    Guide 10.2

    Alerts and toasts

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

    In short

    Toasts are the short messages that stack at the bottom centre of Scalpel's window. The edge colour says how much it matters: blue is information, green is good news, amber is a warning and red means an order was refused, a stop fired or something needs you now. Each toast clears after 7 seconds or when you click it, and a toast about a stock reads click to load: clicking it puts that symbol on a desk.

    Scalpel tells you what happened in three places at once: a toast on screen, a callout in your ear (guide 10.1) and the orders panel. The toast carries the detail the voice leaves out, such as which cap blocked an order or what a filing was. This page lists every toast Scalpel shows, word for word, and what to do about each.

    How toasts work

    • Where: at the bottom centre of the window, newest at the bottom. At most five show at once.
    • How long: 7 seconds each. Click a toast to dismiss it early.
    • Colour and icon: blue or green with an eye icon for information; amber or red with a warning triangle for problems.
    • Click to load: a toast about a particular stock shows a pointer and Click to load. Clicking it focuses the desk already showing that symbol; otherwise it loads the symbol on an empty trader desk, then on a trader desk with no position. A desk holding a position is never changed. If every trader desk holds a position you get No free desk: every trader desk holds a position; if every desk is a scan desk, No trader desk open: click SCAN on a desk to switch it to TRADER.
    ABCD take profit hitClick to load
    SIM mode activated
    IB connection lost
    Order exceeds the fat-finger cap ($250000)
    The four kinds: green success, blue info, amber warning and red danger. The take-profit toast is about a stock, so it can be clicked to load ABCD. Demo data.

    Orders and positions

    ToastColourWhat it means and what to do
    Order exceeds the fat-finger cap ($250000)RedOne order was bigger than your fat-finger cap ($250,000 by default). Use a smaller preset or lower the cap to fit your account (guide 7.2)
    Position would exceed the max ($250000)RedThe buy would take this symbol past your max-position cap
    Insufficient buying power: order $8000 exceeds free cash $5000RedSIM is a cash account and the order does not fit in your free cash (guide 6.1)
    Risk locked: Daily loss limit hit (-$1000)RedYou pressed a buy while the daily loss limit is tripped: new entries are blocked until you click Resume trading or a new day starts (guide 7.1)
    Order size resolves to zero sharesRedThe preset worked out to under one share, usually a tiny risk with a wide stop
    ABCD is halted: buys are blocked until it resumesRedThe stock is halted and reopens with an auction gap, so no entry may queue for it. Exits still work
    No liquidity for ABCDRedSIM found nothing offered at or under your limit
    No symbol loaded, No market data yet, No ask to price against, No book to price the exitRedThe desk has no symbol, or no book to price the order from. Wait for Level 2 or check the desk's badges (guide 2.5)
    No long position to sellRedYou pressed a sell with no position on this symbol. Scalpel is long only and never sells short
    ABCD: no shares to sellRedLIVE: Interactive Brokers shows no shares of this stock to sell, so the sell was not sent
    ABCD rejected: ... with IBKR's reason and codeRedLIVE: Interactive Brokers refused the order (guide 13.5)
    ABCD: no acknowledgement from the order manager; order not placedRedLIVE: TWS never confirmed the order, so Scalpel treats it as not placed. Check TWS and your connection
    ABCD: exit still not filled after 5 re-prices. Check it in TWSRedLIVE: a stop, target or catastrophe exit was re-priced under the latest price 5 times and is still open. It stays working: check it in TWS, or press Flatten All (guide 5.1)
    Market closed - orders disabledAmberYou pressed a buy or sell key while the session is closed (before 04:00 or after 20:00 ET, weekends, holidays) (guide 13.13)
    D1 holds a position: close it before changing the symbolRedA desk with an open position keeps its symbol
    D1 holds a position: close it before switching it to SCANRedA desk with an open position stays a trader desk, so its stop keeps being watched
    Flatten all sentAmberFlatten All or Esc sent an exit for every position. A sell already working is replaced, never stacked
    Flatten all sent. The market is closed: IBKR may hold the sells until pre-market opens at 4:00 ETAmberLIVE, with the market closed: the exits are sent anyway and can fill from 04:00 ET
    Flatten all sent. The market is closed: SIM fills at the last prices it sawBlueSIM, with the market closed
    ABCD stopped out (working stop) or (catastrophe stop)RedA stop fired and closed the position (guide 5.1)
    ABCD take profit hitGreenThe take-profit closed the position
    ABCD: position held but on no desk, so its stop is not watched. Load it on a desk.AmberLoad the symbol on a desk, or its stop does nothing. Repeats every 5 minutes until you do

    Exit warnings

    ToastColourWhat it means
    ABCD: bull trap, tends to dip in the next minuteAmberYour long's 1-minute chart poked above the recent high and closed back under it
    ABCD: thin bid side, exit carefullyRedSelling your whole position into the bids on screen would slip 0.6% or more. Scale out instead of dumping

    Both come with a voice warning and can be switched off in the Level 2 panel's cog (guide 10.1).

    Intel alerts

    ToastColourWhat it means
    EFGH filed 424B5: ATM or takedown prospectusRed if you hold it, amber if you are only watchingA financing filing: the company can sell stock into the move. On a held symbol you also hear the exit warning (guide 9.2)

    ABCD FDA: ABCD receives FDA clearanceClick to load
    Intel toasts: a red financing filing on a held symbol, an amber offering headline on a watched one, a blue strong catalyst. Demo data with fictional headlines.

    Scanner alerts

    A blue toast for every new name or setup a scan panel announces: New on IBKR scanner: PQRS +26%, New momo: PQRS +26%, New runner: ..., or the setup's name (Gap and go, Micro pullback, HOD break, Bull flag, Flat top, Consecutive run) followed by the symbol and its change. They only come from scan panels open on a desk with the scan's bell on, and every one can be clicked to load the symbol (guide 8.2).

    New momo: PQRS +26%Click to load
    PQRS: Offering headline. Press buy again to confirmClick to load
    A scanner alert and a held-back buy, both clickable. Demo data.

    Alerts that are not toasts

    Some things stay on screen until they are dealt with:

    • The RISK LOCK banner: a red bar under the header reading RISK LOCK - Daily loss limit hit (-$1000). New entries blocked. with Resume trading. It stays until you resume or switch mode (guide 7.1).
    • The connection banner under the header while TWS or IB Gateway is not connected, with buttons to switch port or start the program (guide 1.4).
    • Desk badges: DELAYED, NO DATA, STALE and the HALTED banner (guide 2.5).
    • Update ready in the status bar.

    Questions

    Where do toasts appear in Scalpel?
    At the bottom centre of the window, newest at the bottom, up to five at a time. Each clears after 7 seconds or when clicked.
    How do I load a stock from a toast?
    Click it. Toasts about a stock show Click to load. Scalpel focuses the desk already showing that symbol, or loads it on an empty trader desk, then on one with no position. A desk holding a position is never changed.
    Can I turn toasts off?
    Not as a group. You can turn off the noisy ones at their source: strong catalyst alerts in Settings > Intel, each scan's bell in its panel, and the two exit warnings in the Level 2 cog.
    What does a red toast mean?
    Something was refused or needs you now: an order rejected, a buy on a halted stock, a stop fired, an exit that would not fill, LIVE mode switched on, a thin bid exit warning, or a financing filing on a stock you hold.
    Why do I keep seeing position held but on no desk?
    You hold a position whose symbol is not loaded on any desk, so its stop has no price to watch. Load the symbol on a desk. It repeats every few minutes until you do.
