Automated Trading Development in Python, PyQt QCheckBox

The demand for automated trading systems that can automatically execute asset trading is increasing day by day in the modern financial market. This article will cover the basics of developing an automated trading system using Python, as well as ways to improve the user interface using PyQt’s QCheckBox. Through this, users will understand the basic structure of an automated trading system and be able to develop a simple application they can use directly.

1. What is an Automated Trading System?

An automated trading system refers to a program that executes trades based on pre-set rules. Generally, this system analyzes past data to identify trading signals and proceeds with trades automatically without user intervention. Such systems can quickly respond to market fluctuations and have significant advantages in eliminating human emotional factors.

1.1 Components of an Automated Trading System

An automated trading system consists of the following components:

  • Data Collection: Collects price data in real-time.
  • Strategy Development: Establishes trading strategies and codes them.
  • Signal Generation: Generates trading signals (buy, sell, etc.).
  • Order Execution: Executes trading orders based on signals.
  • Performance Evaluation: Analyzes trading performance and adjusts strategies.

2. What is PyQt?

PyQt is a Qt library for Python that facilitates the easy development of GUI applications. PyQt provides various widgets to create applications that users can interact with visually. QCheckBox provides a checkbox that users can select and is useful for enabling simple settings or options.

3. Example of Using PyQt QCheckBox

In this section, we will implement a settings screen for an automated trading system using PyQt’s QCheckBox. Users can select specific trading strategies or enable or disable additional options.

3.1 Basic Structure of a PyQt Application

When developing an application with PyQt, the structure generally involves creating a QApplication object, setting up the main window, and then running the event loop. Below is an example of a simple PyQt application structure:


from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QCheckBox, QPushButton

class MyApp(QWidget):
    def __init__(self):
        super().__init__()

        self.initUI()

    def initUI(self):
        layout = QVBoxLayout()

        # Add checkboxes
        self.checkBox1 = QCheckBox("Select Strategy A", self)
        self.checkBox2 = QCheckBox("Select Strategy B", self)

        layout.addWidget(self.checkBox1)
        layout.addWidget(self.checkBox2)

        # Add confirmation button
        self.btn = QPushButton("Confirm", self)
        self.btn.clicked.connect(self.onClick)

        layout.addWidget(self.btn)

        self.setLayout(layout)
        self.setWindowTitle("Automated Trading System Settings")
        self.show()

    def onClick(self):
        if self.checkBox1.isChecked():
            print("Strategy A has been selected.")
        if self.checkBox2.isChecked():
            print("Strategy B has been selected.")

if __name__ == '__main__':
    import sys
    app = QApplication(sys.argv)
    ex = MyApp()
    sys.exit(app.exec_())
    

3.2 Running the Application

If you save the above code as a Python file and run it, a basic PyQt application with two checkboxes and a confirmation button will be created. When users select the checkboxes and press the confirm button, messages indicating the selected strategies will be printed.

3.3 Receiving Settings with QCheckBox

When developing an automated trading system, it is important to allow users to easily set their preferred strategies or trading conditions. By utilizing QCheckBox, users can simply select their desired conditions. For example, checkboxes can be added to select technical indicators such as MACD and RSI, allowing users to modify how the system operates according to their desired strategies.


class MyApp(QWidget):
    def __init__(self):
        super().__init__()

        self.initUI()

    def initUI(self):
        layout = QVBoxLayout()

        # Add checkboxes
        self.macdCheckBox = QCheckBox("Use MACD", self)
        self.rsiCheckBox = QCheckBox("Use RSI", self)

        layout.addWidget(self.macdCheckBox)
        layout.addWidget(self.rsiCheckBox)

        # Add start button
        self.startBtn = QPushButton("Start Automated Trading", self)
        self.startBtn.clicked.connect(self.startTrading)

        layout.addWidget(self.startBtn)

        self.setLayout(layout)
        self.setWindowTitle("Automated Trading System Settings")
        self.show()

    def startTrading(self):
        print("Starting automated trading.")
        if self.macdCheckBox.isChecked():
            print("MACD strategy has been activated.")
        if self.rsiCheckBox.isChecked():
            print("RSI strategy has been activated.")
        
        # Call additional automated trading logic
        self.runAutomatedTrading()

    def runAutomatedTrading(self):
        # Implement actual automated trading logic
        pass
    

3.4 Saving User Settings

To continuously utilize the user-defined settings within the program, it is possible to save them to external storage via the network or a local file. For instance, saving in a format such as a JSON file allows loading previous settings when the program is run again.


import json

class MyApp(QWidget):
    def __init__(self):
        super().__init__()
        self.loadSettings()  # Load settings at startup
        self.initUI()

    def initUI(self):
        layout = QVBoxLayout()
        self.macdCheckBox = QCheckBox("Use MACD", self)
        self.rsiCheckBox = QCheckBox("Use RSI", self)

        self.macdCheckBox.setChecked(self.settings.get("macd", False))
        self.rsiCheckBox.setChecked(self.settings.get("rsi", False))

        layout.addWidget(self.macdCheckBox)
        layout.addWidget(self.rsiCheckBox)

        self.startBtn = QPushButton("Start Automated Trading", self)
        self.startBtn.clicked.connect(self.startTrading)
        layout.addWidget(self.startBtn)

        self.setLayout(layout)
        self.setWindowTitle("Automated Trading System Settings")
        self.show()

    def loadSettings(self):
        try:
            with open('settings.json', 'r') as f:
                self.settings = json.load(f)
        except FileNotFoundError:
            self.settings = {}

    def startTrading(self):
        print("Starting automated trading.")
        if self.macdCheckBox.isChecked():
            print("MACD strategy has been activated.")
        if self.rsiCheckBox.isChecked():
            print("RSI strategy has been activated.")
        
        self.settings["macd"] = self.macdCheckBox.isChecked()
        self.settings["rsi"] = self.rsiCheckBox.isChecked()
        
        with open('settings.json', 'w') as f:
            json.dump(self.settings, f)  # Save settings

        self.runAutomatedTrading()

    def runAutomatedTrading(self):
        # Implement actual automated trading logic
        pass
