Funciones de implementación:
- Subscripciones de flujos públicos, trades y síntesis profunda
- Subscripciones de flujo privado, mantenimiento de la lista de encargos y posiciones locales, y información sobre el saldo
- Mantener el estado de cancelación de la orden fuera de tiempo, soporte para OKX amendOrders
- Soporta múltiples variedades, facilita la estrategia de alta frecuencia para operar múltiples mercados al mismo tiempo con la menor latencia
- Agregar la función EventLoop (requiere soporte de los administradores más recientes), que puede esperar a que se devuelvan datos de cualquier websocket en caso de conexiones de varios websockets, evitando las encuestas
- Apoyo a OKX y Binance Futures y a Binance Cash and Cash Leverage Trading, OKX Cash no está disponible, los interesados pueden cambiar por su cuenta
- OKX para la transmisión privada de la suscripción requiere una clave y una contraseña que se ha hecho como un parámetro escrito en la plantilla
- Automatizar algunas funciones básicas de la red, como la reconexión de cables cortados
- Retiro de eventos en apoyo de la cancelación de la devolución de pedidos de flujo privado
- Para unificar la lógica de pedidos de las dos bolsas, consulte el código fuente de la plantilla o el ejemplo
- Interfaz websocket para suscripción simultánea a varias bolsas
- La modificación de la factura de pedidos, así como la eliminación, se pueden devolver por lotes como tareas y se procesarán automáticamente las tareas de transacción.
En el caso de los pedidos de alta frecuencia, los pedidos que la bolsa devuelve no son oportunos (canales privados), pero es posible que las cosas hayan cambiado en ese momento y que necesitemos mantener un estado de pedidos localmente. Las plantillas se identifican automáticamente como OKX o Binance, aquí hay un ejemplo sencillo, y es muy recomendable leer el código fuente para poder personalizar tus propias funciones a un nivel más profundo.
Este es un ejemplo simple.
function onTick(ctx, event) {
if (event.depth) {
Log("depth update", event)
}
if (event.trades) {
Log("trades received", event)
}
if (event.balance || event.positions) {
Log("account update", event)
}
if (event.orders) {
Log("private orders update", event)
}
// include orders, positions, balance for latest
Log("account", ctx.wsPrivate.account)
// for test only
if (false) {
return {
amendOrders: [{
instId: event.instId,
clOrdId: "xxxx*****",
cxlOnFail: true,
newSz: "2",
}],
newOrders: [{
instId: event.instId,
clOrdId: UUID(),
side: "sell",
tdMode: "cross",
ordType: "post_only",
px: event.depth.asks[0].price.toFixed(4),
sz: "1",
}, {
instId: event.instId,
clOrdId: UUID(),
side: "sell",
tdMode: "cross",
ordType: "post_only",
px: event.depth.asks[0].price.toFixed(4),
sz: "1",
}],
cancelOrders: [{
instId: order.instId,
clOrdId: order.Id
}]
}
}
}
function main() {
let instId = exchange.SetContractType("swap").InstrumentID
let ctx = $.NewWSS(exchange, function(ws) {
let msg = null
if (exchange.GetName() === 'Futures_OKCoin') {
msg = {
op: "subscribe",
args: [{
channel: "books5",
instId: instId,
}, {
channel: "trades",
instId: instId,
}]
}
} else {
let symbol = exchange.GetCurrency().replace('_', '').toLowerCase()
msg = {
method: "SUBSCRIBE",
params: [symbol + "@aggTrade", symbol + "@depth20@100ms"],
id: "1",
}
}
ws.write(JSON.stringify(msg))
Log("subscribe", msg, "channel")
LogStatus("Ready")
}, onTick, Debug)
while (true) {
ctx.poll()
EventLoop(1000)
}
}
Esto funciona de la siguiente manera, también se puede suscribir varias variedades en la función de suscripción
A continuación se muestra el efecto de una estrategia de mercado común de OKX y de BIN en BIN con esta plantilla.
