Hello,
Yes. Exactly like in C.
However there is one caveat in this approach.
If you write
my_variable = 5;
you can use
buy = my_variable;
and it will be interpreted as "true" value and it will give a
buy signal every bar.
But if you write
buy = my_variable == True;
It won't because True constant has a numerical value of 1 and
my_variable is 5 and 1 != 5
For that reason one should be very careful when mixing
numerical and boolean statements
(in C/C++ it works the same)

If I
follow you, a value less than zero would also be interpreted as true,so
in the example below the two versions of fromlongtoshort would not be
equivalent. Is that correct?

Re: [amibroker] numeric values in boolean expressions
Hello,
In fact numeric values can be treated as booleans as in
C.
Zero is interpreted as False, any non zero value (except
empty/null)
is treated as True.

It
depends if the variable yesterdaylongpercent is a true/false variable. For
example;
<SPAN
class=935453319-10022003>
<SPAN
class=935453319-10022003>x=c>ma(c,50); x is either true (1) or
False (0)
<SPAN
class=935453319-10022003>
<SPAN
class=935453319-10022003>x=ma(c,50); x is a variable number and
can not be equated to true or false.

numeric values in boolean expressionsCan numeric
values be used in a boolean expression?For example, are the following
two lines of code equivalent?fromLongToShort = (yesterdayLongPercent
> 0 AND todayShortPercent > 0);fromLongToShort =
(yesterdayLongPercent AND todayShortPercent);I am unable to try a
quick test at the moment.Thanks,-StevePost
