Effort Result oscillator displays correlation of the price change speed to the maximum volume for the specified time interval.

It has one configurable parameter:

  • Period - calculation period

Calculation:

ER = ROC / MaxVol

where:

ROC = 100.0 * (Price / Price[Period]-1)
Price = SMA(Close, Period)
MaxVol - maximum volume in the Period range

The indicator has a peculiarity: sharp spikes of the oscillator values often forecast a price reversal towards the oscillator reversal
