Sorry, there may be, but I don't know one, and it's not otherwise easy. Like others here, the way I try to do it (when I try), is to pull up the specific options charts for the day, try to identify any trade spikes in question, and try to determine if the trades were done at the bid or the ask.
Also, open interest changes, which usually batch update at night (so they do not reflect the nature of the current day's trading), are also important. So tracking the open interest changes will indicate trending sentiment. Nothing easy about it, but might be worth it if you trade options.
Perhaps others here who trade options more regularly than me can weigh in. IIIman might have insight. I'll ask.
I think for the high risk investor, an option play here is worthy of consideration. I agree a big move in Ariad +/- a month of the AGM has become more likely with the delay and now the meeting moving to the attorney's office.
Some possible reasons include legacy BoD concern of the possibility of last minute, Denner-inpired, challenge proposals as happened at last years AGM, a b/o proposal, or some sort of security concern.
On the security matter, I quickly scanned and compared just the first few pages of this years proxy and last year's. Seems the requirements and restrictions this year are more emphasized. I also note that HB signed last year, DesRosier this year.
