Most of the indicators in this add-on include a parameter called "PriceIn".  The default value in the indicators for PriceIn is the Close.  This is NOT the value used in Ehlers’ book and you must substitute the Price indicator (included with this add-on) to duplicate Ehlers’ indicators.  Price is simply an indicator that averages the High and Low values in the bar.

As always, there are exceptions to the rule:

StochasticRSI uses Close rather than the Price indicator

Laguerre RSI indicator uses Close value rather than the Price indicator
