How to estimate the completion time?

Real-time period (5*24h)

17:15~17:00 EST (Sunday~Friday)

non-real-time period

The exchange request which is created during the weekends will be completed in the next real-time period. For example, you create an exchange request on Saturday. it will start exchange at 17:15 on Sunday. (The arrangements of holidays will be notified separately. Please pay attention to relevant announcements.)
