Check the formula and make sure you are using "Portfolio Equity" formula and NOT "Individual Equity".

It used to work fine before. Maybe it's because I'm running on 1-minute with lot of signals and it happens when I click on the portfolio equity tab...

In fact, when I manually open AB database's folder, I see each and every ticker. Are you sure the data is in the Metastock files at that point?

Hence, I am running on a local database and what takes like 3-4 seconds is scrolling through the 1-minute bars. Let's say it is Day 1 at 11:00 and I want to scroll back to Day 0, I use my mouse wheel but for 3-4 seconds the images does not move at all, then I hear my computer loading, then I see the bars before. Is there a way to make that faster? > > Thanks, > > Louis > > > 2008/7/15 Tomasz Janeczko <[EMAIL PROTECTED]>: > > > > Hello, > > No, it does NOT take 3-4 seconds to load each ticker.
