To carry a trade over a weekend you do not need to do anything during the current week, but DO NOT CLOSE OUT your trade.
During the weekend, submit the same pick and save it. Then go to Manage Pick and check the box there to “continue the pick.” This has to be done before the deadline on Sunday at 3:00 pm ET
The first week’s performance will be recorded as if you exited that trade on Friday’s close. That same number will count as the next week’s entry. You may continue a trade for any number of weeks.
