Las plataformas de cobertura de estabilidad

El programa cambia automáticamente el tipo de cambio, las tarifas, los pedidos de referencia a un precio de compra y venta, tenga en cuenta que esto no es un movimiento, es una cobertura! Este modelo de cobertura no importa si el precio de la moneda sube o baja, sólo se diferencia. Para construir un almacén se necesita un depósito de dinero, un depósito de moneda, por ejemplo, BTC ahora tiene un precio de 6000, un intercambio tiene un precio de 3000, un depósito de alrededor de 0.45 de moneda es suficiente, o el doble de todo. MaxDiff es el precio mínimo de la plataforma. SlidePrice es el precio de movimiento en el momento de hacer el pedido, el pago se suma a este precio, el pedido de venta se restará este precio. TickIntervalS indica el ciclo de detección Si el valor de la moneda cae hasta este precio, no se opera, y si la moneda de valor de la moneda de parada es mayor que este precio, no se opera, lo que evita que la plataforma le dé un golpe malicioso al robot.
