Re: [amibroker] How to initialise variable?

["Tomasz Janeczko" <amibroker@xxxx>]

Hi,

The formula you wrote
value = IIF(H>C, Ref(value, -1), 1);

is self-referencing (MS uses PREV for this). 
This does not work in pure AFL.
You should either use AFL scripting for this
or rewrite formula to use functions like Cum(), ValueWhen().
In most cases it is possible to write your formula
without self-referencing statements.
BTW: Your example formula returns "1" always.

Best regards,
Tomasz Janeczko
