Main Category: Spreads / Overlays

Description:
Non-price study of $TICKI draws HLC information and colors the bar red as the $TICKI High or Low exceeds the upper or lower extreme parameters.

Formula Parameters:
nTickiHigh: Default is 24
nTickiLow: Default is -24
nNumBars: Default is 150

/***  Updated:  5/30/03

*Changed logic for creating HL bars from histograms to drawLineRelative()
    lines similar to TickExtremes.efs.

***/

/***  Updated:  4/30/03

*Changed color scheme to red(extreme breach)/blue(no breach).
*Logic for High/Low of bar improved.
*Fixed bug for Edit Studies change of nTickiHigh/nTickiLow.
