I am using QuickFix/n v1.10.0 to establish daily sessions for weekdays only. As answered in this question, I tried using Weekdays configuration key but it doesn't seem to be supported in this version of the library, which is currently the latest one.
Documentation describes the configuration for sessions lasting more than a day, but there are no words about this issue.
Is there an easy configuration for this functionality?
It is not a feature in QF/n right now.
