This also means that you canât exercise your long (back month) leg to offset the short (front month) leg if it happened to be ITM at its expiration. To a great extent you are naked without the back monthâs hedge. You will have to cough up the cash for the short leg (if ITM) and in the meantime a whipsaw action might very well bring your long (back month) leg to OTM, at its expiry-- leaving you with a net loss. There is a reason why these âtime-spreadsâ are so âcheapâ.

Quote from yip1997:
Ben,
Why would European options make a calendar spread riskier than American type options? I thought European options didn't have the risk of early exercise. Can you elaborate on this issue?
