Instrument – instrument name, relative to which the calculation is made
First EMA period – first exponential smoothing period
Second EMA period – second exponential smoothing period
Period – indicator calculation period
Overbought – overbought level
Oversold – oversold level
Calculation:
WV = 100.0 * (Value - Min) / (Max-Min)
where:
Value = MA1-MA2
MA1 - EMA(Price, First EMA period)
MA2 - EMA(Price, Second EMA period)
Max, Min - maximum and minimum 'Value' values in the Period range
Price = Close(Current Instrument) / Close(Instrument)
Keep in mind that the indicator needs to upload history data of a selected instrument during the first launch or when changing ‘Instrument’. If the re-drawing does not occur quickly or the indicator is displayed incorrectly, simply switch the chart timeframe to accelerate the process and obtain a correct display.
