Doesn't seem to hit the mark Geoff even though the
condition has changed to false
check it out agains AAT on the asx
you will see what i mean condition is met on the
1.02,2001 but price fall below the mov's and the signal it still true
...
lol i think i have it right..
test= cross(ma(close,10),ema(close,20));//shows
the cross of mov'sbuycross=hhv( test, 10 );//displays a buy for 10 periods
after test buy= buycross;sell = 0;

David,
I think Steve's second email is a
good solution using Cross in conjunction with HHV - it allows you to
look backward in time.
I'll continue to play around as this scan it
something I will use.
Tomasz,
Can you please confirm that the Hold condition
sets the array to 1 forward in time the specified number of slots
in the hold result array from the first position where it was set to1
(ie true) ?
Thanks,
Geoff

ok I'm concerned that if the condition changes ami will
still hold it trueeven though it is now false using the hold()."This
true result is held true over the number of periods specified even ifa
"false" result is generated. "I don't wish to extend the
condition forcing a false signal.What I wanted was if condition x is
meet then as long as its true look forthe next condition .I guess
you can see the intent in the bow tie formula.has the ma10,ma20
,ma30 crossed in the last xn daysif yeshas the pull back
occurredif yeshas the higher high occurredif all 3 conditions
are true then signal a buyGeoff's multi condition does itbut
was looking for a cleaned way toexpress it .Maybe i just have to
nest a bunch of conditions and if there true nestanother.DOES
THIS MAKE sense to anyone or is my logic out of sync/* Bow Tie

average sometime in the last xn days - Add more conditions for moredays
