//  Keywords:        Performance View
//  Level:           advanced

//------------------------------------------------------------------------------
//
//  This formula is for indicator builder and shows you the performance from 4
//  user-defined tickers or indices and the current ticker.
//
//  0% is always on the first visible bar over the zoomed area. You can also
//  scroll the chart, 0% is always on the left.
//
//  Activate Percent in Indicator builder and select Level 0
//
//  Note: It requires the gaussian DLL for smoothing, but you can also change
//  in every line: gauss2ord to MA or any other moving, but i think gauss2ord
//  smoothing much better than ma or ema or anything else.
//
//  The gauss2ord plugin is available here:
//
//  http://groups.yahoo.com/group/amibroker/files/PLUGIN%20DLL/Gaussian.dll
//
//  Save it in amibroker/plugin folder and restart AB or go Plugins and Load
//  again.
