Ethereum: Binance: Partial Ledger Depth Streams
Partial Ledger Depth Streams 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 ledger depth.
What is partial ledger depth?
Partial ledger depth refers to the ability of a market maker or liquidity provider to provide information about the current state of the order book for a specific asset at any given point in time. This information can be used by users who want to execute trades with greater precision and accuracy.
Binance Partial Ledger Depth Streams
Binance offers partial ledger depth streams 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 it in your Binance account)
- The
stream.partialBookDepthendpoint
Here is some sample code for JavaScript and using 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 to get partial book depth data
socket.send(JSON.stringify({
'method': 'GET',
'path': '/spot/partialbookdepth?symbol=ETH&limit=100'
}));
// Set up 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 API request 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 from 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_KEYandYOUR_API_SECRETwith your actual Binance API keys.
- Partial book depth streams may have usage restrictions and requirements to create an account or purchase a plan on Binance.
- Be aware of the risks of using the WebSocket API, including potential security holes.
