is this similar to what you are asking. in the z= formula for
every true it adds 1 to the projection band so if (IIf(L<Ref(L,-
1),1,0) +IIf(L<Ref(L,-2),1,0) these 2 days were true it would change
the periods in the lowslope formula to 2.
z=IIf(L<Ref(L,-1),1,0) +IIf(L<Ref(L,-2),1,0)+IIf(L<Ref(L,-3),1,0)+IIf
(L<Ref(L,-4),1,0)+IIf(L<Ref(L,-5),1,0)+IIf(L<Ref(L,-6),1,0)+IIf(L<Ref
(L,-7),1,0)+IIf(L<Ref(L,-7),1,0)+IIf(L<Ref(L,-8),1,0)+IIf(L<Ref(L,-
9),1,0)+IIf(L<Ref(L,-10),1,0)+IIf(L<Ref(L,-11),1,0)+IIf(L<Ref(L,-
12),1,0)+IIf(L<Ref(L,-13),1,0);
Aa=((z * (Sum( Cum(1) * Low, z))) - (Sum( Cum(1), z) * ( Sum(Low,
z))))/
((z * Sum(( Cum(1)^ 2), z)) - ( Sum(Cum(1),z)^2 ));
Lowslope=Aa;
Graph0=Min(Low,
Min( Ref(Low,-1) + 1 * (lowslope ),
Min( Ref(Low,-2) + 2 * (lowslope ),
Min( Ref(Low,-3) + 3 * (lowslope ),
Min( Ref(Low,-4) + 4 * (lowslope ),
Min( Ref(Low,-5) + 5 * (lowslope ),
Min( Ref(Low,-6) + 6 * (lowslope ),
Min( Ref(Low,-7) + 7 * (lowslope ),
Min( Ref(Low,-8) + 8 * (lowslope ),
Min( Ref(Low,-9) + 9 * (lowslope ),
Min( Ref(Low,-10) + 10 * (lowslope ),
Min( Ref(Low,-11) + 11 * (lowslope ),
Min( Ref(Low,-12) + 12 * (lowslope ),
Ref(Low,-13) + 13 * (lowslope ))))))))))))));
below is the 14 period projection bands which when compared to
your original formula looks similar.
lowslope=((14 * (Sum( Cum(1) * Low, 14))) - (Sum( Cum(1), 14) * ( Sum
(Low, 14))))/
((14 * Sum(( Cum(1)^ 2), 14)) - ( Sum(Cum(1),14)^2 ));
Graph0=Min(Low,
Min( Ref(Low,-1) + 1 * (lowslope ),
Min( Ref(Low,-2) + 2 * (lowslope ),
Min( Ref(Low,-3) + 3 * (lowslope ),
Min( Ref(Low,-4) + 4 * (lowslope ),
Min( Ref(Low,-5) + 5 * (lowslope ),
Min( Ref(Low,-6) + 6 * (lowslope ),
Min( Ref(Low,-7) + 7 * (lowslope ),
Min( Ref(Low,-8) + 8 * (lowslope ),
Min( Ref(Low,-9) + 9 * (lowslope ),
Min( Ref(Low,-10) + 10 * (lowslope ),
Min( Ref(Low,-11) + 11 * (lowslope ),
Min( Ref(Low,-12) + 12 * (lowslope ),
Ref(Low,-13) + 13 * (lowslope ))))))))))))));
cheers: nirvana.
