    Guides/5. Stops and targets

    Guide 5.2

    Move your stop and target on the chart

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

    In short

    To move your stop or target, grab the red stop line or the green take-profit line on the chart (or its price tag on the right-hand axis) and drag it: the line, its P&L chip and its tag follow the mouse, and the new level takes effect when you let go. With no target set, drag the green + TP handle on the entry line up to add one. Double-click a line to put it back to its default. The stop stays at least one tick under the last price and within 8R of your entry; the target within 8R above entry, and dragging it down through entry removes it.

    Your stop and target are levels Scalpel watches (guide 5.1), so moving them is instant: there is no order at the broker to modify or cancel. Dragging is the quickest way to put the stop under a level that matters on the chart, or to push the target up to the next resistance.

    Before you start

    • A position open on the desk, with its stop and target armed (guide 4.4).
    • The chart on a timeframe where you can see the levels, usually 10s or 1m (guide 3.5).

    Before: 400 ABCD at 5.50, the stop at 5.38 (-1.0R) and the target at 5.74 (+2.0R). Demo data.

    Move a level

    1. 01

      Point at the line or its price tag

      Hover the red stop line or the green take-profit line until the cursor turns into an up-and-down arrow. You can grab anywhere within a few pixels of the line, or on its coloured price tag on the right-hand axis, which is easier on a busy chart. If the two lines are close, the take-profit wins.

    2. 02

      Drag it to the new price

      Hold the mouse button and drag. The line, its chip and its price tag move with the cursor and snap to the stock's tick (1c on most stocks). The chip shows what the level would realise at each price, in dollars and R, so you can see the new risk before you commit.

    3. 03

      Let go to commit

      Release the button. The level is live from that moment, in the mode you are trading (SIM or LIVE). The keyboard goes back to the cockpit, so your hotkeys work straight away.

      CHART
      10s1m5m1h1d
      Above VWAP, EMAs upBroke the range high
      ABCD4.895.095.305.505.715.70+80.00 (+1.7R)-72.00 (-1.5R)5.32+96.00 (+2.0R)5.74
      The stop dragged from 5.38 down to 5.32: the chip reads -72.00 (-1.5R). R stays the 12c you entered with, so a wider stop shows as more than 1R. Demo data.

    When you move the working stop, the catastrophe net (the hidden backstop under it) moves by the same amount, so it stays the same distance below.

    CHART
    10s1m5m1h1d
    Above VWAP, EMAs upBroke the range high
    ABCD4.895.135.365.595.825.70+80.00 (+1.7R)-48.00 (-1.0R)5.38+144.00 (+3.0R)5.86
    The take-profit dragged up from 5.74 to 5.86: +144.00 (+3.0R). Demo data.

    Add a target with + TP

    If a position has no take-profit (you set Take profit (R) to 0, or dragged the target away), a small green + TP handle sits just above the entry line at the right edge of the chart. Drag it up and let go: that price becomes your target.

    CHART
    10s1m5m1h1d
    Above VWAP, EMAs upBroke the range high
    ABCD4.895.095.285.485.675.70+80.00 (+1.7R)-48.00 (-1.0R)5.38+ TP
    1
    No target: the + TP handle 1 sits on the entry line. Drag it up to add a take-profit. Demo data.

    Remove the target

    Drag the take-profit down to your entry or below and let go: the target is cleared and the + TP handle comes back. The position then exits only on a stop, a manual sell or a flatten.

    Reset with a double-click

    Double-click a line (two clicks within about a third of a second) to put it back to its default:

    • Stop: one R under your entry, the distance you entered with (or a tick under the last price, if price is already below that). The catastrophe net moves with it.
    • Take-profit: Take profit (R) times R above entry (2R by default). With Take profit (R) at 0, a double-click removes it.

    The limits

    LevelCan goCannot go
    Working stopAnywhere from 1 tick under the last price down to 8R under entryAt or above the last price (it would fire at once); further than 8R down
    Take-profitFrom 1 tick above entry up to 8R above entryFurther than 8R up (it stops there); at or below entry clears it

    With a 12c stop on a 5.50 entry and the last trade at 5.70, the stop can go from 5.69 down to 4.54, and the target from 5.51 up to 6.46. The limits stop a slip of the mouse from parking a line somewhere absurd, or through the market. A line pulled off the chart is pinned to the edge so you can always grab it back; right-click the price axis to return it to auto-fit.

    You can drag a stop into profit. While price is above your entry, a stop can sit at or above the entry, to lock in a gain. A stop that B (breakeven) or trailing has already lifted stays where it is when you grab it; it is only ever held under the last price. Dragging works both ways, though: you can also pull a stop back down, so watch the chip before you let go.

    Note

    R on the chip and the 8R limits use the risk Scalpel recorded when the position opened, in SIM and LIVE alike. A LIVE position Scalpel adopted from TWS uses its default stop distance as R.

    Tips

    • Put the stop under a level, not on it. A cent or two under a round number or a candle low is less likely to be tagged by a wick than the level itself.
    • Watch the R on the chip as you drag. If widening the stop takes it to -2R, your loss at the stop is twice what you planned. Consider selling some shares instead.
    • Drag the target before the move, not during it. A target you keep pushing up is no longer a plan.

    More on the reasoning in the blog post Stops that live in the app.

    Questions

    How do I move my stop loss on the chart?
    Grab the red stop line, or its price tag on the right axis, drag it to the new price and let go. The stop moves the moment you release.
    How do I add a take profit after entering?
    Drag the green + TP handle on the entry line upward and release at your target price. It shows whenever a position has no target.
    Can I drag my stop above my entry?
    Yes, while price is above your entry. A dragged stop is only held at least one tick under the last price, so it can lock in a gain. B and trailing do the same by key or automatically.
    How do I remove the take profit?
    Drag the green line down to or below your entry and let go, or set Take profit (R) to 0 in Settings > Stops for future trades.
    Does dragging the stop send anything to my broker?
    No. Stops and targets are watched by Scalpel, so a drag just changes the level it watches. The exit order is only sent when price trades through it.
