Historical data

Blackwood provides historical candles, which can be used for testing, and to initialize the indicators.

Work with historical candles

  1. In order to get historic candles, call BlackwoodTraderSubscribeCandles(CandleSeries, DateTimeOffset, DateTimeOffset) method:

    C#
    var tf = (TimeSpan)CandlesPeriods.SelectedItem;
    var series = new CandleSeries(typeof(TimeFrameCandle), SelectedSecurity, tf);
    Trader.SubscribeCandles(SelectedSecurity, DateTime.Now.Subtract(TimeSpan.FromTicks(tf.Ticks * 100)), DateTime.Now);
  2. Historical candles passed through the BlackwoodTraderNewCandles event:

    C#
    Trader.NewCandles += _securitiesWindow.AddHistoricalCandles;
  3. Appeared candles can be drawn through the graphical control:
