Sectors Relative Strength Normal Distribution

I wrote this indicator as an attempt to see the Relative Strengths of different sectors in the same scale, but there is also other ways to do that.

This indicator plots the normal distribution for the 10 sectors of the SPY for the last X bars of the selected resolution, based on the selected comparative security. It shows which sectors are outperforming and underperforming the SPY (or any other security) relatively to each other by the given deviation.
