//  Formula Name:    Relative Strength Multichart of up to 10 tickers
//  Author/Uploader: Frederick M Miller 
//  E-mail:          
//  Date/Time Added: 2004-02-09 23:46:38
//  Origin:          Modified Frederick Miller 1/9/04 Modified K Close 8/2/02 support code from Thomas Zmuck/Anthony Faragasso
//  Keywords:        
//  Level:           medium
//  Flags:           indicator
//  Formula URL:     http://www.amibroker.com/library/formula.php?id=335
//  Details URL:     http://www.amibroker.com/library/detail.php?id=335
//
//------------------------------------------------------------------------------
//
//  A modified indicator to function like the FastTrack total return charts
//  normalizing up to 10 tickers for relative strength comparison. This
//  indicator supports the date pole and date markers.
//
//  Tickers are loaded using Parameters or [CNTRL]R
//
//  Colors are selected for a black screen, but are easily modified in the
//  code.
//
//------------------------------------------------------------------------------
// Multi - Charts in the FastTrack Total Return Format
// Normalized to left edge with right axis indicating %return of screen
// Bracketed values indicate returns from left screen to pole OR
// between Date markers if in place
// Use <Cntr>R to set ticker symbols
// left click to set pole, double left click to set marker 
// Colors may be changed below:
