Candlestick Chart

Candlestick charts are the foundation of technical analysis. In Cluster Terminal, the candlestick mode renders standard Japanese candlesticks from Binance Futures & Spot OHLC data with full control over colors, borders, shadows, body opacity, corner rounding, and glow effects.

​

What Candlestick Charts Show

Each candlestick represents price action over a single time period (determined by your selected timeframe). A candle encodes four data points: The rectangular body of the candle spans from the open to the close. The thin lines extending above and below the body are called shadows (or wicks), and they represent the high and low of the period.

• A bullish candle (close > open) indicates that price moved up during the period. By default, bullish candles are colored green.
• A bearish candle (close < open) indicates that price moved down during the period. By default, bearish candles are colored red.

When the open and close are equal (or nearly equal), the candle appears as a thin horizontal line called a doji, signaling indecision between buyers and sellers.

​

Timeframe Selection

The timeframe determines the duration each candle represents. Cluster Terminal supports the following timeframes: Select the timeframe from the dropdown in the chart toolbar. Changing the timeframe reloads the candle data from the server and re-renders the chart.

​

Body Colors

Cluster Terminal uses separate color settings for bullish and bearish candle bodies. You can customize these in Appearance > Color Overrides or through the chart settings panel.

​

Bullish (Up) Body Color

The fill color for candles where close is greater than or equal to open. The default is a green shade optimized for dark themes.

​

Bearish (Down) Body Color

The fill color for candles where close is less than open. The default is a red shade that provides clear contrast against the bullish color on any theme.

​

Body Opacity

The bodyOpacity setting controls the transparency of the candle body fill. The default value is 0.88 (88% opaque), which provides a slightly translucent appearance. Reduce opacity if you want indicators or overlays behind the candles to show through.

​

Borders and Outlines

Each candle body can display a distinct border (outline) with independent color control.

​

Border Width

The borderWidth setting controls the thickness of the candle body outline in pixels. The default is 1px. Set to 0 to disable borders entirely and show only filled bodies.

​

Border Colors

Border colors are configured separately for bullish and bearish candles:

• Up Border (candleUpBorder) — the outline color for bullish candles. If not set, it defaults to a slightly darker shade of the up body color.
• Down Border (candleDownBorder) — the outline color for bearish candles. If not set, it defaults to a slightly darker shade of the down body color.

​

Shadows (Wicks)

Shadows extend vertically from the candle body to the high and low prices. Their color is configurable independently from the body and border.

​

Shadow Colors

• Up Shadow (candleUpShadow) — the wick color for bullish candles.
• Down Shadow (candleDownShadow) — the wick color for bearish candles.

By default, shadow colors match the body colors. Some traders prefer muted or gray wicks to keep focus on the body itself. Others set all wick colors to a single neutral color regardless of candle direction.

​

Corner Radius

The cornerRadius setting rounds the corners of the candle body. The default is 1 (minimal rounding). Increase this value for a softer, more modern appearance. Set to 0 for perfectly sharp rectangular candles.

​

Glow Effect

The glowIntensity setting adds a luminous glow around candle bodies. The default value is 0.28 (subtle glow). This effect uses the body color to generate a soft halo, making candles stand out against the background.

When to Use Candlestick Mode

Candlestick mode is the lightest rendering mode in Cluster Terminal. It does not load or render volume cluster data, which makes it ideal for several scenarios:

​

Higher Timeframe Overview

Use candlestick mode on 4h or 1d charts to identify the broader trend and key price structure. Cluster data is less actionable at these timeframes because the volume is aggregated over very long periods.

​

Multi-Chart Layouts

When running four or more charts simultaneously, switching some panes to candlestick mode reduces GPU and memory usage significantly. Each cluster chart requires rendering hundreds or thousands of individual cells; a candlestick chart renders only the candle bodies and wicks.

​

Pattern-Based Analysis

If your trading methodology focuses on candlestick patterns (engulfing, doji, hammer, pin bar) or classical chart patterns (head and shoulders, triangles, wedges), candlestick mode provides a clean, uncluttered view.
