I have had a 20M order filled in the course of my shares accumulation. 999,999 is not unusual if your online trading account doesn't allow penny stock transactions for a million or more shares, as is the case with my Vanguard Brokerage Account. My son-in-law filled for 10M this week at .0001. 911 and 100 are alleged to be signals among traders, as per several recent posts.
