The iif() does not give the same result because
ref(inlongpos, -1) == 0 except when the previous bar is a buy.
You can see exactly what is happening
graphically with
buy =
sell =
inlongpos = iif(...
plot(c, "", iif(buy, colorred, iif(sell, coloryellow,
colorpalegreen)), stylebar);
title = "inlongpos = " + inlongpos + "
ref(inlongpos..." + ref(inlongpos...) + " buy = " + buy + " sell ="
+ sell
If you want the iif() approach to hold either a buy or
sell value for each bar additional code is needed to create this
condition.

Sure. This of course if part of an AFL with Buy
and Sell defined. Also an init for InLongPos
being set to zero as a starter. Again the ForLoop
works fine. I checked that with following statement : AddColumn(InLongPos,"Long",1);
My problem is that I do not understand why the
first statement does not give me the correct answer where the second does
...

Is there more to the code? Are you getting a
syntax/initialization error? How are you handling the case when i
== 1?
