*Inner lines are calculated with 2 Standard Deviation ( as classical ) and outer ones are with 3 Standard Deviation.
*3 SD calculation is important because, it is useful to investigate further the .
*Classical Basis is included in calculations to obtain the bands, but the basis isn't plotted (SMA20).
*For Basis, a-13 bar line is added which tells "BUY" when GREEN, and which tells "SELL" when RED.
*Generally, this code is good to further investigate the especially by the help of 3SD lines. It is particularly important for crypto currencies which are generally highly volatile. On the other hand, the basis will tell BUY-SELL points and BUY-SELL points can be confirmed further, by investigating classical rules and anticipate about the .
