Al, probably because that
is the way you learn it. In this case where the answer I want is just 0 or 1
then yes you could use the straight logic. Just never thought of doing it that
way. Thanks for the help.

Graham:
I've noticed you and lots of other folks on this board seemingly
unnecessarily use the iif statement a lot, as in your Rise and Fall code lines
below. Yet, isn't it just as correct and less code (i.e., more efficient) to
simply write:
Rise = H>Ref(H,-1) AND L>Ref(L,-1);
Just curious why people use iif so much. Thanks.

I recently posted an
indicator which could be roughly what you are looking for, at least for the
trend identifiaction. I will post another version of what I am doing, and
see if it can be modified to get what you want
Can't remember which
one I posted, but here is latest of this particular strain of my

davisSubject: [amibroker] lower highs, lower
lows
A lot of traders are expecting the
markets to turn down any day now, so I made an CRUDE AA scan
that is designed to find stocks that have been
trending up for awhile, but which have recently
started trending down. Although I have
posted the code below, I am not looking for
suggestions for improving this CRUDE scan. I am still
struggling with AFL, so I am not yet able to create the AA scan that will
look for exactly the conditions that I want to scan for.
I really want a scan that will find those symbols that
meet the Weinstein definition of the ending of an uptrend and the
entering of a downtrend. I am aware that DT is a little
suspicious of Weinstein because he wears a ring on his
pinkie. It bothers me a little also, but at least he
doesn't wear a ring in his nose, at least not yet, as far as I
know . I am thinking that a lot of Amibroker users would like
to have a scan which will find the conditions which are necessary
for finding a Weinstein change from uptrend to downtrend. My
understanding of Weinstein trends is that after a series of higher highs
and higher lows, we suddenly see a lower low, then we need to be
worried. After the appearance of this first lower low, we need to
keep watching till the next high occurs. If this next high is lower
than the previous high, then we are officially in a Weinstein
downtrend. The attached chart that resulted from my CRUDE
coding is approximately the kind of results that will result from a
precise coding of the Weinstein change of trend definition. Since an
AA scan for these Weinstein change of trend conditions will be
useful to a lot of Amibroker users, I would greatly appreciate it if some
experienced Amibroker coders would post the code for that looks for these
precise condtions. Ron D
