Hi,
For the difference between equivalence (==) and assignment (=) you can read the user guide here: http://www.amibroker.com/guide/a_language.html
An observation;
Since you are reassigning Filter within a loop, without using an OR operator, each iteration of the loop will clobber the previous Filter setting such that the last iteration will always win.
You probably want to initialize Filter to false and then do something like the following in your loop:
Filter = Filter OR ...
Also, what you appear to be trying to do can likely be done by using the "use filter" setting of the "Apply To" section in the AA window. Would that be enough for you, or do you specifically need to do this in code?
