//"------Step Setting Definition------"
//"A higher step moves SAR closer to the price action, which makes a reversal more likely."
//"The indicator will reverse too often if the step is set too high."

//"------Maximum Step Definition-----")
//"The sensitivity of the indicator can also be adjusted using the Maximum Step."
//"While the Maximum Step can influence sensitivity, the Step carries more weight"
//"because it sets the incremental rate-of-increase as the trend develops"
