If you have chosen to use Internet updates for intraday quotes and your position list holds 25 or fewer items, Position Manager will automatically seek new data on a regular basis.
However, you may initiate additional updates from the Internet by clicking "Refresh" from the tool bar. New prices will immediately display in the table, and new valuations will be calculated based on the new data. Note that these are on-demand updates, as opposed to a streaming data feed.
If your Position Manager spreadsheet shows more than 25 items, the "Refresh" feature is the only way of updating prices with delayed intraday prices.
