WMA Bands

In this chart we can see an adaptation I made of an indicator a certain fellow named nanningbob uses in one of his trading systems.
It's a great thing to have, since Forex pairs are mostly ranging markets. It captures price movement very well, and gives realistic take profit levels, without having to risk major drawdown if used wisely.

Hope you like it and find it useful.

*Props to ucsgears for the original code I modified.
