+This script is a command-line tool designed to generate a trading signal for a stock. You run it from your terminal or command prompt, not from within a Python IDE's run button without configuration.
+This script is generated by Qwen-Max, Gemini Pro 2.5, and Grok4 Fast.
+
+## Step 1: Install Prerequisites
+First, you need to install Python and all the necessary libraries. The most complex one is TA-Lib, which requires a separate installation before the Python wrapper.
+
+Install the TA-Lib C Library: This is the underlying engine for the talib Python package.
+
+Windows: Download the appropriate .whl file from Unofficial Windows Binaries for Python Extension Packages and install it using pip.
+
+macOS: Use Homebrew: brew install ta-lib
+
+Linux (Ubuntu/Debian): sudo apt-get install libta-lib-dev
+
+Install Python Libraries: Once the C library is installed, you can install the required Python packages using pip.
+
+Bash
+
+pip install yfinance pandas numpy xgboost scikit-learn TA-Lib requests
+## Step 2: Save the Script
+Save the code you provided into a file. Let's name it signal_generator.py. Make sure you save it in a directory you can easily access from your terminal.
+
+## Step 3: Run from the Command Line
+Open your terminal (on macOS/Linux) or Command Prompt/PowerShell (on Windows) and navigate to the directory where you saved the file.
+
+The basic command structure is:
+python signal_generator.py [TICKERS] [OPTIONS]
+
+Arguments Explained:
+tickers (Required): The list of stock ticker symbols you want to analyze, separated by spaces. The first ticker is the default target unless specified otherwise.
+
+--target (Optional): Specifies which ticker from the list to generate the signal for.
+
+--period (Optional): The amount of historical data to download. The default is 2y (2 years). Other valid options include 1y, 6mo, 3mo, 1d, etc.
+
+## Examples
+Here are a few examples of how to run the script:
+
+Example 1: Basic Signal for a Single Stock
+This will generate a signal for Apple (AAPL), using the default 2-year period.
+
+Bash
+
+python signal_generator.py AAPL
+Example 2: Signal for a Target Stock with Market Context
+This command downloads data for SPY, QQQ, and NVDA but specifically generates the trading signal for NVDA.
+
+Bash
+
+python signal_generator.py SPY QQQ NVDA --target=NVDA
+Example 3: Including Market Indexes
+This command generates a signal for the QQQ ETF and includes the VIX (volatility), TNX (10-year treasury yield), and DXY (dollar index) for a richer market context.
+
+Bash
+
+python signal_generator.py QQQ VIX TNX DXY
+Example 4: Using a Shorter Historical Period
+This generates a signal for Microsoft (MSFT) using only the last 6 months of data.
+
+Bash
+
+python signal_generator.py MSFT 
+After running any of these commands, the script will print the final signal directly to your terminal.
