Pemakluman harga

Contoh

Objek API pemakluman harga mengembangkan fungsi pengundian harga dan boleh digunakan untuk melakukan perkara berikut:

  • Mencipta sistem pemberitahuan dagangan dan aplikasi
  • Mengkonfigurasi dagangan bersyarat dalam algoritma
  • Memantau sentimen pasaran
  • Meningkatkan strategi pengurusan risiko.

Laksanakan dagangan menggunakan pemakluman

Anda boleh mengekod algoritma untuk melaksanakan dagangan apabila pemakluman harga dicetuskan.

protected override void OnStart()
{
    PriceAlerts.Triggered += PriceAlerts_Triggered;
}

private void PriceAlerts_Triggered(PriceAlertTriggeredEventArgs obj)
{
    var symbol = obj.PriceAlert.Symbol;
    ExecuteMarketOrder(TradeType.Buy, symbol.Name, 10000);  
    Print($"Price alert triggered, trade executed for {symbol.Name}");
}

Urus dagangan secara dinamik

Anda boleh mengekod algoritma untuk mengubah suai tahap henti rugi dan ambilan untung bagi posisi terbuka secara dinamik apabila pemakluman dicetuskan. Dengan cara ini, tahap henti rugi dan ambilan untung dipindahkan atau dilaraskan apabila harga simbol menghampiri tahap utama, yang membolehkan dagangan berjalan lebih jauh mengikut keperluan.

    foreach (var position in positions)
    {
        position.ModifyStopLossPrice(obj.PriceAlert.Price - 50 * obj.PriceAlert.Symbol.PipSize);
    }
}
