Close at 50% of max profit

What is tastylive's published profit target for a calendar spread?

• 50% of maximum profit, as for condors
• About 25% of the debit paid
• There is none; calendars are held to expiry

Your condor's 50% target and its 21-day exit could both apply. Which one ends the trade?

• Always the profit target
• Always the 21-day exit
• Whichever comes first
