Here is the problem. You are waiting for the trade to 'go through.' But trades don't just happen. Someone has to take the other side. I assume you understand that there is no one who will sell the calendar spread to you at a premium of ZERO. It's not going to happen. There is a very remote possibility that for one brief instant in time that the Aug option will be 25 cents (or any other price) bid while the Sep option is offered at the same price. If that unlikely event happens everyone will attempt to grab that spread at zero. If your order is in place, there is a chance you will get to be the buyer. But don't count on it. It doesn't matter if one option, then the other, keeps trading at 25 cents. The only way you can get this spread for nothing is to take the leg - and that means buying first and hoping to sell afterward. That's not what you want to do (most of the time). Mark
I assume you are right (as it has not gone through yet) been pending for 2 days. I may try putting it in for 1-2c diffrence and see what happens.
also it does'nt need to be from the SAME buyer and seller, so in theory it could happen, I get that it would be quite rare. More thinking theoretical vs reality
