I was able to get son's acct 45k shs @ .0099 in AM Friday right away but couldn't get 150k @ .01 all day until closing even though trades at .0098 & 9 were trading. Which shows everyone is holding on. Small amounts get traded easily larger amounts longer wait till broker can accumulate enough shares for transaction it appears. I was happy to get want I got, didn't look like I would score any. It was a all or none order didn't want to pay commission on a bunch of small trades. Bottom line if you want more better get them now. It's getting harder to accumulate when everyone not selling.
