The day before

On October 6, BIYA traded between $1.30 and $2.48. The official close was $1.37.

After hours the last bar of that day was $2.33. No news headline is in the data for the 7th.

Pre-market: the float traded by 4:13 a.m.

The first trades on the 7th were at $2.09, already above the $1.37 close. The float is 2.75 million shares.

The 4:13 a.m. candle jumped from $2.13 to $2.84 on 819,419 shares. By the end of that minute, more shares had traded than exist in the whole float. By 8:19 a.m. that was ten times the float.

Then it went sideways for hours. From 4:14 a.m. to 8:19 a.m. it traded between $2.02 and $3.10, mostly between about $2.35 and $2.99.

The wall at $3.00

These are order-book levels, not visible on the candles. Stock was offered at exactly $3.00 twice before the bell.

The first wall was seen at 4:20 a.m. It peaked at 85,060 shares at 4:55 a.m., about 3% of the float. A buy sweep of 67,276 shares ran from $2.80 to $2.88 at 4:54. At 5:38:49 a.m., 53,250 shares traded at exactly $3.00 in that one second and the wall was gone. The 5:38 candle touched $3.10. The next minute closed at $2.95.

A second wall appeared at $3.00 at 6:02 a.m. It peaked at 73,257 shares at 8:12 a.m. Meanwhile the stock traded between about $2.34 and $2.80.

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?
