I do not know how AB builds the weekly candles.
I always thought they were a Monday to Friday interval.
I really never looked into it because I never needed or used weekly charts.
I believe Tomasz wrote about that on this email group or it was on a AB version upgrade.
Anyway, if they do not start on Monday, I would create my own bars the same way we do with RENKO bars.
There are some Renko codes out there.
I can send you one if necessary.
So, on a Daily timeframe chart, it is possible to properly fill the weekly arrays starting every Monday and finishing on Friday (or, on a better code language: starting every time dayofweek() is minor or equal than its last value).

Thankt, but unfortunately it's not what I'm looking for... I'd like to have 4 weeks candles starting Monday and ending Friday (4 weeks later).On Mon, Mar 28, 2016 at 5:40 PM, portfoliobuilder99@gmail.com [amibroker] <amibroker@yahoogroups.com> wrote:[Attachment(s) from portfoliobuilder99@gmail.com [amibroker] included below]In your code you can identify the first trading day of every 4th week with the afl below.
