I am not new to Ami, been using it since 2003. But at times the array
processing drives me nuts. I tried to use barssince and looked at the buy and
sell arrays before they were set. so they were still nulls even when I
initialized them to buy = sell = 0;
But to try to understand what the arrays were doing I wrote a stupid little
program to see what was going on. The code is below.
What I am trying to do is save the highest hi in an array called theHi. I set
the first cell in theHi to the value of in the first cell of the close. Then I
compare them but theHi follows the close even when the close goes down.
Then I wrote the same function in a for loop and it works fine.
Then I added the formula to Excel and it worked correctly.
=IF(C3>D2,C3,D2) where C has the close and D the hi array values. Here I also
set the hi in cell 2 to the first value of Close.
SO excel works fine with the same formula as Afl but Afl fails.
I must be missing something really basic. Can anyone tell me why Ami won't
allow me to scan through the close array and save the high?
Thanks,
Barry
