/*
History:

Version 1.0 
- intial expert coded by Shahin Monsef

Version 1.1 / Aug 27, 2005: mods by Shimodax
- option for min channel width
- now checks laguerre for level crossing 
- option to use or ignore asctrend from decision
- added trail stop trigger (profit from which trailstop gets activated) 

Version 1.2 / Aug 28, 2005: mods by Shimodax
- handle laguerre signal correctly (stays valid for x (Input) minutes)
- don't reenter trades on the same bar
