sells when it crosses below. Great as a first bot to try your platform.

What it demonstrates: ind.add usage, cross detection, order placement with percent amounts.

When to use: Ideal for trending markets.

const amountPercent = '5%';

function setup() {
  ind.add({
    name: "ema",
    alias: "ema_fast",
    inputs: ["close"],
    options: {
      period: 9
    },
    display: false
  });
  ind.add({
    name: "ema",
    alias: "ema_slow",
    inputs: ["close"],
    options: {
      period: 21
    },
    display: false
  });
}

async function update() {
  if (ta.crossup('ema_fast', 'ema_slow')) {
    await order.buy(null, amountPercent);
  } else if (ta.crossdown('ema_fast', 'ema_slow')) {
    await order.sell(null, amountPercent);
  }
}
