The day before
On August 31, RDAC traded between $4.50 and $5.45 and closed at $4.56. Volume was light, about 16,000 shares. After hours the last trade was $5.22, already well above the close.
Pre-market: a spike at 4:07, then a long fade
The first trades on the 1st were at $5.31, above the $4.56 close. For five minutes it drifted around $5. Then at 4:05 it started to move.
The 4:06 candle ran from $5.52 to $7.29, on 66,092 shares. The pre-market high was $7.98 at 4:07 a.m. Then it turned. By 4:12 it was at $5.42, down 32% from the high. A bounce to $6.35 at 4:14 failed too.
From there it bled lower for two hours, with little volume later on. It hit $4.45 at 6:06 a.m., below the previous close and the low so far. 1.08 million shares traded before the bell, and about a quarter of that came in the first 10 minutes. There was no news in our data.
Open, then an hour of nothing
It opened at $4.90, up 7% from the close. The low since the open was $4.58 at 9:42. For the next 40 minutes it sat between about $4.58 and $4.97, with thin bars. Many minutes traded under 1,000 shares.
At 10:07 volume started to build. It pushed through $5 at 10:08 and reached $5.41 in the 10:10 minute, on 13,894 shares.
The halt at 10:11
The 10:11 candle ran to $5.65, on 23,317 shares. At 10:11:46 it was halted (a volatility pause) with the last trade at $5.65.
Stop It's 10:16. RDAC last traded at $5.65 and has been halted since 10:11. It is about to reopen. It was around $4.80 an hour ago. Would you buy the reopen?

It reopened at 10:16:46. The first print was 10,580 shares at $5.85, 4% above where it stopped.
The 10:17 candle hit $6.68, up 14% from the reopen price, on 138,526 shares. At 10:17:28 one sell order swept 25,209 shares from $6.44 down to $6.07.
The wall at $7.35 and the chop
At 10:18:17 a wall of 50,000 shares appeared for sale at $7.35, about 1.5% of the float. It was pulled at 10:24:51. The price never reached $7.35 in that window. It topped at $6.93 at 10:20.
At 10:28 it fell to $5.91. At 10:32 it was at $5.64. Then it ran again, to $6.87 at 10:35, up 22%. By 10:45, counting the pre-market, more shares had traded than exist in the whole float (3.44 million).
Back above $7
At 10:43 a buy order swept 20,391 shares from $6.86 to $7.10. The 10:43 minute traded 177,160 shares. A 23,795-share print followed at $7.00, at the bid, at 10:43:35. It dropped back to $6.40 at 10:47.
From $6.58 at 10:50 it climbed to $8.56 at 11:02, up 30%. It pulled back to $7.52 at 11:08, then pushed again.
Stop It's 11:10. RDAC is at $7.89, up from $4.90 at the open. It ran from $6.58 to $8.56 in the last 20 minutes and then pulled back to $7.52. Would you buy here?

The high of the day was $8.59 at 11:11. The 11:11 candle closed at $8.27, and the next candle's low was $8.05.
The bid at $6.10 and a lower high
At 11:03:38 a bid appeared for 50,810 shares at exactly $6.10, about 1.5% of the float. It sat well below the $8.30 price at the time. Two more large bids followed: $6.02 at 11:16 (peak 50,268 shares) and $6.51 at 11:31 (peak 34,994).
After the high it slid. At 11:28 it pushed to $7.89, a lower high under $8.59. By 11:33 it was at $6.94. A bounce to $7.26 at 11:43 stopped lower again.
The $6.10 bid was pulled at 12:04:43, with the stock at $6.79, well above it. The $6.02 bid was pulled at 12:32:34. The $6.51 bid was pulled at 11:46:11.
The rest of the day
From noon it settled into a $5.76 to $6.96 range. A 22,495-share print at $6.58 hit the bid at 1:49 p.m. At 2:32 p.m. a buy order swept 28,587 shares from $6.50 to $6.90 and the stock reached $6.96. The low of the afternoon was $5.76 at 1:08 p.m., and it closed the regular session at $6.63, nowhere near the high.
After hours it traded up to $7.06 at 4:51 p.m. and was at $6.65 at 7:59 p.m. 193,513 shares traded after the close. Our data shows no news that day.
By the close, 9.28 million shares had traded in the regular session, and the float had turned over about 2.7 times. The whole day was about 17 times normal volume.
What to take from it
- A halt can reopen higher than it stopped, and the book can be very thin right then. The 10:11 halt stopped at $5.65 and reopened at $5.85. A 5,000-share buy one second later cost $383 more than the screen showed.
- After the top, the pushes stopped lower. $8.59 at 11:11, then $8.56 at 11:14 and $7.89 at 11:28. Big bids below the price at $6.10 and $6.02 were pulled later.
- A pre-market spike can fade fast. The 4:07 a.m. high of $7.98 was gone by 4:12, and the stock hit $4.45 before the open.

How it traded
Intraday run. It opened up 7.5% at 4.90, then ran from the open to the high of 8.59 in 101 minutes through a halt.
| Time (ET) | What happened | Watch it |
|---|---|---|
| 4:05 a.m. | First trade 20% above the previous close of 4.56 | |
| 4:07 a.m. | Pre-market high, 7.98 | |
| 9:30 a.m. | The open: 4.90, up 7.5% from the previous close | |
| 10:11 a.m. | Halted: LULD pause (limit up-limit down). Trading resumes at 10:16 a.m. | |
| 10:45 a.m. | Volume since 4:00 a.m. passes the whole float, 3.44 million shares | |
| 11:11 a.m. | High of the day to the close, 8.59 | |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 6.63, 22.9% below the high |
The shape is a fixed rule, not a judgement: gapped 10% or more at the open, ran 10% or more from the open to the high, and faded if it gave back 30% or more of that move by the close.
The day in numbers
- Volume, from the one-minute bars: 1.08 million shares before the 9:30 a.m. open (10%), 25,966 in the first 30 minutes (0%), and 9.45 million in the rest of the day to 8 p.m. (90%).
- Float rotation, the volume since 4 a.m. against the float of 3.44 million shares: past it once at 10:45 a.m., twice at 11:18 a.m., three times at 3:47 p.m.
- The halt at 10:11 a.m.: up 17.0% in the 5 minutes into it, reopened at 5.85, up 3.5% from the last trade before it, then up 15.2% over the next 5 minutes.
