Average True Range Stop and Reverse(ATRSAR)

This indicator is base on Stop and Reverse strategy that can be used as a reference for whether or not the trend is reversed.
This indicator is mainly for the situation that the cryptocurrency usually has a triangular convergence before the trend, and the ATR will fall to a low value. After the break out, a large-scale movement will occur and the ATR will rise rapidly.
In response to this situation, this indicator takes the maximum/minimum value of the past period as the initial value of Stop and Reverse, and uses the rate of change of ATR as the parameter of the approximation.
It is theoretically most of the trending markets can use this indicator as a reference, but must find the parameters that suit the market rhythm.
This indicator mainly refers to the ATRTSS indicator and the MASAR indicator by cI8DH.
