/* Serge: This indicator includes 3 original BrainTrend2 indicators as I am 2 lazy to apply 
   them all one by one on a chart:
   BrainTrend2Stop, BrainTrend2StopLine, BrainTrend2Sig
   Note: BrainTrend2 indicator is not included as we use BrainTrend1 indicator for trend direction
   It has customisable external variables that can be played with during optimisation
   Also I renamed variables, simplified & logically re-arranged the codes of the original indicators 
   to make them more understandable (I mean for myself :-)
