Price returns the average of the high and low values for the bar.  Ehlers uses this value in most of his indicators when he is referring to a price data stream. (Exceptions are noted at the end of this topic.) The indicators in the Cybernetic Analysis add-on default with a value of Close for the PriceIn parameter.  The user needs to change the parameter value of Close to the Price indicator in order to match the results described by Ehlers.

Operand #1 = High

Operand #2 = Low

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
