In the LiteFinance terminal, you need to set three parameters: smoothing, the EMA period and the accuracy of the ADX value to the eighth digit. In the settings tab "Style" you can choose the color and thickness of the line. There is no smoothing option in MT4, but you can select the "Apply to" price type, which will be used in the indicator formula - open or close prices, period high or low prices, average price or weighted. Also in MT4, you can set horizontal levels that allow you to visually determine the central range of movement of the oscillator, overbought and oversold zones.
