Parabolic SAR has two main settings that affect its sensitivity and accuracy: the step and the maximum. The step is the amount by which the dots move closer or further away from the price with each new period. The higher the step, the more responsive the indicator is to price changes, but also the more prone it is to false signals. The lower the step, the less responsive the indicator is to price changes, but also the more reliable it is in identifying trends. The default value for the step is 0.02, but you can experiment with different values depending on your trading style and time frame. The maximum is the limit to which the dots can move away from the price. The higher the maximum, the more the indicator can accommodate strong and volatile trends, but also the more risk you take in terms of stop-loss distance. The lower the maximum, the less the indicator can accommodate strong and volatile trends, but also the less risk you take in terms of stop-loss distance. The default value for the maximum is 0.2, but you can also adjust it according to your risk tolerance and market conditions.
