The indicator plots the smoothed value of the following experession:
Out[i]=MathLog(Close[i]/Close[i+ExtPeriodAcc]),
where ExtPeriodAcc is the accelerator period, defined by “Acc period” input parameter.
The smoothing is carried out by four-pass EMA with period, specified in the “MA period” input parameter.
Input parameters:
- Acc period – accelerator period;
- MA period – averaging period;
- N History – number of bars to plot.
