Zoom In

The zoom-in tool magnifies the chart, reducing the visible time range and expanding price detail. It is essential for analyzing tight price action, identifying micro-structures, placing precision drawings, and examining individual candles in detail.

Zoom in can be triggered in several ways, each suited to different workflows. Rectangle zoom gives you precise control over the exact region to magnify. Scroll-wheel zoom provides smooth, continuous zooming centered on the cursor position. Keyboard zoom applies fixed-step increments centered on the current view.

• Rectangle zoom — drag a rectangle around the target area; the chart zooms to fit that rectangle exactly.
• Scroll-wheel zoom — scroll up to zoom in at the cursor position; the chart re-centers on the cursor location.
• Keyboard zoom — press the + or = key to zoom in a fixed step centered on the current view.
• Pinch zoom (touch) — on touch devices, pinch outward to zoom in at the gesture center.

Rectangle zoom is the most precise zoom method. Select the zoom-in tool, then click and drag on the chart to define a rectangular region. As you drag, a preview rectangle shows the area that will be magnified. When you release the mouse, the chart zooms to fill the viewport with that region. The aspect ratio of the rectangle is preserved, so the zoomed view matches the shape of your selection.

Hold Shift while dragging to constrain the rectangle to a perfect square. Hold Alt/Option to draw the rectangle from its center outward rather than from a corner. These modifiers give you finer control over the selection geometry.

Scrolling the mouse wheel up zooms in centered on the cursor position. This means you can zoom into a specific area without first dragging a rectangle — just position the cursor where you want to magnify and scroll. Each scroll notch applies approximately a 1.2x zoom factor, and the zooming is animated smoothly.

The zoom center is the cursor position at the start of the scroll. If you move the cursor while scrolling, the zoom center updates continuously, letting you "follow" price action as you zoom in. This makes scroll-wheel zoom the fastest method for exploratory analysis.

1. 1
   Rectangle zoom

   Select the zoom-in tool, click and drag to define a rectangle. Release to zoom into that region.
2. 2
   Scroll-wheel zoom

   Position the cursor where you want to center the zoom, then scroll up.
3. 3
   Keyboard zoom

   Press the + or = key to zoom in incrementally. The view centers on the current chart position.
4. 4
   Touch zoom

   On touch-enabled devices, pinch outward with two fingers to zoom in.

   Return to previous view

   Press Ctrl/Cmd + Z (undo zoom) or use the chart history to go back to the previous zoom level.

Every zoom action is recorded in a zoom history stack. You can navigate backward and forward through this history using Ctrl/Cmd + Z (undo zoom) and Ctrl/Cmd + Y (redo zoom). The history stack persists as long as the chart is open, letting you freely explore zoom levels without losing track of your starting view.

The chart automatically loads the appropriate data granularity for the current zoom level. When zoomed in to a 5-minute view, the chart loads 1-minute or tick data. When zoomed out, it loads higher-level aggregated data. This automatic data loading ensures optimal performance while providing the most detailed view available for your selected zoom level.

When animated zoom is enabled, the zoom transition uses an ease-in-out curve that accelerates at the start and decelerates at the end. This creates a smooth, professional feel. The animation duration is approximately 200ms for keyboard zoom and 150ms for scroll-wheel zoom. Rectangle zoom uses a 250ms animation. These durations can be adjusted in the advanced zoom settings for users who prefer faster or slower transitions.

Double-clicking the zoom-in tool resets the zoom to the default view (typically showing the most recent 6-12 months of data, depending on the instrument). This serves as a "home" button that returns you to a standard overview from any zoom level. The home view level is configurable in the settings, allowing you to define exactly what zoom level constitutes your baseline view.

When zooming in on very long timeframes (weekly, monthly), the chart automatically switches to intraday data at certain zoom thresholds. For example, zooming in on a daily chart past a certain point switches to hourly data, then to 15-minute data. This automatic resolution switching ensures you always see the most detailed data available for the current zoom level without manually changing timeframes.
