RE: Short Term High's/Low's

["David DeFina" <ddefina@xxxxxxxxxxxx>]

Using the HHV function you could code hhv(h,7) which would give you the
highest high for the last 7 days, including today, or ref(hhv(h,7),-1) for
the highest high excluding today.  And likewise the LLV function for lowest
low.  I don't know if this is what you're trying to accomplish, but this is
a good formula for identifying support/resistance points and for determining
stop placement.

Subject: Short Term High's/Low's

Hi,

Does anybody have any suggestions as to how I might code an expert to
identify short term high's and low's.
This is using the simple premise that inside days are ignored.  i.e.
previous non-inside day H is lower than current H which is higher than the
next non-inside day H (for High's - reverse for Lows).

At a guess, I need to use PREV to count the number of past consecutive
inside() days to get to the previous valid bar.  Not sure how to identify
the next valid bar or how to hang the lot together.

Perhaps I'm completely wrong in my approach and there is a simple route.

Thanks,
Sean
