The DeMarker consists of one curve with a period of 14. This value can be changed.
If you reduce the period, the number of signals will be more, but many of them will be false. If you increase the period, the signals will be less, but they will be more accurate.
The RSI line is moving within the limits of 0 and 100. At the same time, it periodically crosses the levels: overbought level 0.7 and oversold level 0.3. These are the key levels, as crossing the DeMarker line with them gives signals to enter the market.
Beginners are recommended to use the standard oscillator settings: period 14, overbought level 0.7 and oversold level 0.3. These values are considered optimal for the quality and quantity of signals.
