this is a linear regression type of trend line. so we have two linear regressions (the one as lines is current with value in red)
the dashed is the one based on starting point in the past (yellow value)
by this way we can make a trend line type that based on linear regression and not in the regular way based on high and low
crossing any of the backward linear regression or trend line regression show a signal . cross up is green triangle. cross down is red triangle.
so in basic it a linear trend line type of indicator
