The standard deviation measure the dispersion of a data set, in short this metric will tell you if your data is on average closer or farther away from the mean. Its one of the most important tools in statistics and living without it is pretty much impossible, without it you can forget about Bollinger-bands, CCI, and even the LSMA (ouch this...
This indicator shows price in relation to the standard deviations in a normalised way.
It can be seen as a kind of Bollinger Bands, where the bands stay the same size apart and price amplitude is modified between them,
or as a 'normalised' version of my BBC indicator.
Contrary to the popular use where price is seen as BOUNCING AGAINST the different deviations...
