When creating a League Manager (LM) league you can choose different trade deadlines for the available dates/times. 
Public Standard League trade deadline : Aug 19, 2022 @ 12:00 PM EDT 
Private leagues trade deadline: All Mondays @ 12:00 PM EDT, latest being Oct 3, 2022 (or no trade deadline)

After the trade deadline has passed, managers will NOT be able to send/accept trade offers to other teams. 

You might ask, "What if I propose a trade near the trade deadline, how would that work?" 
Here is a breakdown of how it would work with different scenarios.

NOTE: The default Trade Deadline for the season is 12:00 pm Aug 19, 2022, EDT

Scenario #1
Public League - 1-day trade review period

Team A proposed a trade to Team B on Aug 18, 2022, at 7 pm EDT, and Team B accepted the offer at 8:30 pm EDT the same day. (would process Aug 19, 2022, 8:30 pm EDT.
Other teams will have until the trade deadline (Aug 19, 2022, @ 12:00 PM EDT) to either vote to uphold or veto the trade. After the deadline, If the trade does not have enough veto votes, it will process as normal on Aug19, 2022 8:30 pm EDT.

Scenario #2
Public League - 1-day trade review period

Team A proposed a trade to Team B on Aug 19, 2022, at 11:15 am EDT and the manager of Team B does NOT see the offer till 1 pm EDT the same day. 
Team B will NOT be able to accept the offer as the trade deadline has passed. The trade will automatically disappear when it expires. 

Scenario #3
Private League - 2 day trade review period

Team A proposed a trade to Team B on Aug 18, 2022 2 pm EDT, and Team B accepted the offer at 8:30pm EDT the same day (would process Aug 20, 2022, 8:30pm EDT )

Other teams will have until the trade deadline (Aug 19, 2022, @ 12:00 PM EDT) to either vote to uphold or veto the trade. After the deadline, If the trade does not have enough veto votes, it will process as normal on Aug 20, 2022, at 8:30 pm EDT.

If League Manager wants to bypass the trade review period, it must be done BEFORE the trade deadline. 

For League Managers that want to uphold/veto the trade after the trade deadline has passed, they will need to extend the trade deadline. Please note the deadline CAN NOT be reverted back to the original.

SUMMARY

• Trades must be ACCEPTED by the trade deadline

• Voting must be done PRIOR to the trade deadline

• LM vetoes/upholds must be executed PRIOR to the trade deadline
