    Guides/4. Placing trades

    Guide 4.6

    The order bar and orders panel

    Beginner, 6 min read. Checked with Scalpel 1.12.8 on October 15, 2026.

    In short

    The order bar sits under each desk's chart: a Buy row with the sizing method dropdown, your four buy buttons (each with the dollar size it would buy above it) and the buy Offset, and a Sell row with Full, 1/2, 1/4, 1/2 Ask, 1/2 Mid, B/E, Trail, Cancel and the sell Offset. Below it, the ORDERS & POSITIONS panel has a Positions tab (open position over closed trades, with fees and R) and an Orders tab, plus a NET P&L for the desk's symbol.

    Everything on the order bar has a hotkey (guide 4.3), and most traders end up using the keys. The bar is still worth knowing: its size lines tell you what a key will buy before you press it, and its steppers are the fastest way to change an offset or the Risk (Cents) stop mid-session.

    The order bar, control by control

    The order bar with a position open. 1 Method dropdown, 2 buy buttons with their size lines, 3 buy Offset, 4 sell buttons, 5 B/E, Trail and Cancel, 6 sell Offset. Demo data.
    ControlWhat it doesKey
    Method dropdownShows the first preset's sizing kind; picking a kind switches all four presets to it (guide 4.1)
    Buy buttonsBuy with preset 1 to 4. The label is the preset: 100 sh, $2500, Risk $50Shift+1 to 4
    Size line (above each buy)The dollar size that press would put on at the current ask: $571, $1.9k. A dash means no ask yet or zero shares
    Stop stepperOnly with Risk (Cents) as the method. The cents stop the risk buttons size against, 5c a click, never under 1c. It changes the saved setting for every desk (guide 4.2)
    Offset (buy row)How far above the ask a buy may fill, 10c a click, never under 0
    Full, 1/2, 1/4Sell all, half or a quarter at the bid minus the sell offsetCtrl+Z, X, C
    1/2 Ask, 1/2 MidOffer half at the ask or the midpointCtrl+A, S
    B/EMove the working stop up to your entry (a stop already above it stays put)B
    TrailTurn trailing on or off; the button is lit while trailingShift+T
    CancelCancel working orders on this symbol; only shown while you hold a positionCtrl+Q
    Offset (sell row)How far under the bid a bid exit may fill, 10c a click

    Clicking any button also focuses that desk, so the next hotkey goes to it.

    When buttons are grey

    • No symbol on the desk: everything is grey.
    • No position: the Sell row, B/E and Trail are grey and Cancel is hidden.
    • Stock halted: the buy buttons are grey until the halt lifts (guide 4.4).
    • Market closed (before 04:00 or after 20:00 ET, weekends and holidays): every button is grey. The B, Shift+T and Ctrl+Q keys and the header's Flatten All still work. See guide 13.13.

    To hide the bar, open the chart pane's settings (the gear on CHART) and untick Quick-order buttons. The hotkeys keep working without it.

    Careful

    The steppers are not per-trade or per-desk. Every Offset and Stop click changes the saved value, for every desk, until you change it again, the same as editing Settings > Trading or Settings > Stops.

    The orders and positions panel

    Each desk's ORDERS & POSITIONS panel shows only that desk's symbol, in the mode you are in (SIM and LIVE keep separate positions, orders and history). Two tabs:

    Positions

    OPEN (your position) above CLOSED (finished trades on this symbol, newest first).

    ColumnOpen rowClosed row
    1SYMBOLTIME the trade closed

    4NOTIONAL: shares x last priceEXIT price
    5FEE: commission so farFEE: entry and exit commissions
    6UNREAL (R): open P&L and RNET (R): P&L after fees, and R

    The open row is washed green or red, stronger the more R it is up or down. NET P&L at the top right adds this symbol's closed trades in the list to the open P&L.

    The Positions tab: 400 ABCD open at +1.7R, a +1.0R winner and a -1.2R loser closed. Demo data.

    To read returns as a percent of entry instead of R, set Settings > Appearance > Stops / TP returns to Percent (%); the headings change to UNREAL (%) and NET (%) (guide 5.4).

    Orders

    Every order on the symbol, newest first: TIME, QTY, SIDE (BUY green, SELL red), FILL (the average fill price), FEE and STATUS: Pending, Working, Partial, Filled, Cancelling, Cancelled or Rejected. Filled reads in plain text, Rejected in red, and every other status in amber.

    The Orders tab with a buy still working as Partial. Demo data.

    The TIME columns are New York time, the same clock as the header, so 09:41 is eleven minutes after the open whatever time zone your computer is in.

    A fee of - means none has been booked yet. In LIVE the commission is the broker's real figure and can arrive a moment after the fill; in SIM it is the estimate for your commission plan (guide 6.3). The full history and stats are in Analytics (guide 6.4).

    Questions

    What does the number above each buy button mean?
    The dollar size that press would buy at the current ask, worked out exactly as the order will be. $1.9k over Risk $100 means about $1,900 of stock.
    Why is the order bar greyed out?
    There is no symbol on the desk, the market is closed (outside 04:00 to 20:00 ET or a weekend or holiday), the stock is halted (buys only), or, for the sell row, you hold no position.
    Where do I see my fees?
    In the FEE column of the Positions and Orders tabs. Closed trades show the entry and exit commissions together, and NET is after fees.
    Why does the Cancel button disappear?
    It only shows while you hold a position on that desk. Ctrl+Q cancels working orders whether or not it is showing.
    Can I hide the order bar?
    Yes: untick Quick-order buttons in the chart pane's settings. The hotkeys still work.
