Sample code

Realtime API Public Channels

using BitFlyerDotNet.LightningApi;

// Display realtime executions from WebSocket
using (var factory = new RealtimeSourceFactory())
using (var source = factory.GetExecutionSource(BfProductCode.FXBTCJPY))
{
    source.Subscribe(exec =>
    {
        Console.WriteLine("{0} {1} {2} {3} {4} {5}",
            exec.ExecutionId,
            exec.Side,
            exec.Price,
            exec.Size,
            exec.ExecutedTime.ToLocalTime(),
            exec.ChildOrderAcceptanceId);
    });
    Console.ReadLine();
}

Realtime API Private Channels

using BitFlyerDotNet.LightningApi;

// Input API key and secret
Console.Write("Key:"); var key = Console.ReadLine();
Console.Write("Secret:"); var secret = Console.ReadLine();

// Display child order event from WebSocket
using (var factory = new RealtimeSourceFactory(key, secret))
using (var source = factory.GetChildOrderEventsSource(BfProductCode.FXBTCJPY))
{
    source.Subscribe(e =>
    {
        Console.WriteLine($"{e.EventDate} {e.EventType}");
    });
    Console.ReadLine();
}

Public API

using BitFlyerDotNet.LightningApi;

// Get supported currency pairs and aliases
using (var client = new BitFlyerClient())
{
    var resp = client.GetMarkets();
    if (resp.IsError)
    {
        Console.WriteLine("Error occured:{0}", resp.ErrorMessage);
    }
    else
    {
        foreach (var market in resp.GetMessage())
        {
            Console.WriteLine("{0} {1}", market.ProductCode, market.Alias);
        }
    }
}

using BitFlyerDotNet.LightningApi;

// Buy order
Console.Write("Key:"); var key = Console.ReadLine();
Console.Write("Secret:"); var secret = Console.ReadLine();

using (var client = new BitFlyerClient(key, secret))
{
    Console.Write("Price:"); var price = decimal.Parse(Console.ReadLine());
    client.SendChildOrder(BfProductCode.FXBTCJPY, BfOrderType.Limit, BfTradeSide.Buy, price, 0.001);
}

Known issues

• 2020/07/27 GetParentOrders API is too slow or sometimes returns "Internal Server Error" if target period contains old order. Probably old parent orders are stored another slow database.
