Here is an article that provides a solution for retrieving recent trade orders from Binance API via WebSocket streams in Node.js:

Retrieving Recent Trade Orders from Binance API via WebSocket streams in Node.js

In this article, we will explore how to retrieve recent trade orders using the Binance API and send them as WebSocket streams in Node.js.

Prerequisites

  • You have a Binance account and are authorized to use the API.

**You have installed the node-binance-api package: npm install node-binance-api

Setup

  • Create a new file in your project directory, e.g., binance-trade-orders.js.
  • Import the node-binance-api package and create an instance of the API class.

`javascript

const Binance = require('node-binance-api');

const api = new Binance({

// Your API credentials

clientId: 'your-client-id',

clientSecret: 'your-client-secret',

serverId: 'YOUR_SERVER_ID',

});

// Set WebSocket options

const wsOptions = {

server: 'ws://ws.binance.com/1/api/ws',

keepalive: true,

};

// Create a WebSocket object

const ws = api.ws(wsOptions);

// Define a function to handle incoming orders

Asynchronous function in tradeOrders() {

try {

// Send a getOrders command to get recent trades

const response = await ws.get('GETORDERS', { limit: 10, timeout: 1000 });

// Process the received data and store it in an array

const recentOrders = response.data;

console.log(recentOrders);

} catch (error) {

console.error(error);

}

}

// Call the tradeOrders function to get recent trades

tradeOrders();

`

How ​​it works

Ethereum: get recent trade orders info in web socket streams binance api(node js)

  • We create a new instance of theBinanceAPI class, passing in your API credentials and client ID.
  • We define a WebSocket object using thews()method, specifying the Binance API URL and WebSocket options (e.g. keepalive).
  • We define atradeOrders()function, which sends a getOrders command to get recent trades.
  • In the function, we use thews.get()method to send the request and get the response.
  • We process the received data, store it in an array, and log it to the console.

Note: This implementation uses thelimitparameter to retrieve 10 recent transactions at a time. You can adjust this value based on your performance needs.

By following these steps, you should be able to retrieve recent transaction orders via WebSocket streams from the Binance API in Node.js using thenode-binance-api` package.

Safe Ways to Withdraw Large Amounts of Crypto

As the cryptocurrency market continues to grow and evolve, many users are wondering how to safely withdraw large amounts of their digital assets. Thanks to the rise of decentralized finance (DeFi) and online exchanges, it is now easier than ever for users to access their cryptocurrencies from anywhere in the world. However, this increased accessibility also comes with a higher risk of security breaches, hacking, and other illegal activities.

In this article, we will look at the safest ways to withdraw large amounts of cryptocurrency and provide tips on how to protect your assets and prevent potential losses.

Why Large Payments Can Be Risky

The Safe Way to Withdraw Large Amounts of Cryptocurrency

Before we move on to safe withdrawal methods, let’s discuss why large withdrawals are particularly vulnerable to security threats:

  • Network Congestion: With multiple transactions taking place simultaneously, network congestion can occur, leading to slower processing times and higher transaction fees.
  • Hacking and Phishing Scams: Online exchanges and wallets can be vulnerable to hacking and phishing attacks that can compromise your cryptocurrency and confidential information.
  • Exchange Downtime: If the exchange where you store your cryptocurrency is experiencing downtime or technical difficulties, you may not be able to access your assets for an extended period of time.

Secure Withdrawal Methods

To ensure the safe and secure withdrawal of large amounts of cryptocurrency, follow these steps:

  • Choose a reputable online exchange: Choose an exchange that is well-known, has a good reputation for security, and offers solid customer service.
  • Use a secure wallet: Use a digital wallet that offers advanced security features such as two-factor authentication (2FA), encryption, and cold storage.
  • Verify your identity: Make sure you can verify your identity with a government-issued ID and proof of address.

Top 5 Secure Withdrawal Methods

Here are five secure withdrawal methods worth considering:

  • Binance: Binance is one of the most reputable and easy-to-use exchanges, with a large selection of cryptocurrencies and a strong security record.
  • Coinbase

    : Coinbase is a well-established exchange that offers a simple and secure withdrawal process, with no fees for large withdrawals.

  • Bitstamp: Bitstamp is a reputable online exchange that offers fast and secure cryptocurrency withdrawals, with no transaction fees.
  • Ledger: Ledger is a well-known hardware wallet provider that offers advanced security features, such as cold storage and encryption.

Additional Tips for Safe Withdrawals

In addition to using a trusted exchange and secure wallet, here are some additional tips for safe withdrawals:

  • Monitor your account activity: Monitor your account activity regularly to detect any suspicious transactions.
  • Use a secure connection: Make sure you use a secure connection (HTTPS) when accessing your online exchange or wallet.
  • Keep your software up to date: Keep your operating system, browser, and cryptocurrency software up to date to ensure you have the latest security patches.
  • Avoid phishing scams: Watch out for phishing scams that target users to withdraw large amounts of cryptocurrency.

Can you recover your bitcoins that were lost years ago?

As a bitcoin owner, you’re not the only one wondering if your digital assets are gone. With the rise of cryptocurrency trading and exchanges, it’s become easier and easier to lose track of your coins. In this article, we’ll explore what’s involved in recovering lost bitcoins and provide you with guidelines on how to do it.

Problem: Losing Your Bitcoin Wallet

When you purchased bitcoin, you created a digital wallet using Bitcoin-Qt 7, which is an open-source, lightweight client that allows for seamless communication with the bitcoin network. Unfortunately, wallets can be vulnerable to security breaches or data loss for a number of reasons, including:

  • Hard drive or storage device failure: If your computer’s hard drive or storage device fails, your wallet may become inaccessible.
  • Data corruption or deletion: Accidentally deleting a file or data corruption can cause problems with your wallet, and consequently your coins.
  • Closing a Brokerage or Exchange Account: When you open a bitcoin trading or exchange account, you will likely receive an email notification with instructions for transferring funds. If the platform closes your account or changes its policies, your bitcoins may become inaccessible.

Solution: Recovering Lost Bitcoins

To recover lost bitcoins, follow these steps:

1. Check your email and transaction logs

  • Review all emails you received regarding your bitcoin transaction, including invoices and confirmations.
  • Check for potential spam or phishing emails that may contain instructions or links.

2. Update your wallet software

  • Make sure your Bitcoin-Qt 7 is up to date by visiting the official website (bitcoin.org) and downloading the latest version.
  • Also, review any updates you may have installed since purchasing your wallet.

3. Contact exchanges or brokers (if necessary)

  • If you received an email or notification from a bitcoin exchange or broker, contact their customer support.
  • They can help you recover your account and confirm that your bitcoins are still available.

4. Recreate your wallet

  • If the steps above don’t work, it may be time to recreate your wallet using Bitcoin-Qt 7 or another compatible client.
  • Be sure to follow best practices for creating a new wallet, such as using strong passwords and enabling two-factor authentication.

5. Consider using a backup

  • Back up your wallet data before making any changes.
  • Store this data securely in a separate location, such as an external hard drive or encrypted cloud storage service.

Bottom Line

Losing bitcoins can be frustrating, but it’s not impossible to get them back. By following the steps above and taking proactive measures to protect yourself from data loss, you can increase your chances of regaining access to your bitcoins. Keep in mind that every situation is unique, so don’t hesitate to seek professional help if necessary.

Additional tips:

  • Regularly back up your wallet data using a secure method.
  • Use strong passwords and enable two-factor authentication whenever possible.
  • Keep your operating system and software up to date with the latest security patches.
  • Consider using a reputable bitcoin broker or exchange that offers strong customer support.
