Question: What does the "and open next trade at normal time" and "re-open immediately" mean?

If a trade is re-opened "at normal time" it simply means when the option would have expired, re-open the position. Re-open immediately, means at the end of the same trading day, open the position up with the same logic (such as 30 days to expiration, 40 delta, etc) as when the trade was first opened.
