===================
+-100 in 2 or 3 bars, then order in proper direction
small losslimit, large profitmade

==========
whatever works best

PAIRS
=====
EURUSD

ENTRY LONG
==========
CCI < -100 to CCI > +100

ENTRY SHORT
===========
CCI > +100 to CCI < -100

EXIT
====
ProfitMade (optimized by month)

MONEY MANAGEMENT
================
none

RISK MANAGEMENT
===============
