<br><font size=2 face="sans-serif">Ah! So you meant how to auto-find the
H and L locations, not just draw the symbols. You can use a combination
of the maxloc and max, or minloc and min, functions. I would check out
the clhilo udf that Matias suggested (thanks for mentioning, Matias). I
have not used that one personally.
