What does not work?
You may get more than 3 races?
In this case, you could use:
<dtml-in .... sort=closingdate reverse> <!-- this sorts with latest closingdate first
-->
<dtml-if "closingdate > ZopeTime() and _.getitem('sequence-number') <= 3">
.... your presentation code ....
</dtml-if>
</dtml-in>
This will give you the list sorted with decreasing closingdate.
If you want a list sorted with increasing closingdate, you could use:
<dtml-in .... sort=closingdate>
<dtml-if "closingdate > ZopeTime()
and (_.getitem('sequence-length') - _.getitem('sequence-index')) <=3">
.... your presentation code ....
</dtml-if>
</dtml-in>
For more details, look at the variable list defined inside <dtml-in>.
