Getting started

The SampleBitStamp application shows an example of working with the BitStampTrader as shown in the figure below. The example source code is in the Samples/BitStamp folder of the installation package.

Bit Stamp Sample
  1. First, you need to create an instance of the BitStampTrader:

    C#
    Trader = new BitStampTrader() { LogLevel = LogLevels.Debug };
    .....
    Trader.ClientId = ClientId.Text.To<int>();
    Trader.Key = Key.Text;
    Trader.Secret = Secret.Password;
  2. Next, you should subscribe on required IConnector events:

    C#
    // subscribe on connection successfully event
    Trader.Connected += () =>
    {
        // set flag (connection is established)
        _isConnected = true;
    
        // update gui labes
        this.GuiAsync(() => ChangeConnectStatus(true));
    };
    Trader.Disconnected += () => this.GuiAsync(() => ChangeConnectStatus(false));
    
    // subscribe on connection error event
    Trader.ConnectionError += error => this.GuiAsync(() =>
    {
        // update gui labes
        ChangeConnectStatus(false);
    
        MessageBox.Show(this, error.ToString(), LocalizedStrings.Str2959);
    });
    
    // subscribe on error event
    Trader.Error += error =>
        this.GuiAsync(() => MessageBox.Show(this, error.ToString(), LocalizedStrings.Str2955));
    
    // subscribe on error of market data subscription event
    Trader.MarketDataSubscriptionFailed += (security, msg, error) =>
        this.GuiAsync(() => MessageBox.Show(this, error.ToString(), LocalizedStrings.Str2956Params.Put(msg.DataType, security)));
    
    Trader.NewSecurity += security => _securitiesWindow.SecurityPicker.Securities.Add(security);
    Trader.NewMyTrade += trade => _myTradesWindow.TradeGrid.Trades.Add(trade);
    Trader.NewTrade += trade => _tradesWindow.TradeGrid.Trades.Add(trade);
    Trader.NewOrder += order => _ordersWindow.OrderGrid.Orders.Add(order);
    
    Trader.NewPortfolio += portfolio =>
    {
        // subscribe on portfolio updates
        Trader.RegisterPortfolio(portfolio);
    
        _portfoliosWindow.PortfolioGrid.Portfolios.Add(portfolio);
    };
    Trader.NewPosition += position => _portfoliosWindow.PortfolioGrid.Positions.Add(position);
    
    // subscribe on error of order registration event
    Trader.OrderRegisterFailed += _ordersWindow.OrderGrid.AddRegistrationFail;
    // subscribe on error of order cancelling event
    Trader.OrderCancelFailed += OrderFailed;
    
    Trader.MassOrderCancelFailed += (transId, error) =>
        this.GuiAsync(() => MessageBox.Show(this, error.ToString(), LocalizedStrings.Str716));
  3. Finally, you need to connect to BitStamp server:

    C#
    Trader.Connect();
  4. Once connected, you can expect to trigger events:

  5. Instruments search (in more detail):

    Btce Securities
  6. For updates on the selected instrument and ticks you need to use the RegisterSecurity(Security) and RegisterTrades(Security) methods, respectively:

    C#
    private void QuotesClick(object sender, RoutedEventArgs e)
    {
        var trader = MainWindow.Instance.Trader;
    
        foreach (var security in SecurityPicker.SelectedSecurities)
        {
            if (trader.RegisteredSecurities.Contains(security))
            {
                trader.UnRegisterSecurity(security);
                trader.UnRegisterTrades(security);
            }
            else
            {
                trader.RegisterSecurity(security);
                trader.RegisterTrades(security);
            }
        }
    }
  7. To request updates on the order books you need to use the RegisterMarketDepth(Security) method:

    C#
    private void DepthClick(object sender, RoutedEventArgs e)
    {
        var trader = MainWindow.Instance.Trader;
    
        foreach (var security in SecurityPicker.SelectedSecurities)
        {
            var window = _quotesWindows.SafeAdd(security, key =>
            {
                // create order book window
                var wnd = new QuotesWindow
                {
                    Title = security.Id + " " + LocalizedStrings.MarketDepth
                };
                wnd.MakeHideable();
                return wnd;
            });
    
            if (window.Visibility == Visibility.Visible)
            {
                // unsubscribe from order book flow
                trader.UnRegisterMarketDepth(security);
    
                window.Hide();
            }
            else
            {
                // subscribe on order book flow
                trader.RegisterMarketDepth(security);
    
                window.Show();
            }
    
            if (!_initialized)
            {
                TraderOnMarketDepthChanged(trader.GetMarketDepth(security));
                trader.MarketDepthChanged += TraderOnMarketDepthChanged;
                _initialized = true;
            }
        }
    }
  8. For orders registration the New Order button used. The RegisterOrder(Order) method sends an order to the server:

    C#
    private void NewOrderClick(object sender, RoutedEventArgs e)
    {
        var newOrder = new OrderWindow
        {
            Order = new Order { Security = SecurityPicker.SelectedSecurity },
            SecurityProvider = MainWindow.Instance.Trader,
            MarketDataProvider = MainWindow.Instance.Trader,
            Portfolios = new PortfolioDataSource(MainWindow.Instance.Trader),
        };
    
        if (newOrder.ShowModal(this))
            MainWindow.Instance.Trader.RegisterOrder(newOrder.Order);
    }
