Tirone Levels is a group of horizontal trend lines that are meant to identify support and resistance levels.

Prices are usually expected to have support and resistance near Tirone Levels.

The TA TironeLevelfunction 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 zero (0).

Class: LineStudy


Public function TironeLevel(ByRef Data As Database, ByRef OHLCV As , ByVal StartPeriod As Integer, ByVal EndPeriod As Integer) As RecordSet



Return Type Returns object of type RecordSet
Default Field Name(s) TironeTop, TironeMedian, TironeBottom
