That's my preferred strategy: http://optioncreator.com/short-strangle Btw, the option creator web application (requires javascript enabled) at the above site has helped me much. I can recommend it to all option traders...
I'm positive that this is false. MM alter their models and discount prices before the weekend to avoid exactly what you claim to experience and being stuck with theta losses.
So, you mean the MM rises the Ask and lowers the Bid? Then people who entered positions some days/weeks ago will be happy.... It doesn't sum up, man!
People are so sensitive and touchy about trading discussions -- it's like it's Politics or something. Most people who fail at something themselves, usually always deeply resent others for either trying or (god willing) even succeeding.
