+<h3><a name="minprofit">Minimum trade value</a></h3>
+
+Often there are many low-volume, low-value trades.  It can be rather
+labour-intensive to buy and sell a dozen different commodities, half
+of which are only making a few poe each.
+
+<p>
+
+The "minimum trade value" specifies a minimum profit that you would
+like to get from each (commodity, collect island, deliver island)
+triplet.  Trades which don't meet this minimum will start out unticked in
+the "Relevant trades" table and will not be included in the voyage
+trading plan.
+
+<p>
+
+If you want to change your threshold, you have to select "Apply",
+which will automatically tick and untick all of the tickboxes for in
+"Relevant trades", as appropriate.  This will undo any customisation
+of the set of trades you have already done by manually ticking and
+unticking individual trades.
+
+<p>
+
+The value is an absolute poe amount, typically 5 or 10, representing
+the minimum profit to make it worthwhile (from a time and effort point
+of view) clicking in the YPP client to collect and deliver a
+commodity.  Setting a higher threshold will make each island visit
+faster, by excluding trivial transactions, and so reduce the chance
+that market conditions change adversely during your voyage.
+
+<h3><a name="poelimit">Caution about stalls' poe reserves</a></h3>
+
+If you select <b>Also be cautious about stalls' poe reserves</b>,
+YARRG will calculate a minimum amount of poe that each stall has on
+hand (by looking at all the offers that stall is making), and never
+plan for you to sell goods at that stall for more than the available
+poe.
+
+<p>
+
+Goods planned to be bought at the stall (which might boost the stall's
+poe reserves) are not considered, to avoid having to calculate the
+stall's cash reserves at various different times.

+<h3><a name="posinclass">Locating commodities in the YPP client UI</a></h3>
+
+In the Voyage Trading Plan, YARRG indicates after the commodity name
+where in the YPP commodity UI each commodity can be found.  First
+comes the initial letter of the category:
+%     my $dbh= dbw_connect('Cerulean');
+%     my $getclasses= $dbh->prepare(
+%        "SELECT commodclass FROM commodclasses ORDER BY commodclass");
+%     $getclasses->execute();
+<%
+    join '; ', map { $_->[0] =~ m/^./ or die; "<strong>$&</strong>$'" }
+        @{ $getclasses->fetchall_arrayref() }
+%>.
+<p>
+
+Then, if applicable, follows a number from <strong>0</strong> to
+<strong>9</strong> indicating roughly where the commodity is in the
+list of commodities of the same class.  The number indicates which
+tenth of the list is: <strong>0</strong> for the first (top) tenth,
+<strong>1</strong> for the 2nd, and so on, up to <strong>9</strong>
+for the final tenth.
+
+<p>
+For example,
+<blockquote>
+<table><tr>
+<td>Fine pink cloth&nbsp;&nbsp;
+<td><div class=mouseover
+ title="Fine pink cloth is under Cloth, commodity 14 of 55">C 2</div>
+</table>
+</blockquote>
+indicates that Fine pink cloth can be found under Cloth,
+between 20% and 30% of the way down through the types of Cloth.
+If you mouseover that in a suitably equipped browser you should see the
+text:
+<blockquote>
+Fine pink cloth is under Cloth, commodity 14 of 55
+</blockquote>
+<p>
+
+The position indicator digit isn't shown for very small
+categories.
+
+The exact location of the commodity in the actual game
+client may vary because YARRG only considers the list of all possible
+commodities, not the list of actual offers at the island in question.
