Welcome to the final lesson in our Free Ai course on AI-Agentic Design Patterns with AutoGen!
The last article focused on building an interactive Chess Game with AutoGen. In this lesson, we will explore how to use a group of collaborative agents to plan and generate a stock report.
We will build a group chat with multiple agents, each with specific roles, to complete the task of writing a blog post about Nvidia’s stock performance over the past month. Let’s dive in!

Environment Setup for Agent
First, set up the environment and define the agents’ roles.
Importing the Necessary Libraries and Configurations
We must import the necessary configurations and libraries, including OpenAI’s API key and LLM configuration.
from autogen.utils import get_openai_api_key
from autogen.configs import LLMConfig
from autogen.agents import ConversableAgent
from autogen.coding import LocalCommandLineCodeExecutor
# Importing the OpenAI API key
api_key = get_openai_api_key()
# Defining LLM Configuration
llm_config = LLMConfig(
model_name='gpt-4-turbo',
api_key=api_key,
temperature=0.7,
max_tokens=150
)Making a Blog post using Agent
The task is to write a blog post about Nvidia’s stock price performance over the past month. Today’s date is August 15, 2024.
task = "Write a blogpost about the stock price performance of Nvidia in the past month. Today's date is 2024-04-23."Building a Group Chat
We’ll set up a group chat with the following agents:
- User_proxy (Admin): Allows the user to comment on the report and ask the writer to refine it.
- Planner: Determines relevant information needed to complete the task.
- Engineer: Writes code using the defined plan by the planner.
- Executor: Executes the code written by the engineer.
- Writer: Writes the report.
import autogen
user_proxy = autogen.ConversableAgent(
name="Admin",
system_message="Give the task, and send instructions to writer to refine the blog post.",
code_execution_config=False,
llm_config=llm_config,
human_input_mode="ALWAYS",
)
planner = autogen.ConversableAgent(
name="Planner",
system_message="Given a task, please determine what information is needed to complete the task. "
"Please note that the information will all be retrieved using Python code. "
"After each step is done by others, check the progress and instruct the remaining steps. "
"If a step fails, try to work around.",
description="Planner. Given a task, determine what information is needed to complete the task. "
"After each step is done by others, check the progress and instruct the remaining steps.",
llm_config=llm_config,
)
engineer = autogen.AssistantAgent(
name="Engineer",
llm_config=llm_config,
description="An engineer that writes code based on the plan provided by the planner.",
)
executor = autogen.ConversableAgent(
name="Executor",
system_message="Execute the code written by the engineer and report the result.",
human_input_mode="NEVER",
code_execution_config={
"last_n_messages": 3,
"work_dir": "coding",
"use_docker": False,
},
)
writer = autogen.ConversableAgent(
name="Writer",
llm_config=llm_config,
system_message="Writer. Please write blogs in markdown format (with relevant titles) "
"and put the content in pseudo ```md``` code block. "
"You take feedback from the admin and refine your blog.",
description="Writer. Write blogs based on the code execution results and take feedback from the admin to refine the blog.",
)Defining the Group Chat
We’ll define the group chat with the agents and specify the allowed transitions between them.
groupchat = autogen.GroupChat(
agents=[user_proxy, engineer, writer, executor, planner],
messages=[],
max_round=10,
allowed_or_disallowed_speaker_transitions={
user_proxy: [engineer, writer, executor, planner],
engineer: [user_proxy, executor],
writer: [user_proxy, planner],
executor: [user_proxy, engineer, planner],
planner: [user_proxy, engineer, writer],
},
speaker_transitions_type="allowed",
)
manager = autogen.GroupChatManager(
groupchat=groupchat, llm_config=llm_config
)Starting the Group Chat
We’ll initiate the group chat with the task.
groupchat_result = user_proxy.initiate_chat(
manager,
message=task,
)Conversation Workflow
Admin
Admin (to chat_manager):
Write a blogpost about the stock price performance of Nvidia in the past month. Today's date is 2024-04-23.Planner
Python Planner (to chat_manager):
To write a blog post about the stock price performance of Nvidia for the past month, you'll need to gather, analyze, and describe several pieces of information related to Nvidia's stock. Here are the key steps and the required data to complete each step:
### Step 1: Gathering the Stock Data for Nvidia
- **Date Range**: From March 23, 2024, to April 23, 2024.
- **Data Points Needed**:
- Daily opening prices
- Daily closing prices
- Daily highs and lows
- Daily trading volume
### Step 2: Analyze the Stock Data
- **Analysis Types**:
- Calculate percentage changes between opening and closing prices daily.
- Determine the overall increase or decrease in stock price over the month.
- Identify the days with the highest and lowest trading volumes.
- Note any unusual peaks or troughs in the stock price and correlate them with specific events if possible (product launches, earnings reports, etc.).
### Libraries and Tools You Can Use in Python:
- **pandas**: For data manipulation and analysis.
- **matplotlib** or **seaborn**: For creating visualizations of the stock data.
- **yfinance** or **Alpha Vantage API**: To retrieve historical stock data.
### Step 3: Write the Blog Post
- **Content Layout**:
- Introduction: Provide an overview of Nvidia and the purpose of the analysis.
- Main Analysis: Describe the stock performance with the visual aids and data points mentioned above.
- Conclusion: Summarize the analysis and potentially give an outlook based on the observed trends.
### Additional Considerations:
Ensure that any data used for financial analysis is up-to-date and sourced responsibly.
### Next Steps:
- I'll guide you through coding to fetch the stock data for Nvidia from March 23, 2024, to April 23, 2024, using the `yfinance` library in Python. Let me know when you're ready to proceed or if you need help setting up your Python environment!

Engineer (to chat_manager):
Before we fetch the stock data for Nvidia, please make sure you have the following requirements set up in your Python environment:
1. Python is installed on your system.
2. You have installed the `pandas` and `yfinance` packages. If not, you can install them using pip:
```sh
pip install pandas yfinance
Let me know when you have confirmed the setup, and then I will provide you with the Python script to fetch the historical stock data for Nvidia.

Executor (to chat_manager):
exitcode: 127 (execution failed)
Code output:

Admin (to chat_manager):
It looks like there might be a problem with your Python installation, or pip might not be properly set up in your system's path. Let's resolve this issue step-by-step:
### Option 1: Check if Python and pip are properly installed
1. **Verify Python Installation:**
Open your command line interface (CLI) and type:
```bash
python --version
or
bash
python3 --version
This command should return the version of Python installed. If it doesn't, Python may not be installed correctly.
Find pip: If Python is installed, check for pip by typing:
bash
pip --version
or
bash
pip3 --version
This will tell you if pip is installed and its path.

#### Engineer
```python
Engineer (to chat_manager):
Since Python is installed but pip is not recognized, this suggests an issue with your path settings for pip. You can manually add pip to your system's path, or you might need to use a different command to install packages. Often, on some systems, you have to use `pip3` instead of `pip`. Let's try using `pip3` to install the required packages.
Please try running the following command:
```sh
pip3 install pandas yfinance

Engineer (to chat_manager):
Great! Now that the required packages are installed, let's proceed with fetching the stock data for Nvidia from March 23, 2024, to April 23, 2024, using the `yfinance` library.
Here's the Python script to fetch and process the data:
```python
import yfinance as yf
import pandas as pd
# Define the date range
start_date = "2024-03-23"
end_date = "2024-04-23"
# Fetch the stock data for Nvidia
data = yf.download("NVDA", start=start_date, end=end_date)
# Process the data
data['Date'] = data.index
data['Percentage Change'] = (data['Close'] - data['Open']) / data['Open'] * 100
# Calculate the overall increase or decrease
overall_change = (data['Close'][-1] - data['Close'][0]) / data['Close'][0] * 100
# Identify the days with the highest and lowest trading volumes
highest_volume_day = data.loc[data['Volume'].idxmax()]
lowest_volume_day = data.loc[data['Volume'].idxmin()]
Please execute this script and provide the results.

#### Executor
