Integrating a TradingView chart into a Python GUI
Integrating a TradingView chart into a Python GUI application requires embedding the TradingView widget within a GUI framework like Tkinter, PyQt, or Kivy. Since TradingView provides embeddable charts through HTML and JavaScript, you can use a web view in the GUI to load the TradingView widget.
Here’s how to do it using Tkinter and PyQt:
Option 1: Using Tkinter
Prerequisites
- Install the
package to enable embedding HTML in Tkinter:tkhtmlview
pip install tkhtmlview
Steps
-
Generate the TradingView widget HTML code from their website:
- Go to TradingView Widget.
- Customize the chart (symbol, style, interval, etc.) and copy the generated iframe code.
-
Embed it in the Tkinter GUI:
Example Code
import tkinter as tk
from tkhtmlview import HTMLLabel
# Create a basic TradingView widget HTML
tradingview_widget = """
"""
# Create a Tkinter window
root = tk.Tk()
root.title("TradingView Chart")
root.geometry("850x650")
# Embed the TradingView widget in the Tkinter GUI
html_label = HTMLLabel(root, html=tradingview_widget)
html_label.pack(fill="both", expand=True)
root.mainloop()
This will display the TradingView chart in a Tkinter window.
Option 2: Using PyQt
Prerequisites
- Install PyQt5:
pip install PyQt5 PyQtWebEngine
Steps
- Use the
fromQWebEngineView
to render the TradingView widget.PyQtWebEngine
Example Code
from PyQt5.QtWidgets import QApplication, QMainWindow, QVBoxLayout, QWidget
from PyQt5.QtWebEngineWidgets import QWebEngineView
class TradingViewApp(QMainWindow):
def __init__(self):
super().__init__()
self.setWindowTitle("TradingView Chart")
self.setGeometry(100, 100, 900, 700)
# Create a widget to hold the layout
widget = QWidget()
layout = QVBoxLayout()
# Create a web engine view for TradingView widget
web_view = QWebEngineView()
# Set the TradingView widget URL
tradingview_url = (
"https://s.tradingview.com/widgetembed/?frameElementId=tradingview_12345&symbol=MSFT"
"&interval=D&symboledit=1&saveimage=1&toolbarbg=f1f3f6&studies=[]&theme=light&style=1"
"&timezone=Etc%2FUTC&withdateranges=1&hideideas=1&locale=en"
)
web_view.setUrl(tradingview_url)
# Add the web view to the layout
layout.addWidget(web_view)
widget.setLayout(layout)
# Set the widget as the central widget
self.setCentralWidget(widget)
# Run the application
if __name__ == "__main__":
app = QApplication([])
window = TradingViewApp()
window.show()
app.exec_()

Notes
-
Dynamic Symbol Changes:
- To allow symbol changes (e.g., user selects a different stock), modify the iframe URL dynamically in your code.
-
Responsive Design:
- Ensure the iframe width and height fit well within your GUI window.
-
Local HTML Files:
- You can save the TradingView widget code as an HTML file and load it into the web view.
