When I leave JBT running past trading hours my EventReport fills with these
messages:

I noticed this problem when I was collecting data from Eurex exchange, I'm
not sure if same thing happens with Globex but I will try to test it.

At first I thought that this bug does not affect other data streams but this is 
not
the case. When I'm collecting data for European and U.S market products at the 
same
time, data will stop coming at the end of euro session even though U.S data is 
still
available.

This piece of code gets rid of the exception but then price goes close to zero 
and it
doesn't look good on a chart.

 if (Double.isNaN(averageBalance)) {
       averageBalance = 0;
     }
