How does the "minimum trading days" rule works?

For some challenges, you may not need to have any active trading days (0), while others may require you to have at least 2 or 3 active trading days. This means you need to have open positions on separate days during the challenge to meet the criteria.

If the trade opened and closed on, for example, the 17th of March, that would count as one active trading day. However, if a trade is placed on the 17th of March and closed on the 20th of March, this still counts as one active trading day.
