✨ Why Exeria Charts?

Building a trading interface shouldn't require compromising on performance or user experience. Exeria Charts gives you the power of professional-grade financial charts, directly inside your application.

• ⚡️ Native Integration: Render directly inside your app (Canvas/WebGL) instead of relying on sluggish <iframe> embeds.
• 📊 Versatile Views: Ship candlestick, line, bar, and histogram views using a single, unified runtime.
• ⏱ Real-time Ready: Seamlessly update charts with historical candle batches or stream real-time ticks with sub-millisecond latency.
• 🎨 Fully Customizable: Layer drawing tools, technical indicators, and UI controls perfectly themed to match your product shell.
• 🔒 Self-Hosted & Secure: Keep your users' data secure by hosting the runtime entirely within your own infrastructure.

📦 Ecosystem

Exeria provides a robust ecosystem tailored to both framework-agnostic developers and React teams.

const interval: Interval = { symbol: "1h", milis: 60 * 60 * 1000 };

// 2. Initialize the chart
const container = document.getElementById("chart-root");
if (!container) throw new Error("Missing chart container");

const chart = createChart({ container });

// 3. Mount and render
await chart.setMainSeriesData(candles, interval);
