Esta estrategia replica el comportamiento de un spreader de alta frecuencia en el mercado FORTS. Monitorea continuamente el libro de órdenes y coloca órdenes limitadas en ambos lados del mercado para capturar el diferencial bid-ask.
Lógica de la Estrategia
Suscribirse a actualizaciones del libro de órdenes en tiempo real.
Cuando no hay posición abierta y el diferencial es suficientemente amplio (determinado por SpreadMultiplier), la estrategia coloca:
Una orden limitada de compra un tick por encima del mejor bid.
Una orden limitada de venta un tick por debajo del mejor ask.
Si existe una posición y no hay órdenes activas, coloca una única orden limitada en el lado opuesto para cerrar y revertir la posición.
Las órdenes se cancelan y reemplazan cuando los mejores precios se mueven para mantenerlas en la cima del libro.
Parámetros
SpreadMultiplier – diferencial requerido en ticks para colocar ambas órdenes de compra y venta. El valor predeterminado es 4 ticks.
Volume – volumen de la orden. El valor predeterminado es 1 lote.
Notas de Uso
Diseñada para instrumentos con tamaños de tick pequeños, como futuros en la bolsa FORTS.
Utiliza únicamente órdenes limitadas; no se envían órdenes de mercado excepto por el mecanismo de protección si es necesario.
Asegurar suficiente liquidez y un entorno de baja latencia para una operación efectiva.
