Another "Poof" and its gone. WEED closed at $32.52 CAD that should equal $24.84 USD but TWMJF closed at $24.49 The derivative should mirror the price of the underlying.
Never mind. I get it now, its the last trade of TWMJF for the day was not the last trade of the day for WEED which closed at $32.52 therefore the value of TWMJF is now greater than its last trade.
