Ok, I'm sure the answer to this is "You need a vacation," but I just thought I'd ask. What are the odds that brokers on the desks at ToS, etc., share account info. with their erstwhile market-maker colleagues for NDX/SPX. etc.? I ask because, well, I've had some tremendous success with spreads on these index options over the last six months or so ... but, suddenly, I can't get filled -- ever. I know, I'm losing my mind. Again, just thought I'd ask.
