I have an existing SPX call vertical that I am attempting to roll using a butterfly. The order is BUY +1 BUTTERFLY SPX 100 (Weeklys) 23 JUN 23 4425/4435/4445 CALL @.40 LMT. The order is rejected with the message "Order position effect could not be safely calculated". TOS support says "too bad, that's the way it is". Well, this is not the way it has always been; I have executed this type of order many times over the years. Is anyone else having this problem? Thanks!
