//    The "Sample Breakout Robot" will check the difference in pips between the Upper Bollinger Band and the Lower Bollinger Band 
//    and compare it against the "Band Height" parameter specified by the user.  If the height  is lower than the number of pips 
//    specified, the market is considered to be consolidating, and the first candlestick to cross the upper or lower band will 
//    generate a buy or sell signal. The user can specify the number of periods that the market should be consolidating in the 
//    "Consolidation Periods" parameter. The position is closed by a Stop Loss or Take Profit.
