AGet.biasReversal() Advanced GET Studies
Returns the series or values of the GET Bias Reversal study.
The Bias Reversal indicates a potential change in trend (a reversal of a bias) point.
Syntax
AGet.biasReversal( Filter , Sensitivity [, sym() | inv() ][, BarIndex ] )
Parameters
| Parameter: | Description: | Default: |
| Filter | A boolean value. 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 |
| Sensitivity | Allows to choose between Normal and Tight sensitivity level for the Bias Reversal calculation. To choose sensitivity level use constants: BIASREVERSAL_NORMAL = 0 BIASREVERSAL_TIGHT = 1 |
n/a |
| sym() | inv() | [Optional] Function of sym() or inv() to determine symbol/interval source for the study. | Base sym/int |
| BarIndex | [Optional] Bar index of series to retrieve. | n/a |
Return Value(s)
Returns a Series Object when nBarIndex is not specified. It consists of the set of constants shown below.
Returns a single value when nBarIndex is specified from the set of constants shown below.
A set of constants:
NONE = 0
TRUE_BULLISH = 1
TRUE_BEARISH = -1
FALSE_BULLISH = 2
FALSE_BEARISH = -2
Notes
Only available in versions 11.8 or later.
Code Example
Creating and Using Series Example:
var bInit = false;
var xSer = null;
setPriceStudy(true);
function main() {
if (bInit == false) {
xSer = AGet.biasReversal(true, BIASREVERSAL_NORMAL);
bInit = true;
}
if (isLastBarOnChart()) {
clearShape();
recalculate(function () {
var nSer = xSer.getValue(0);
if (nSer == null || nSer == NONE) return;
var location = null;
var color = null;
var shape = null;
if (nSer > 0) {
location = TopRow1;
color = Color.red;
shape = Shape.DOWNTRIANGLE;
} else {
location = BottomRow1;
color = Color.blue;
shape = Shape.UPTRIANGLE;
}
drawShape(shape, location, color, "Bias" + getCurrentBarCount());
});
}
}
