Ethereum: Binance: Partial Depth of Book Feeds

Partial Depth of Book Feeds is an advanced feature offered by Binance, a leading cryptocurrency exchange. This feature allows users to connect their Ethereum accounts to the Binance API and access real-time market data, including partial depth of book.

What is partial depth of book?

Partial depth of book refers to the ability of a market maker or liquidity provider to provide information about the current state of the order book for a given asset at a given time. This information can be used by users who want to execute trades with greater precision and accuracy.

Binance’s Partial Depth of Book Feeds

Binance offers partial depth of book feeds for Ethereum, allowing users to access this data via the Binance API. To use partial book depth streams, you will need:

• A valid Ethereum account on Binance

• A Binance API key (create one in your Binance account)

• The stream.partialBookDepth endpoint

Here is a sample code for using JavaScript and WebSocket:

const APIKEY = 'YOUR_API_KEY';
const APISECRET = 'YOUR_API_SECRET';
const socket = new WebSocket('wss://stream.binance.com/spot/api/v4/stream/partialbookdepth');
socket.onmessage = (event) => {
const partialBookDepthData = JSON.parse(event.data);
console.log(partialBookDepthData);
};
socket.onopen = () => {
// Send a request to the API for partial book depth data
socket.send(JSON.stringify({
"method": "GET",
"path": "/spot/partialbookdepth?symbol=ETH&limit=100"
}));
// Configure event listeners for incoming messages
socket.onmessage = (event) => {
const partialBookDepthData = JSON.parse(event.data);
console.log(partialBookDepthData);
};
};

const APIKEY = 'YOUR_API_KEY';
const APISECRET = 'YOUR_API_SECRET';
$socket = new WebSocket('wss://stream.binance.com/spot/api/v4/stream/partialbookdepth');
$socket->onmessage = function(event) {
$partialBookDepthData = JSON_decode($event->data, true);
echo "Partial Book Depth Data: " . json_encode($partialBookDepthData) . "\n";
};
$socket->onopen = function() {
// Send a request to the API for partial book depth data
$socket->send(JSON.stringify({
"method": "GET",
"path": "/spot/partialbookdepth?symbol=ETH&limit=100"
}));
// Configure event listeners for incoming messages
$socket->onmessage = function(event) {
$partialBookDepthData = JSON_decode($event->data, true);
echo "Partial Book Depth Data: " . json_encode($partialBookDepthData) . "\n";
};
};

Using the WebSocket API

To use partial book depth streams with JavaScript, you need to create a WebSocket connection to wss://stream.binance.com/spot/api/v4/stream/partialbookdepth. You can then send requests to this endpoint and listen for incoming messages.

For PHP, you can use the WebSocket library to connect to the Binance API and access partial book depth data.

Important Notes

• Make sure to replace YOUR_API_KEY and YOUR_API_SECRET with your actual Binance API keys.

• Partial book depth streams may have usage limits and requirements for creating an account or purchasing a plan on Binance.

• Be aware of the risks associated with using WebSocket APIs, including potential security vulnerabilities.
