Thank you Tomasz I used PREV and the function seems to work OK,
except the line drawn on the chart doesn't seem correct, guess I got
it wrong. I'm trying to duplicate Guppys CountBack function, has
anyone already done this? I would realy appreciate seeing how to do
it! The MetaStock code is public and is as follows"
HighDays := Input("Enter # days to cover last HIGH for CBL calc'n:",
3, 55, 13);
If(HIGH < HHV(HIGH, HighDays), {then ...} PREV, {previous CBLhi,
else...}
If(Ref(L,-2) < Ref(L,-1) AND Ref(L,-2) < L AND Ref(L,-1) < L,
{then ...} Ref(L,-2), {2nd day back low, else...}
If((Ref(L,-3)< Ref(L,-2) AND Ref(L,-3) < Ref(L,-1) AND Ref(L,-3) < L)
AND (Ref(L,-2)< L
OR Ref(L,-1) < L), {then ... } Ref(L,-3), {3rd day back low,
else...}
If((Ref(L,-4)< Ref(L,-3) AND Ref(L,-4) < Ref(L,-2) AND Ref(L,-4) < Ref
(L,-1) AND Ref(L,-4) < L) AND (Ref(L,-3)< L
OR Ref(L,-2) < L
OR Ref(L,-1) < L), {then... } Ref(L,-4), {4th day back low, else...}
If((Ref(L,-5)< Ref(L,-4) AND Ref(L,-5) < Ref(L,-3) AND Ref(L,-5) < Ref
(L,-2) AND Ref(L,-5) < Ref(L,-1) AND Ref(L,-5) < L) AND (Ref(L,-4)
<L
OR Ref(L,-3) < L
OR Ref(L,-2) < L
OR Ref(L,-1) < L), {then ...} Ref(L,-5), {5th day back low, else...}
PREV )))))
Hope someone can help, thank you.
