GCDT on September 8, 2026, one-minute bars in New York time. Shaded: before the 9:30 a.m. open and after the 4:00 p.m. close. Bands: halts.

Pre-market and the open: almost nothing traded

The official previous close was $0.37. Only 11 shares traded before the bell, across three minutes. The pre-market high was $0.37 at 7:26 a.m.

It opened at $0.36 with 150 shares. The next trade was 100 shares at $0.36 at 10:01. After that, nothing traded until 10:15.

10:15: the headline and the first run

At 10:15 a.m. GlobeNewsWire ran: “Green Circle Decarbonize Technology Limited Entering into Strategic Partnership Agreement for Mass Production of BocaPCM-TES Panels in the People's Republic of China”. The first trade in that minute was $0.38, above the pre-market high. By 10:19 it had reached $0.52.

At 10:20 a.m. the company filed a 6-K (a foreign company's current report). The stock fell to $0.38 at 10:22, down 28% from the $0.52 high three minutes earlier.

Then it turned. From $0.40 at 10:23 it ran to $0.63 at 10:31, up 60%. The 10:31 minute alone traded 1.8 million shares. By 10:32, more shares had traded than exist in the whole float (7.19 million). It then slid to $0.43 at 10:44, down 32% from the top of that run.

The wall at $0.60

From 10:55 a.m. on, someone was offering a lot of stock at exactly $0.60. The stock was back near $0.54 by then, so the wall sat just above it.

Stop It's 11:06. GCDT is at $0.59. A large ask wall has sat at exactly $0.60 since 10:55. Would you buy here?

The wall peaked at 100,522 shares at 11:06:11, about 1.4% of the float. At 11:06:23 shares began trading at $0.60. In under a second, 154,871 shares traded at exactly $0.60 and the wall was gone. It wasn't pulled. Buyers ate it.

The run went on to $0.67 at 11:14, up 52% from $0.44 at 10:53. From $0.57 at 11:20 it ran to $0.86 at 11:30, up 51%. That $0.86 was the high of the day so far.

A second ask wall formed at $0.82 (about 104,000 shares at its peak). At 11:50 it was eaten the same way. About 108,700 shares traded there over roughly five seconds.

The drop to $0.63

It pushed to $0.83 at 11:45 and again at 11:50, then fell to $0.63 at 12:07, down 24%. By 12:12 that was ten times the float traded.

A bid wall at $0.61 also showed up. It first appeared at 11:37, vanished at 11:43, then came back at 11:43:50. It peaked at 157,200 shares at 12:37 and was pulled at 2:29 p.m. From 12:12 until 3:20 the stock held between about $0.65 and $0.79.

3:30: the $0.80 wall

A third ask wall had been sitting at $0.80 since 11:54 a.m. It peaked at 136,600 shares at 1:02 p.m. and stayed for hours. Late in the day the stock started to climb toward it: from $0.69 at 3:20 to $0.78 by 3:29.

Stop It's 3:30. GCDT is at $0.77. A large ask wall has sat at $0.80 since 11:54 a.m. Would you buy here?

A bid wall of about 105,500 shares appeared at $1.04 at 3:38. At 3:39 the stock pushed to $1.12, a lower high under $1.17. At 3:40:39 a 98,874-share sell sweep went through, and the wall was gone a second later. The 3:40 minute dipped to $0.98.

It kept fading: $0.94 at 3:54, and $0.93 at the close.
