    	Title:	Very Simple ADX DI+ DI- Crossing algorithm
    	
    	Author:	Johannes Ferner, johannes@ferner.me
    	Date: 	Sat 4. Feb. 2017
    	------------------------------------------------------------------------
    	Description:
    	
    	The Idea is to trade the crossings of DI+ and DI- through a ADX minimum level
    	Actions are only taken if the current ADX is above a certain minimum level
    	
    	Draft:
    	- Only open new Positions if ADX Value > 20 (_minADXlevel)
    	- Open Sell Position if DI- crossed through _minADXlevel and DI+ < _minADXlevel
    	- Open Buy Position if DI+ crossed through _minADXlevel and DI- < _minADXlevel
    	
    	Next Steps:
    	- Initial StopLoss
    	- Trailing StopLoss based on some ATR Magic
