Pattern detection

Pattern detection is removed from version 3.0, if you need pattern detection use v2.0

All indicators will be available in window object. So you can just use

sma({period : 5, values : [1,2,3,4,5,6,7,8,9], reversedInput : true});

or

SMA.calculate({period : 5, values : [1,2,3,4,5,6,7,8,9]});
