The \"Set RSI Smoothing?\" option enables cleaning up some of the RSI noise before ARSI is calculated. It is recommended to smooth RSI out with an EMA 3-7. This allows for less volatility and more consistent movements.<p>To use traditional ARSI without any enhancements, turn off both smoothing options.<p>Observations: When there's a strong reversal, ARSI will go flat and then bend to follow the price. On weaker events, ARSI will go flat while price bounces around above or below and then returns to the ARSI line. Check indicators and wave counts to verify final motion.<p>To visualize what the scaling factor is doing, a separate RSI graph can be added with the selected smoothing values. When RSI is close to 50, the ARSI line will go flat and move less. Further away from 50 will increase the line movement.";
