CBCGPChartAdvancedFormula

Detailed Description

The CBCGPChartAdvancedFormula class is an abstract base class for various formulas that can be applied to a chart series and generate a new series whose data points are computed using a custom algorithm.

Currently this class establishes an infrastructure for building financial indicators, but can be used to generate data points for any input series.

You can derive a custom class from CBCGPChartAdvancedFormula and override CBCGPChartAdvancedFormula::CalculateDataPoint method to update a data point at the specified index. This method will be called when you attach an input series or change any input parameters. If your input series is updated in the real time, you need to call UpdateLastDataPoints to sync the output series with the input. You can use CBCGPChartSeries::GetDataBuffer to store any data for intermediate calculations.

You must also override CBCGPChartAdvancedFormula::CopyFrom if your custom class has to store any private data.

The Create method should be called (and can be overridden in a derived class) to display the formula on chart.
