the exchange is in your local zone then there’s no difference, but if you’re
elsewhere then the exchange zone has the advantage that you can see where it
is in the trading session, eg. early on, the close, etc.  It’s easier to
remember opening and closing times at the exchange than local equivalents
(especially when daylight savings affects them).

<p>The View/Intraday menu entry (<kbd class="key">Ctrl-I</kbd>) or the Intraday button in the
watchlist (see <a class="pxref" href="#Watchlist">Watchlist</a>) opens an intraday image window for the current
symbol, showing trading today, or so-far today.
</p>
<p>Alas there are no longer any data sources with intraday images.

<p>The Tools/Download menu entry opens the download dialog.  Choose &ldquo;What&rdquo; to
download, either all symbols, the favourites list, or a particular symbol.
</p>
<p>The default is an update of all symbols.  This is usually what&rsquo;s wanted, to
get all latest data.
</p>
<p>Click on the &ldquo;Start&rdquo; button to begin.  The top box is the subprocesses
running, the middle box is the jobs running or queued, and errors are shown in
the lower text window.  If you&rsquo;re offline the errors will usually be &ldquo;host
name lookup failure&rdquo; or &ldquo;network unreachable&rdquo;.  To abort select the job in
the middle box and click on &ldquo;Stop&rdquo;.
</p>
<p>The main chart display can be used while downloading, for instance to look
immediately at the first few symbols updated while the rest are still going.
Sometimes a database update can make the GUI block for a moment.

<p>In the main Chart window, <kbd class="key">Ctrl-U</kbd> starts an update download for the
currently viewed chart.  This is a good shortcut to grab new data for just one
symbol.  Download progress is shown in the main window statusbar (as well as
the download dialog).

<p>You can run &lsquo;<samp class="samp">chart --download</samp>&rsquo; to do a command-line (non-GUI) download
(see <a class="pxref" href="#Invocation">Invocation</a>), for instance in a script perhaps when first going
online, or at selected times.  Progress messages are shown if the output is a
terminal.
</p>
<p>Care should be taken not to hammer the various data sources when automating
downloads.  Keep update attempts to times when there should be new data, and
don&rsquo;t retry endlessly.
</p>
<p>Chart tries to know when to expect new data, and will do nothing in an update
until then, but this is often imperfect.  Public holidays (with no data) are
not tracked, and it&rsquo;s easy for a data source to be delayed unexpectedly.
