GetBiasStudy

GetBiasStudy() Advanced GET Study Functions

Creates object, which allows to get signals of indicator Advanced GET Bias Reversal in EFS scripts. The Bias Reversal indicates a potential change in trend (a reversal of a bias) point.

Syntax

GetBiasStudy( bFilter , Mode )

Parameters

Parameter:

Description:

Default:

bFilter	Boolean. When True, the Filter removes any Bias Reversal signals that have been marked as false signals. When False, false Bias Reversal signals will be returned.	n/a
Mode	Allows to choose between Normal and Tight sensitivity level for the Bias Reversal calculation. To choose sensitivity level use constants GetBiasStudy.NORMAL or GetBiasStudy.TIGHT.	n/a

Member(s)

Syntax:

Returned value:

GetBiasStudy.BIAS

Returns series, which contains the following values: 1 - true signal for reverse pivot from bullish to bearish trend, 2 - false signal for reverse pivot from bullish to bearish trend, 254 - false signal for reverse pivot from bearish to bullish trend, 255 - true signal for reverse pivot from bearish to bullish trend

Notes

Only available in versions 7.9 or later.

 

Code Example

Creation Object Example:

var xBias = null;
function main() {
  if (xBias == null) xBias = new GetBiasStudy(true, GetBiasStudy.NORMAL);
  var vBias = xBias.getValue(GetBiasStudy.BIAS);
  return vBias;
}
