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

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

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
