//The basic idea of the strategy is to select the best set of MAs, types, lenghts and offsets, which draws red trend bands for downtrend (and green for uptrend).
//Strategy executes by selected risk level either when there is MA crossover with price (MA1 Offset1 on Highest risk level, MA2 on Low risk level) or three bands with the same color on at the same time (on Lowest risk level).
//Strategy plots user selectable Moving Average lines and a colored trend band between the MA lines. The trend bands can be turned off individually if required.
//The Offset option shifts the selected MA with the set number of steps to the right. That is where the Magic happens and the Dragon roars!
