I can help you write an article on Ethereum: Node.js Talib Calculation of Simple Moving Average differs from Binance and TradingView. However, please note that I’ll provide a general outline and some sample code, but you should adjust it according to your specific requirements.

Ethereum: Node.js Talib Calculation of Simple Moving Average

The Simple Moving Average (SMA) is a popular technical indicator used in various forms of trading and analysis. In this article, we will explore the differences between calculating SMA using talib for Ethereum nodes and traditional Binance and TradingView platforms.

Introduction to Talib Module

We start by installing the talib module, which provides functions for calculating various statistical indicators, including SMAs.

const Talib = require('talib');

Calculating SMA with Node.js

Now, let’s create a WebSocket connection to the Binance market and use talib to calculate the SMA for the BTC/USDT pair.

First, you need to install the required dependencies:

npm install talib

Next, we’ll create a socket to connect to the Binance market.

const WebSocketBinance_BTCUSDT = new WebSocket('wss://binance.com/bapi/v3/marketDataStream?symbol=BTCUSDT&options=1&type=stream');


// Function to process market data

function processData(data) {

  const chartData = Talib.getChart('4H', '1000');

  // ...

}


// Subscribe to the Binance stream

WebSocketBinance_BTCUSDT.on('open', () => {

  WebSocketBinance_BTCUSDT.on('message', (data) => {

    processData(data);

  });

});


// Start the socket

WebSocketBinance_BTCUSDT.connect();

Calculating SMA with Traditional Platforms

For comparison, let’s use traditional platforms like Binance and TradingView to calculate the same SMA.

First, install talib on these platforms:

npm install talib

Next, create a WebSocket connection to the platform.

const Talib = require('talib');


// Function to process market data

function processData(data) {

  const chartData = Talib.getChart('4H', '1000');

  // ...

}


// Subscribe to the platform stream

const socket = new WebSocket({

  host: 'api.binance.com',

  port: 443,

  protocol: 'https',

});


// Send a request to the platform for market data

socket.onmessage = (event) => {

  const data = JSON.parse(event.data);

  processData(data);

};

Conclusion

In this article, we explored the differences between calculating SMA using talib on Ethereum nodes and traditional platforms like Binance and TradingView. While both methods can produce accurate results, they have distinct characteristics.

Ethereum nodes, such as those provided by Node.js talib, offer a more direct connection to the underlying blockchain data stream, making it easier to calculate SMAs. On the other hand, traditional platforms provide additional layers of abstraction and may require more setup and configuration.

By understanding these differences, you can choose the best approach for your specific use case and improve your trading decisions with accurate SMA calculations.
