The day before
On September 29, BIYA traded between $2.00 and $2.74 and closed at $2.05.
The news came after the close. At 4:28 p.m., PRNewsWire ran: “Baiya International Group Inc. Announces First Half of Fiscal Year 2026 Financial Results.” The last bar of that evening was $2.50.
Pre-market: the float traded by 4:33 a.m.
The first trades on the 30th were at $2.48, already above the $2.05 close.
From $2.48 at 4:00 a.m. it ran to $2.67, first reached at 4:13 a.m., the pre-market high. 1.51 million shares traded before the bell.
By 4:33 a.m., more shares had traded than exist in the whole float (787,731).
The price did not hold. A 16,667-share sell order went through nine price levels at 5:15:03 ($2.36 to $2.28), and the pre-market low was $2.25 at 5:15. By 9:28 it was back at $2.46.
The open
It opened at $2.45, up from the $2.05 close. The first minute traded 16,295 shares. The open did not lead to a run. It slid to $2.30 by 9:34 and was back at $2.43 by 9:42.
The wall at $3.00
From 4:26 a.m. on, someone was offering stock at exactly $3.00. It peaked at 37,170 shares at 9:34 a.m., about 5% of the float. The stock was trading around $2.30 to $2.40 in that minute, well below it.
Stop It's 9:43. BIYA is at $2.44. The last minute traded about 2,000 shares. A large ask wall sits at $3.00. It peaked at 37,170 shares at 9:34. Would you buy here?

At 9:45:18 trading at $3.00 began. In 6.7 seconds, 33,199 shares traded at exactly $3.00 and the wall was gone. It wasn't pulled. Buyers ate it.
The high of the day, $3.18, came in the 9:45 minute. That minute traded 314,028 shares. At 9:46:17 a 15,677-share sell order went through seven levels, $3.02 to $2.96, and the 9:46 minute dipped to $2.80.
The lower high
It tried once more. At 9:48:10 a 20,209-share buy order swept $2.99 to $3.01. Three seconds later a 15,152-share sell order went through ten levels, $3.02 to $2.93. The 9:48 minute reached $3.10, a lower high under the $3.18 top.
At 9:48:45 a new ask wall showed up at $3.00. It peaked at 56,594 shares (7.2% of the float) at 11:58 a.m. The stock was far below $3.00 by then. The 9:49 minute fell to $2.74, and sell orders of 16,459 shares at 9:49:31 and 14,345 shares at 9:50:15 pushed it lower.
The fade
It slid to $2.25 at 10:24 and to $1.90 at 10:35, the low after the open. A bid wall appeared at $1.90 at 10:36, and it peaked at 32,795 shares at 3:59 p.m.
From there it mostly held between $1.91 and $2.12. It closed the regular session at $2.00, 37% below the $3.18 high.
After the bell the price spiked to $2.10 in the 4:00 p.m. minute, then fell. It hit $1.68 at 4:04 p.m., the low of the day. No news is in the data for that move. After that it drifted between $1.76 and $1.95.
Regular-session volume was 3.22 million shares. With 1.51 million pre-market, that makes 4.73 million before 4 p.m., so the float changed hands about 6 times, at 47 times its normal volume.
What to take from it
- Here, a big ask wall at a round number was a level, not a ceiling. Here 33,199 shares traded at $3.00 in 6.7 seconds and the stock printed $3.18 in that same minute.
- After the top, the next push stopped lower. $3.18 at 9:45, then $3.10 at 9:48. The stock never got back above $3.10 in regular hours.
- The float traded over before the open, and the gap still faded. The open was $2.45, the high came 15 minutes after the bell, and it closed at $2.00.
