Fungsi pelaksanaan:
- Aliran awam, trades dan sintesis mendalam
- Pendaftaran aliran peribadi, memelihara surat perintah dan kedudukan tempatan, dan maklumat baki
- Mengekalkan status membatalkan pesanan yang terlewat, menyokong amendOrders OKX untuk mengubah pesanan
- Menyokong pelbagai jenis, memudahkan strategi frekuensi tinggi untuk beroperasi di beberapa pasaran pada masa yang sama dengan kelewatan minimum
- Tambah fungsi EventLoop (yang memerlukan sokongan hos terkini), fungsi ini boleh digunakan dalam kes sambungan pelbagai websocket, menunggu data websocket arbitrer kembali, mengelakkan tinjauan
- Sokongan OKX dan Binance Futures dan Binance Cash and Cash Leverage Trading, OKX Cash belum lagi disokong, yang berminat boleh menukarnya sendiri
- OKX streaming peribadi langganan memerlukan kunci dan kata laluan telah dibuat sebagai parameter yang ditulis dalam templat
- Menguruskan fungsi rangkaian asas seperti sambungan semula secara automatik
- Kembali pada peristiwa yang menyokong penghapusan bayaran balik untuk pesanan aliran peribadi
- Menggabungkan logik pesanan kedua-dua bursa, lihat sumber templat atau contoh
- Websocket interface yang menyokong langganan ke beberapa bursa
- Pengubahsuaian dan penghapusan pesanan boleh dibuat secara besar-besaran sebagai tugas yang dikembalikan, yang akan memproses tugas transaksi secara automatik
Pada masa yang sama, ia mungkin berlaku bahawa apabila anda membuat pesanan pada frekuensi tinggi, ia mungkin tidak akan kembali pada masa yang sesuai (dengan saluran peribadi), tetapi keadaan mungkin telah berubah, dan anda perlu mengekalkan keadaan pesanan secara tempatan. Templat ini secara automatik akan mengenal pasti sama ada OKX atau Binance, berikut adalah contoh mudah, dan kami sangat mengesyorkan membaca kod sumber untuk menyesuaikan fungsi anda dengan lebih mendalam
Berikut adalah contoh yang mudah.
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 {

}],
cancelOrders: [{

}]
}
}
}
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)
}
}
Ia berfungsi seperti berikut, anda juga boleh membuat langganan kepada pelbagai jenis dalam fungsi langganan:
