All Implemented Interfaces:

Resettable, RTIndicator

public class ChandeForecastOscillatorRTIndicator
extends AbstractRTIndicator

Chande Forecast Oscillator (CFO) with O(1) per-tick computation.

  CFO = 100 * (close - LSMA(close, period)) / close

Measures the percentage deviation of price from its linear regression forecast. Positive values indicate price is above the trend, negative values below. Typically oscillates in the -5 to +5 range.

getPeriods

public int getPeriods()

getLsmaValue

public double getLsmaValue()

isReady

public boolean isReady()

Description copied from interface: RTIndicator

Returns whether this indicator has received enough data to produce meaningful values.

During the warmup period, RTIndicator.getValue() may return 0 or a partial estimate that should not be used for trading decisions. Once this method returns true, the indicator's output is statistically valid.

The default implementation returns true for backward compatibility. Indicators with warmup requirements should override this method.

For composite indicators (e.g. Bollinger Bands, MACD), readiness is determined by the slowest internal component.

Returns:

true if the indicator has completed its warmup period
