Introduction

TradingView is one of the most popular platforms for traders and investors worldwide. With its intuitive interface and powerful charting tools, TradingView provides a perfect environment for traders to analyze market trends and make informed decisions. One of the most powerful features of TradingView is its Websocket API, which allows developers to access real-time market data and execute trades programmatically. In this guide, we will explore how to use TradingView Websocket with Python, one of the most popular programming languages for data analysis and trading automation.

What is TradingView Websocket?

TradingView Websocket is a real-time streaming API that allows developers to receive real-time data from the TradingView platform. This data includes market prices, indicators, and other trading data that can be used to analyze market trends and execute trades programmatically. TradingView Websocket is an essential tool for traders who want to automate their trading strategies and make informed decisions based on real-time market data.

Why use Python for TradingView Websocket?

Python is one of the most popular programming languages for data analysis and trading automation. It has a rich set of libraries and tools that make it easy to work with data and automate trading strategies. Python also has a large community of developers who contribute to open-source libraries and provide support for beginners. Using Python for TradingView Websocket is an excellent choice for traders who want to automate their trading strategies and leverage the power of data analysis.

Getting Started with TradingView Websocket and Python

Before we start using TradingView Websocket with Python, we need to set up our development environment. Here are the steps:

Install Python on your machine. You can download Python from the official website (https://www.python.org/downloads/).
Install the websocket library for Python. You can use the pip package manager to install the websocket library by typing the following command in your terminal:

pip install websocket-client

3. Create a TradingView account (if you don’t have one already) and generate an API key. You can do this by following the instructions on the TradingView website.

Connecting to TradingView Websocket

Now that we have set up our development environment and generated an API key, we can start connecting to TradingView Websocket. Here are the steps:

Import the websocket library in your Python code:

import websocket

Create a websocket connection to the TradingView server:

ws = websocket.WebSocketApp(“wss://data.tradingview.com/socket.io/websocket?v=1.2″, on_message=on_message, on_error=on_error, on_close=on_close)

The “wss://data.tradingview.com/socket.io/websocket?v=1.2” is the URL of the TradingView server. We also specify three callback functions: on_message, on_error, and on_close. These functions will be called when we receive a message, encounter an error, or close the connection.

Define the callback functions:

def on_message(ws, message):
print(message)

def on_error(ws, error):
print(error)

def on_close(ws):
print(“### closed ###”)

def on_open(ws):
print(“### connected ###”)

The on_message function will be called when we receive a message from the TradingView server. We can use this function to process the real-time data and execute trades programmatically. The on_error function will be called when we encounter an error. The on_close function will be called when we close the connection. The on_open function will be called when we open the connection.

Open the websocket connection:

ws.on_open = on_open
ws.run_forever()

The ws.on_open function will be called when we open the connection. The ws.run_forever function will keep the connection open and listen for incoming messages.

Receiving Real-time Data from TradingView Websocket

Now that we have connected to TradingView Websocket, we can start receiving real-time data. Here are some of the most commonly used data streams:

Price Data

We can receive real-time price data for various financial instruments using the “quote” data stream. Here is an example:

ws.send(‘{“_time”:0,”symbol”:”AAPL”,”ticks”:”price”}’)

This will send a request to the TradingView server to receive real-time price data for AAPL (Apple Inc.). The “ticks”:”price” parameter tells the server to send only price data (not volume or other indicators).

Indicator Data

We can receive real-time indicator data using the “indicator” data stream. Here is an example:

ws.send(‘{“_time”:0,”symbol”:”AAPL”,”ticks”:”MACD”}’)

This will send a request to the TradingView server to receive real-time MACD (Moving Average Convergence Divergence) indicator data for AAPL.

Order Book Data

We can receive real-time order book data using the “orderbook” data stream. Here is an example:

ws.send(‘{“_time”:0,”symbol”:”AAPL”,”ticks”:”orderbook”}’)

This will send a request to the TradingView server to receive real-time order book data for AAPL.

Executing Trades Programmatically

Now that we can receive real-time data from TradingView Websocket, we can start executing trades programmatically. Here is an example:

def on_message(ws, message):
data = json.loads(message)
if “trade” in data:
trade = data[“trade”]price = trade[“price”]symbol = trade[“symbol”]volume = 1
type = “market”
side = “buy”
order = {“symbol”:symbol,”volume”:volume,”type”:type,”side”:side}
api.submit_order(order)

This code will execute a market order for 1 share of the instrument that generated the trade signal. We use the TradingView API to submit the order programmatically.

Conclusion

TradingView Websocket is a powerful tool for traders who want to automate their trading strategies and make informed decisions based on real-time market data. By using Python, we can easily connect to TradingView Websocket and receive real-time data. We can also execute trades programmatically using the TradingView API. By mastering TradingView Websocket with Python, we can take our trading to the next level.
