    Guides/8. Scanner

    Guide 8.2

    Scan types: momentum, running up and setups

    Intermediate, 8 min read. Checked with Scalpel 1.12.8 on October 15, 2026.

    In short

    Every Scalpel scan watches the IBKR scanner's list. High of day momentum shows any listed stock breaking its high of day, pre-market included, for a minute after each break. Running up shows stocks in a sharp burst (up 2% inside the last minute on 5 times their recent volume) and is the only scan with filters of its own. Setups shows stocks with a live entry pattern, such as gap and go or a micro pullback, marked with a coloured letter chip.

    Scalpel has four scan panels, and they are not four separate searches of the market. The IBKR scanner builds one list of movers (guide 8.1); the other three watch every name on that list, second by second, and call out the moments that matter for a long entry: a new high, a sudden burst, a pattern completing. This guide explains what each one looks for, Running up's filters, the six setup letters, and exactly when each scan alerts.

    Before you start

    • The IBKR scanner switched on and a scan desk open (guide 8.1).
    • To switch a panel to another scan, use the dropdown in its title (guide 8.5).

    The four scans at a glance

    Running upIt is up 2% in about a minute on a volume burst, and passes the filtersYes, in the cogOffNew runner
    SetupsIt has a live entry setupNoneOnThe setup's name

    High of day momentum and Setups have no filters because the IBKR scanner's list has already done the filtering: if a name is on the list and it triggers, you see it.

    High of day momentum

    This is the "it's breaking out" panel. A stock shows up the moment it trades above its high of day, in any session, pre-market included, and stays on the panel for 60 seconds after its latest new high. A stock grinding to a new high every few seconds is one entry, not a stream. Once it goes a full minute without a new high it drops off, and the next break adds it back and alerts again.

    The high it measures against is real. When a name joins the list, Scalpel reads today's high (pre-market included) from IBKR's 1-minute history, so a stock added at 10:15 does not "break" a high it was already above at 09:40.

    Running up

    This is the "something is happening right now" panel: a sudden burst of buying, whether or not it is at a new high. A stock shows when, at the same moment:

    • its price is up at least 2% over roughly the last 60 seconds (fixed, not a setting), and
    • this second's volume is at least Min rel volume (x) times its average over the last 30 seconds, and
    • it passes every filter in the panel's cog.

    Open the cog on the Running up panel to set them. Changes apply as you type: there is no Apply button.

    Max shares out10MShares outstanding must be under this
    Min volume100KShares traded today
    Min market cap ($)0No floor
    Max market cap ($)EmptyNo ceiling

    The share, volume and market cap boxes take short numbers: 500K, 10M, 1.5B. A stock whose shares out or market cap is not known yet passes those two filters, so a missing number never hides a mover.

    Require news catalyst, in the Global block, makes Running up show only stocks with a headline in the last 24 hours from the news providers on your IBKR account. It applies to Running up only.

    Careful

    Require news catalyst reads headlines through intel. With intel switched off (guide 9.1), no stock has a headline on file, so Running up shows nothing at all.

    High of day momentum and Running up both rank their rows the same way: stocks on a green 1-second bar first, then those with fresher news, then the bigger current volume burst, then the bigger percent change. Each shows its top 25.

    Setups: the six letter chips

    Setups shows any listed stock with a live entry setup, marked by a coloured letter beside the symbol. The pattern names will be familiar if you have studied the momentum style Ross Cameron teaches at Warrior Trading; Scalpel is independent and not affiliated with or endorsed by either.

    ChipSetupWhat triggers it
    G (green)Gap and goThe first cross above the pre-market high after the 09:30 open. Once per stock per day
    M (blue)Micro pullbackA shallow pullback during a fast move, then a reclaim of the recent high on volume
    H (yellow)HOD breakA new high of day in regular hours, when nothing stronger is live
    F (light green)Bull flagA strong push (the pole), a tight, shallow pullback, then a break over the flag's high
    T (lilac)Flat topA shelf of near-equal highs, then a break above it
    R (orange)Consecutive runFive or more green 1-minute candles in a row, then the first new high after the run

    When two setups fire at once, gap and go wins, then the candle patterns (bull flag, flat top, micro pullback, consecutive run), then a bare HOD break. A setup stays on the panel for about 25 seconds and refreshes while it keeps confirming.

    A few honest details:

    • Candle patterns need history. Bull flag, flat top, micro pullback and consecutive run read 1-minute candles that Scalpel builds from the live ticks once a stock is on the list. A name that joined two minutes ago cannot show a bull flag yet.
    • Gap and go and HOD break are regular hours only. The candle patterns can fire in the pre-market (guide 8.3).
    • Gap and go does not fire late. If a stock already crossed its pre-market high after the open before it reached the list, its gap and go has happened, and Scalpel will not call a later cross one.
    • The letters show on every panel, not just Setups, while a setup is live. Untick Setup chips in any scan's cog to hide them elsewhere; the Setups panel always shows them, because the setup is why the row is there.
    Note

    A setup chip is a pattern match, not a reason to buy on its own. Read the Level 2 and the tape before you press (guide 3.1). This style of trading is fast, difficult and carries a significant risk of loss.

    When each scan alerts

    A scan alerts with a toast, the bell sound and a voice callout only when its bell is on and a panel of that scan is open on a scan desk. A scan with no open panel stays silent however busy it is.

    Gap and go: JKLM +19%
    New momo: ABCD +11%
    New runner: TUVW +47%
    New on IBKR scanner: QRST +12%
    Scan toasts, top right: each names the scan or setup, the symbol and its change on the day. Click one to load the stock onto a desk. Demo data.
    • IBKR scanner and Running up alert the first time a stock appears on that scan in the session. A name that leaves and comes back does not alert again (unless you Clear the panel's log, which resets it).
    • High of day momentum and Setups alert on every fresh entry, at most once a minute per stock. On Setups the minute is per setup type, so a gap and go right after a micro pullback on the same stock still calls out.
    • The bell rings at most once every 1.5 seconds, so a burst of names at the open does not become a wall of noise. Every alert still lands in the panel's LOG view.

    The voice callout says the scan or setup name. To change sounds, see guide 10.1; for toasts, guide 10.2.

    What can go wrong

    • The IBKR scanner is full but Running up is empty. Its defaults are much stricter than the list: $2 to $20, under 10M shares out, 100K volume and a 2% burst in the last minute. On a slow tape that is rare. Loosen Min rel volume (x) or Min gap (%) in its cog.
    • Running up is always empty. Check Require news catalyst is off, or that intel is on.
    • No alert for a stock you saw appear. The bell is muted (a crossed-out bell on the panel title), no panel of that scan is open, or the stock already alerted on that scan this session.

    Questions

    Can I set filters for High of day momentum or Setups?
    No. They show every stock on the IBKR scanner's list that triggers. To narrow them, tighten the IBKR scanner's own filters in Settings > Connection.
    What is the difference between RVOL and Running up's relative volume?
    The RVOL column is today's volume against the 90-day daily average. Running up's Min rel volume is a burst: this second's volume against the average of the last 30 seconds.
    Why did gap and go not fire on a stock that gapped?
    Gap and go is the first cross above the pre-market high after 09:30, once a day. It does not fire if the stock had no pre-market trades, never crossed, or crossed before it joined the list.
    Do the setups work in the pre-market?
    Bull flag, flat top, micro pullback and consecutive run can fire from 04:00 ET once Scalpel has a few minutes of candles. Gap and go and HOD break wait for the open.
    Why does a stock show on High of day momentum and then vanish?
    It stays for 60 seconds after its latest new high. Without a fresh high in that minute it drops off, and the next break brings it back.
