ONCO on September 23, 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.

A quiet start

ONCO closed the day before at $0.68. On the 23rd, almost nothing traded early. The pre-market high was $0.68 at 7:23 a.m. Just 5,588 shares traded before the bell.

It opened at $0.68. Our data shows no headline for the day, so the run that followed came with no news we can point to.

The afternoon run

The stock sat near its previous close until the afternoon. Then, from $0.67 at 2:51 p.m., it ran to $0.88 at 3:02 p.m., up 30%.

Stop It's 3:07. ONCO is at $0.94, against a $0.68 previous close. It ran hard over the last few minutes, and $1.00 is just above. Would you buy here?

At 3:07 it traded through $1.00 for the first time. From $0.76 at 3:04 p.m. it ran to $1.01 at 3:07 p.m., up 33%. At 3:07:48 it was halted (a volatility pause) with the last trade at $1.01.

The reopen and the swings above $1.00

It reopened at 3:12:48 at $0.91, 10% below where it stopped. The first print was one trade of 126,977 shares at $0.909. It fell to $0.81 at 3:12 p.m., down 20% from $1.01.

Then it swung hard. From $0.83 at 3:13 p.m. it ran to $1.05 at 3:14 p.m., up 27%. It fell to $0.84 at 3:15 p.m., down 20% from $1.05. From $0.85 at 3:16 p.m. it ran to $1.10 at 3:20 p.m., up 30%. By the end of the 3:20 p.m. minute, more shares had traded than exist in the whole float (4.38 million).

From 3:23 p.m. on, a large bid sat at exactly $1.07. By then the stock was trading near $1.10, so the bid sat just under the price.

Stop It's 3:24. ONCO is at $1.09. A large bid has been building at $1.07, just below, since 3:23. Would you buy here?
