Hi Terry,
in IB, Status("firstvisiblebar") returns a number and it can be used
as a base to count backwards or forwards and do operations based on
the bar-number.
Thank you to welcome me in the world of programming :-)) but I
actually have a programming experience of 15 years in Pascal, IDEAL,
FoxPro and VisualBasic. But never coded something thats close to C++
As in AFL brackets are used instead of ENDIF or END IF or ENDLOOP or
LOOP or NEXT it is less readable for me and I have te get used to it
more and more. Whats also a problem for me, the syntax errors are
not only for syntax-checking also for the reasonability of the code,
like, can a index like "i" become a negative number and therefore
being out of range. But it does not explain the syntax error, is it
wrong written or is it the bad logic, which in other programming
languages leads to runtime errors that can only be found out by
debugging (or hard thinking before coding).
So, one of the most useful abilities of AFL is also one of the most
time consuming aspects for a beginner in AFL. Unless there would be
more specific explanations in the Syntax-Error window that pops up.
Regards
enzo
Some days I spent
