The day, step by step

The day before

On October 9, YMAT opened at $1.27 and ran to $3.69. By the official close it was back at $1.28, about where it started.

Pre-market: the float traded in the first 11 minutes

The first trades on the 12th were at $2.72, already far above the $1.28 close. The first minute reached $3.32.

By 4:11 a.m., more shares had traded than exist in the whole float (2.70 million).

The pre-market high was $3.88 at 5:51 a.m. After that it drifted down: $2.97 at 7:01, a bounce to $3.45 at 7:06, then $2.61 at 7:47. A short spike to $3.19 at 8:03 and a dip to $2.51 at 8:40 followed. 25.38 million shares traded before the bell.

The open: down to $1.95

It opened at $2.55, up 99% from the previous close. The first print was 28,403 shares at $2.55.

The book showed a bid wall at $2.07, up to 49,825 shares, from the open until 9:33:12. The 9:33 candle low was $2.10. Then the wall was gone.

The stock slid to $2.14 by 9:38, bounced to $2.40 at 9:40, then fell again. It hit $1.95 at 9:55, the low so far. Counting pre-market, about ten times the float had traded by 10:00.

The first halt

After about half an hour between $2.01 and $2.32, it jumped in the 10:29 minute. At 10:29:57 it was halted (a volatility pause) with the last trade at $2.81.

A bid wall at $2.81 appeared at 10:29:44 and peaked at 66,292 shares at 10:29:56, just before the halt. During the halt an ask wall appeared at $3.39, 56,143 shares at its peak. The $3.39 wall was gone by 10:36:38.

It reopened at 10:39:57 at $2.99, above where it stopped. The first print was 199,549 shares at $2.99. One buy order swept through 28 price levels, from $2.82 to $3.10. It reached $3.20 at 10:40, then fell. The $2.81 bid wall was eaten at 10:40:35, and the price fell to $2.67 by 10:42.

The wall at $3.03

From 10:41 on, a large ask wall sat at exactly $3.03.

Stop It's 10:44. YMAT is at $2.97. Since 10:41, a large block of shares has been offered at exactly $3.03, just above. Would you buy here?

At 10:44:48 one buy order swept 87,984 shares through 21 levels, from $3.16 to $3.36. The 10:44 candle closed at $3.57. A bid wall appeared at $3.57 at 10:44:56 and grew to 156,052 shares, 5.8% of the float, by 10:45:01. At 10:45:10 it was halted (a volatility pause) with the last trade at $3.57.

The fade and the close

At 10:57:58 an ask wall appeared at $4.00. It peaked at 73,384 shares (2.7% of the float) at 11:19:59. The price never got back to $4.00.

From there it faded: $3.06 at 11:00, a $3.43 bounce at 11:08, and a drop to $2.89 at 11:11 on two sell sweeps of about 51,000 and 55,000 shares. It reached $2.57 at 11:43 and $2.32 at 1:59 p.m. A 60,418-share buy sweep hit at 2:46:49 p.m., and the spike topped at $3.20 at 2:47. It closed at $2.84.
