Updating missing intraday data with eSignal

If I disconnect for a day, when I connect again my charts are missing a day's data. I have tried using the downloader, which attempts to update them but ends with "No securities were updated, errors occurred."

It sounds like you are using local data. These files only get updated when the data/file servers and the data manager are running. There isn't an easy way to fill in the gaps. The DownLoader can only update EOD securities, not intraday.  You want to use DataOnDemand.

- Save the attached file to your DownLoader folder (C:\Program Files\Equis\The DownLoader, by default), then restart MetaStock

- Go into the Open dialog

- Select the eSignal button

- Select the desired symbol, select the periodicity in the lower left screen

- Click Open

These charts will automatically do the data management for you.
