BCGControlBar Pro for MFC

Detailed Description

A Stochastic indicator is represented by two lines. The main line is called %K, the second - %D, which is a moving average (MA) of %K. The formula itself implements %K. To display %D just create CBCGPChartMAFormula with desired MA type using the output series of %K as an input series.

The following parameters should be defined for Stochastic:

  • Period of KSlowing of %K, which defines the internal smoothing of %K line.
  • %D - period of MA applied to %K and a type (simple, exponential, snooted, linear weighted) of MA.

The following example demonstrates how to set up a Stochastic Oscillator with periods 5, 3, 3 and display it on a custom axis (making up an indicator area):

CBCGPChartAxis* pAxisStochastic = (CBCGPChartAxisY*) pYAxis->Split(80, 3, NULL, FALSE);
pAxisStochastic->SetFixedDisplayRange(0, 100, 50);
CBCGPChartStockSeries* pStockSeries = new CBCGPChartStockSeries(pChart, CBCGPBaseChartStockSeries::SST_CANDLE);
CBCGPChartStochasticFormula stochastic(5, 3);
CBCGPChartSeries* pStochSeries = stochastic.Create(pChart, _T("Stochastic"), pStockSeries, pAxisStochastic);
CBCGPChartMAFormula signalStoch(CBCGPChartMAFormula::MA_SIMPLE, 3);
CBCGPChartSeries* pSignalStochSeries = signalStoch.Create(pChart, _T("Stochastic Signal"), pStochSeries, pAxisStochastic);

If you provide a main stock series as an input series, the formula implementation will automatically take high, low and close child series to compute the output series.
