What it draws
The Curve draws a single smooth bend between two endpoints, shaped by a control point you position after placing the ends. It behaves like a flexible line you can bow toward or away from price.
How to draw it
- Pick Curve from the left toolbar (Shapes group).
- Click to place the first endpoint, click again for the second, then move the pointer to bend the curve and click once more to lock in its shape. Drag the control handle later to re-bend it.
How traders use it
- Draw a curved support line under a parabolic advance where straight trendlines keep breaking.
- Show the accelerating slope of a blow-off move to argue that the pace is unsustainable.
- Connect a series of rounding swing lows more faithfully than a straight trendline would.
Settings reference
Double-click the drawing (or use its floating toolbar → gear) to open settings:
| Setting | Control | Possible values | Default | Effect |
|---|---|---|---|---|
| Extend | multi-select | Extend left line | Extend right line (dropdown summarizes as Don't extend / Extend left line / Extend right line / Extend both) | Don't extend | Extends the line past its anchor points to the left and/or right edge of the chart. |
| Color | color | any color (theme color picker) | #05B878 | Main stroke color of the drawing — lines, outlines and (unless overridden) labels derive from it. |
| Line Width | select | 1px | 2px | 3px | 4px | 2px | Stroke thickness of the drawing’s lines and outlines. |
| Line Style | select | Solid | Dashed | Dotted | Solid | Dash pattern used for the drawing’s lines. |
| Fill Background | checkbox | on/off | off | Fills the area enclosed by the curve. |
| Background Color | color | any color | same as line color | Fill color used when Fill Background is on. |
| Opacity | slider | 0–100 | 20 | Opacity of the curve’s background fill. |
| [Tab] Text — Text | checkbox + textarea | on/off, with a multiline text box for the label content | off (on when the drawing already carries text) | Enables an attached text label on the drawing; typing in the box auto-enables it and updates the label live. |
| [Tab] Text — Text Color | color | any color | same as the drawing’s line color | Color of the attached text label. |
| [Tab] Text — Font Size | select | 8, 10, 11, 12, 14, 16, 18, 20, 24, 28, 32, 36, 48, 64, 72 | 14 | Point size of the attached label text. |
| [Tab] Text — Bold | checkbox | on/off (B toggle button) | off | Renders the label in bold. |
| [Tab] Text — Italic | checkbox | on/off (I toggle button) | off | Renders the label in italics. |

| [Tab] Text — Text alignment (horizontal) | select | Left | Center | Right | Center | Horizontal placement of the label relative to the drawing. |
| [Tab] Coordinates | number + datetime | one row per anchor point: price (number, step 0.05) and local date/time | the drawing’s current anchor values | Edits anchor geometry numerically — changing a point’s price or time moves the drawing live on the chart. |
| [Tab] Visibility | checkbox + number range | interval buckets: Ticks; Seconds 1–59; Minutes 1–59; Hours 1–24; Days 1–366; Weeks 1–52; Months 1–12; Ranges (each bucket has an on/off checkbox, most also a from–to range) | visible on all intervals | Per-timeframe visibility rules — untick a bucket to hide the drawing on those chart resolutions, or narrow the from–to range within a bucket. |
Editing & managing
- Move / adjust: drag the drawing or any anchor handle; magnet mode snaps points to OHLC values.
- Clone / lock / hide / delete from the floating toolbar or right-click menu.
- Templates: save the current style from the settings dialog and reapply it to new drawings.
- Every action is undoable (⌘Z / Ctrl+Z).
Watch out for
- A curve can be bent to fit almost any price action after the fact, so be honest about whether the market actually followed it or you shaped it to the outcome.
