Richard,ANY other function works just fine with my
valuable Amibroker 4.06.Just fine.I can not see the reason for this
P&F script.Anyway, the author perhaps could expain.Dimitris

I agree it was not easy to understand. The attached charts showed
the TWO results that were generated whenever I entered the symbol MSFT -
it appears to be a fluke and I cannot reproduce it any longer.
Although there is not ticker name in the formula, there was strange
behavior occurring for MSFT and MSFT only at that time.> > The
gist of my reply to you was that using the SAME code as you posted and
using the code I copied from the files sections, I generated the same
results - and not the results that you were creating. That suggests
that you have a problem in your data and/or setup. The only reason
for the two codes was to guarantee that there wasn't a subtle error -
there was not.> > Sorry for adding the confusion about the MSFT
