Examples

Indicator Example

script({ type: 'indicator', priceStudy: true });

const length = input.integer('Length', 14);
const value = ta.rsi(close, length);

plot(value, { type: 'line', color: '#1D4E89' });

Single-Symbol Strategy Example

script({ type: 'strategy', priceStudy: true, orderSize: 1 });

const fast = series(ta.ema(close, 10));
const slow = series(ta.ema(close, 20));

if (ta.crossover(fast, slow) && strategy.param_by_id('ema', 'position') === 0) {
  strategy.entry({ id: 'ema', type: 'long' });
}

Explicit Qty Override Example

script({ type: 'strategy', priceStudy: true, orderSize: 1 });

strategy.entry({ id: 'scaled_ema', type: 'long', qty: 5 });

const headerEntry = strategy.default_qty_type === 'con'
  ? { id: 'header_ema', type: 'long', qty: strategy.default_qty_value }
  : { id: 'header_ema', type: 'long' };

strategy.entry(headerEntry);

Multi-Symbol Example

script({ type: 'strategy', priceStudy: true });

symbols([
  'BTCUSDT:BINANCE:FUTURE:DEFAULT',
  'ETHUSDT:BINANCE:FUTURE:DEFAULT'
]);

const btcClose = symbol.close[0].get(0);
const ethClose = symbol.close[1].get(0);

if (btcClose > ethClose) {
  strategy.entry({
    id: 'btc_leg',
    type: 'long',
    symbol: 'BTCUSDT:BINANCE:FUTURE:DEFAULT',
  });
}
