Going into the close this afternoon, I was short a May 930/960 call spread in AMZN. When I logged in near the close to close the position, I discovered that the position had already been closed for $30.55 (likely at the natural?). I’m not fussed about the auto-liquidation itself as my long leg was at risk of being pinned, but surely this could have been closed for $30.00 or even $30.01.
It’s only $0.55 but do I have a valid beef?
