I'm really not the one qualified to answer this but how are you going
to tell it to do X if it's true or Y if it isn't?

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
