Crypto Trading Dashboard



📘 Introduction – Why Build a Trading Dashboard?

Cryptocurrency trading has revolutionized the financial landscape, introducing decentralized assets and innovative trading mechanisms. As the crypto market operates 24/7, having a real-time dashboard becomes essential for traders to monitor price movements, analyze trends, and make informed decisions. 
  • By fetching and analyzing price data yourself, you’ll better understand market behavior.
  • Next.js is a modern framework that makes it easy to build and deploy fast, professional-grade web apps.
  • This guide includes not only code, but also troubleshooting tips and clear explanations for beginners.

By building a custom dashboard, you not only gain a deeper understanding of market dynamics but also hone your web development skills.

🧱 Main Content – Full Implementation Guide

 Chapter 1: Initial Setup

📦 1-1. Installing Next.js

Next.js is a powerful React framework that enables server-side rendering and static site generation, making it ideal for building high-performance web applications. To initiate your project, open your terminal and execute the following command:
npx create-next-app@latest crypto-dashboard

Use the following recommended options:

  • TypeScript: No (to keep the project simple)

  • ESLint: No (optional for this tutorial)

  • Tailwind CSS: No (we'll focus on functionality over styling)

  • src/ directory: No (default structure is sufficient)

  • App Router: Yes (leveraging Next.js 13+ features)

  • Turbopack: No (stick with the stable Webpack)

  • Import alias: No (default settings are adequate)

🖥️ 1-2. Run the development server

Navigate to your project directory and start the development server:
cd crypto-dashboard
npm run dev

Open your browser and visit http://localhost:3000 to see your Next.js application in action.

 Chapter 2: Creating the Trading Dashboard

📊 2-1. Key Trading Concepts

In trading, a time frame refers to the duration of time that a single candlestick represents on a chart. Common time frames include:
  • Time Frame: The duration of each candlestick (e.g. 1m, 5m, 1h, 1d)
  • Moving Average (MA): The average of closing prices over a specific number of candles
  • Volume: The total amount traded in that time period
Candlestick charts provide visual insights into price movements, displaying open, high, low, and close prices within each time frame.

2.2 Moving Averages (MA)

A Moving Average (MA) smooths out price data by creating a constantly updated average price. It's instrumental in identifying trends over specific periods. For instance, a 20-period MA calculates the average of the last 20 closing prices, helping traders discern the market's direction.

2.3 Volume Analysis

Volume indicates the number of units traded during a specific time frame. Analyzing volume alongside price movements can validate trends and signal potential reversals.

 Chapter 3: Deploying and Debugging

3.1 Fetching Data from Binance API

Binance offers a comprehensive API that provides real-time market data. We'll utilize the Kline (candlestick) endpoint to retrieve historical price data.

In your app/page.js file, implement the following code:

'use client'
import { useEffect, useState } from "react";

export default function Home() {
  const SYMBOL = "BTCUSDT";
  const INTERVAL = "1m";
  const MA_PERIOD = 20;
  const REFRESH_INTERVAL = 3000;

  const [price, setPrice] = useState(0);
  const [volume, setVolume] = useState(0);
  const [history, setHistory] = useState([]);

  useEffect(() => {
    const fetchData = async () => {
      const res = await fetch(
        `https://api.binance.com/api/v3/klines?symbol=${SYMBOL}&interval=${INTERVAL}&limit=${MA_PERIOD}`
      );
      const data = await res.json();
      const closePrices = data.map(d => parseFloat(d[4]));
      const volumes = data.map(d => parseFloat(d[5]));

      setPrice(closePrices[closePrices.length - 1]);
      setVolume(volumes[volumes.length - 1]);
      setHistory(closePrices);
    };

    fetchData();
    const interval = setInterval(fetchData, REFRESH_INTERVAL);
    return () => clearInterval(interval);
  }, []);

  const ma = history.length ? history.reduce((a, b) => a + b, 0) / history.length : 0;
  const gap = price - ma;

  return (
    <div>
      <h2>BTC Dashboard</h2>
      <p>Price: {price.toFixed(2)}</p>
      <p>MA20: {ma.toFixed(2)}</p>
      <p>Gap: {gap.toFixed(2)}</p>
      <p>Volume: {volume.toFixed(2)}</p>
    </div>
  );
}

3.2 Explaining the Code

  • SYMBOL: Specifies the trading pair (e.g., BTCUSDT).

  • INTERVAL: Defines the time frame for candlesticks.

  • MA_PERIOD: Number of periods for calculating the moving average.

  • REFRESH_INTERVAL: Time interval (in milliseconds) for refreshing data.

The useEffect hook fetches data from the Binance API at regular intervals, updating the state variables accordingly. The moving average is calculated by summing the closing prices and dividing by the number of periods.


🌐 Deploy to Vercel

  1. Push your code to GitHub
  2. Go to Vercel and import your GitHub repo
  3. In settings, set Root Directory to alphahunt-next
  4. Click Redeploy

🐞 Error Solved: Vercel 404

Problem: 404 error after deployment
Cause: Vercel was pointing to the wrong root folder
Fix: Set root directory to alphahunt-next and redeploy


 Chapter 4: Enhancing the User Interface

4.1 Structuring the Dashboard

To improve readability and user experience, consider organizing the data into distinct cards or sections:

  • Current Price: Displays the latest price of the selected cryptocurrency.

  • Moving Average (MA20): Shows the 20-period moving average.

  • Price Gap: Indicates the difference between the current price and the moving average.

  • Volume: Presents the trading volume of the latest period.

4.2 Styling Tips

While this tutorial focuses on functionality, enhancing the visual appeal can significantly improve user engagement. Consider using CSS frameworks like Tailwind CSS or styled-components to create a responsive and aesthetically pleasing dashboard.



 Chapter 5: Deploying Your Dashboard with Vercel

5.1 Preparing for Deployment

Before deploying, ensure your project is version-controlled using Git. Initialize a Git repository and commit your changes:

git init

git add .

git commit -m "Initial commit"


Push your project to a GitHub repository:

git remote add origin https://github.com/yourusername/crypto-dashboard.git

git push -u origin main

5.2 Deploying to Vercel

Vercel offers seamless integration with GitHub for deploying Next.js applications:

  1. Visit Vercel and sign in with your GitHub account.

  2. Import your crypto-dashboard repository.

  3. During the setup, ensure the Root Directory is set to crypto-dashboard if your project is nested.

  4. Click Deploy and wait for the deployment process to complete.

Once deployed, Vercel will provide a live URL where your dashboard is accessible.


Chapter 6: Troubleshooting Common Issues

6.1 Vercel Deployment Errors

If you encounter a 404 error after deployment, verify the Root Directory setting in Vercel's project configuration. It should point to the correct folder containing your Next.js project files.

6.2 API Rate Limits

The Binance API has rate limits to prevent abuse. If you receive rate limit errors, consider implementing exponential backoff strategies or caching mechanisms to reduce the frequency of API calls.
