BCGControlBar Pro for MFC: CBCGPChartMACDFormula

Detailed Description

The formula is displayed as a histogram series and represents difference between slow and fast EMA. To show signal line you need to create an MA formula for MACD series.

The following example illustrates how to create MACD formula applied to close values of stock series with signal line:

Copy

// MACD
CBCGPChartMACDFormula macd(12, 26);
CBCGPChartSeries* pMACDSeries = macd.Create(pChart, _T("MACD"), pCloseSeries, pAxisMACD);
pMACDSeries->m_bIncludeSeriesToLegend = FALSE;
// MACD Signal
CBCGPChartMAFormula signalMACD(CBCGPChartMAFormula::MA_SIMPLE, 9);
CBCGPChartSeries* pSignalMACDSeries = signalMACD.Create(pChart, _T("Signal MACD"), pMACDSeries, pAxisMACD);
pSignalMACDSeries->m_bIncludeSeriesToLegend = FALSE;
// where pAxisMACD is Y axis of MACD series.
