Metastock weekly charts are updated only once a week. They are not a running
last 5 days chart. If you want a true weekly chart (including the last 5
days), you'll have to use something else, like Excel.
A suggestion. Why not have 2 folders with the same tickers, one for daily
charts and one for weekly charts?

in this example, the system would reference them statically - that is, as if
you've looked at weekly chart once a week, and not every day. And weekly
charts seen every day can and will change dynamically (and, with hindsight,
just like ZigZag function:-((}.
