My nibble trade is the only one today (only 22 contracts) so you can see what I paid, $3.41. I put the market trade in knowing Etrade works the price, which was 20 cents lower than the Ask.
I'm holding this position for a while. At $9 or so, I don't lose money on a trade sell, at $9.50 or so, I'm even with the stock gain. Ariad should be NDAing '113 this year, and that drives us past $10. By expiration we could see at least $11, and possibly much higher.
With a b/o, it's a big winner.
