The SVS Oscillator is a custom technical indicator developed by Igor Somov and published on the MQL5 forum in 2014. It evaluates Trend Strength by comparing the current price with the previous two extreme values (highest high and lowest low).
The indicator helps traders determine whether price is closer to the prior high or the prior low — giving insight into momentum and potential reversals.
SVS Oscillator Formula
SVS Oscillator=(PreviousHigherHigh–CurrentPrice)–(PreviousLowerLow–CurrentPrice)\textbf{SVS Oscillator} = (Previous Higher High – Current Price) – (Previous Lower Low – Current Price)SVS Oscillator=(PreviousHigherHigh–CurrentPrice)–(PreviousLowerLow–CurrentPrice)
This calculation determines the price’s relative position between recent extremes.
