How much do 500 shares cost? There are 2 trades with 500 shares and 1 with 100. After the price goes to .0025 he enters to be filled at .0029, either to make his statement better or, I'm not sure why.
Many times at the end of the day, since the closing price is what the accounts are valued at, you will see traders that are just to make someone feel better or dress up the nightly statement or weekend statement.
For $20 someone can easily make this stock look better, that's why it's called painting the tape.
I hope I explained it. You will notice it often, especially on Fridays when traders want to feel good about their holding...
