////////////Entry conditions and Concept/////////////////////
////////////Long Only System. T1 is measuring the distance between MACD EMA's. This is Multiplied
////////////by the sensitivity so that it can be compared to the difference between BollingerBand. 
/////////////{this could have been a ratio maybe i will work with that in a different script.} 
/////////////I found that 135-175 sensitivy allows for values to be compared on most charts.....
////////////If the (difference between the EMA)*(Sensitivity) is greater than (BB upper line- BB lower line)
////////////it is considered an explosion in either the downside or the upside.The indicator will print
///////////a bar higher than the trigger line either green or red (up or down respectively)//////////////////
