Why is that?

[DivideByZeroError]

There was something amiss in the configuration of the selection on that day, which was also causing the ERROR_IN_MATCHER problem I posted about.

I didn't get any explanation but the market was suspended for a while the next morning and then eventually sorted out at some point during the day.
