Calculates standard error and constructs Confidence Intervals for mean

Mobius

V01.01.01.2018

{Simple Confidence system. Trade is taken when close crosses the mean and added to when price is outside the confidence bands and trade is exited once close crosses into the bands.} Really know more of the indicator except that one can changed=number of days. The red labels indicate the Laguerre indicator a part of the Confidence Mean Indicator. and definitely dont understand the thumbs down lol.
