How to Build a Professional Trading Website with Next.js in 2025

From live Binance charts to authentication and product marketplace — a complete guide to building a modern trading platform with Next.js 14, Supabase and Three.js.

Why Traders Need Custom Websites in 2025

A personal trading website is no longer optional if you're serious about:

  • Selling EAs and indicators
  • Attracting prop firm clients
  • Building a trading community
  • Showcasing your track record

Generic solutions (Gumroad, Linktree) look amateur. A custom Next.js site screams professional.


The Stack I Use for Every Trading Project

**** Frontend: Next.js 14 + TypeScript + Tailwind CSS 3D/Anim: React Three Fiber + Framer Motion Charts: lightweight-charts (TradingView library) Data: Binance WebSocket API (free, no key needed) Backend: Supabase (DB + Auth + Storage) Deploy: Vercel (free tier) ****


Building the Live Chart Component

The most impressive part — a real-time MT5-style chart:

****`typescript
import { createChart, ColorType } from 'lightweight-charts';
import { useEffect, useRef } from 'react';

export function LiveChart() {
const containerRef = useRef(null);

useEffect(() => {
const chart = createChart(containerRef.current!, {
layout: {
background: { type: ColorType.Solid, color: 'transparent' },
textColor: '#9ca3af',
},
grid: {
vertLines: { color: 'rgba(255,255,255,0.04)' },
horzLines: { color: 'rgba(255,255,255,0.04)' },
},
});

const series = chart.addCandlestickSeries({
  upColor: '#26a69a',
  downColor: '#ef5350',
});

// Connect Binance WebSocket
const ws = new WebSocket('wss://stream.binance.com:9443/ws/btcusdt@kline_15m');
ws.onmessage = (event) => {
  const { k } = JSON.parse(event.data);
  series.update({
    time: k.t / 1000,
    open: parseFloat(k.o),
    high: parseFloat(k.h),
    low: parseFloat(k.l),
    close: parseFloat(k.c),
  });
};

return () => { ws.close(); chart.remove(); };

}, []);

return

;
}
****`


Connecting the Product Marketplace to Supabase

****typescript // lib/db/products.ts export async function getProducts() { const supabase = createSupabaseServerClient(); const { data } = await supabase .from('products') .select('*') .eq('is_active', true) .order('sort_order'); return data ?? STATIC_FALLBACK; } ****

Admin can add/edit products from a protected dashboard — no code needed after setup.


SEO for Trading Websites

The keywords that bring real clients:

  • "Expert Advisor developer", "MQL5 freelancer"
  • "Pine Script indicator custom"
  • "prop firm EA", "FTMO challenge robot"

Add JSON-LD structured data for maximum Google visibility:

****json { "@type": "ProfessionalService", "name": "Your Trading Services", "hasOfferCatalog": { "itemListElement": [ { "name": "Expert Advisor Development" }, { "name": "Prop Firm Challenge Passing" } ] } } ****
