What happened
Draft for review. Not published.
The $3.00 wall
BIYA had no news in the data. Even so, it traded its whole 2.75M-share float by 4:13 a.m. For hours after that, sellers offered stock at exactly $3.00.
Stop It's 8:20. BIYA is at $2.53. Since 6:02 someone has been offering stock at $3.00, as much as 73,257 shares at the peak, for a stock with a 2.75-million-share float. Would you buy here?
Press play: the real Level 2, tape and chart run from 8:17 a.m. and stop at 8:20 a.m. ET for your call.
Buyers ate the wall. At 8:20:46, 45K shares traded at $3.00 in under a second.
It hit $37.10 in the 8:21 minute. By 9:15 it had fallen to $1.67.
The afternoon walls
It opened at $2.14 and sat near $2 all morning. By 1:03 p.m., sellers had stacked offers at $2.38 and $2.50.
Stop It's 1:07 p.m. BIYA is at $2.30. Offers at $2.38 have been building since 1:01, up to 79,415 shares at the peak. Another big offer, up to 101,675 shares, sits at $2.50. Would you buy here?
Press play: the real Level 2, tape and chart run from 1:04 p.m. and stop at 1:07 p.m. ET for your call.
Buyers took both. Starting at 1:07:24, 75K shares cleared the $2.38 wall. At 1:11:08 the $2.50 wall went too. It closed at $2.31.
What to take from it: On this day, broken walls led to fast moves, and fills often cost more than the screen showed.
