Relative Strength Index Symmetric
In indicators the positive scale often unreasonably is accepted though in fact they are the symmetric.
Such property has also standard RSI. Besides, operation in Close price not always adequately displays actual historical levels of the indicator.
This indicator is designed to eliminate these defects.
However by search of a divergence it is necessary to consider what in the upper part of the indicator can be looked for only on peaks, and in the lower part of the indicator - on troughs.
RSI Period - the indicator period.
Accuracy - the accuracy of computation, signs after a comma (from 1 and more).
But within limits, to the compiler to spit on your desires.
