Syntax
Public function QuadrantLines(ByRef Data As Database, ByRef OHLCV As RecordSet, ByVal StartPeriod As Integer, ByVal EndPeriod As Integer) As RecordSet
Overview
Quadrant Lines measure the highest highs and lowest lows over a specified period of time and divided these values into quadrants.
Interpretation
Quadrant Lines are most often used as a visual aid for price movement inspection.
Note
The TA QuadrantLines function is different from other TA functions.
The function returns a Recordset object, however, the returned values are present only between the start and end periods of the calculation as specified in the function arguments. All other values in the returned Recordset object will equal to zero (0).
Class: LineStudy
Parameters
Return Type | Returns object of type Recordset |
Default Field Name(s) | QuadrantLines1, QuadrantLines2, QuadrantLines3, QuadrantLines4 |
