I don't see how that helps. Let me write 2 versions of the indicator
for you to see. A 3 period and 5 period.
2 period
Min(L, Min(Ref(L,-1) +1* LinRegSlope(L, 3),
Min(Ref(L,-2) +2* LinRegSlope(L, 3)));
5 period
Min(L, Min(Ref(L,-1) +1* LinRegSlope(L, 5),
Min(Ref(L,-2) +2* LinRegSlope(L, 5),
Min(Ref(L,-3) +3* LinRegSlope(L, 5),
Min(Ref(L,-4) +4* LinRegSlope(L, 5)))));
You see how the number of lines change with different parameters.
