Introduction

Automated trading systems, enhanced by AI agents, learn from historical data, predict market trends, and execute trades autonomously. This guide demonstrates building such a system using advanced technologies and cloud services, notably the .NET C# Semantic Kernel for seamless AI model integration.

Prerequisites

• Azure Subscription: Access to Microsoft Azure services.
• Development Tools: Visual Studio 2022 or Visual Studio Code with .NET Core SDK, Python 3.8 with relevant libraries.
• Azure CLI: For command-line Azure resource management.
• Docker: Installed locally.
• Azure Kubernetes Service (AKS): Basic familiarity.
• .NET C# Semantic Kernel: Installed and configured.

Architectural Overview

The system comprises:

• AI Model: Developed in Python using Azure Machine Learning.
• .NET C# Semantic Kernel: Integrates AI capabilities into the .NET Core application.
• ASP.NET Core Web API: Backend for AI agent interaction and trade execution.
• Azure Cosmos DB: Stores trading data and model predictions.
• Azure Key Vault: Securely stores sensitive information (API keys, connection strings).
• Azure Functions: Handles event-driven processes like real-time data ingestion.
• Azure Kubernetes Service (AKS): Hosts the containerized application for scalability and high availability.
• Azure AI Services: Provides supplementary AI capabilities (optional).

Development Environment Setup

Install the .NET Core SDK, Visual Studio (or VS Code), the .NET C# Semantic Kernel, Python 3.8 , necessary Python libraries (pandas, numpy, scikit-learn, joblib, azureml-sdk), the Azure CLI, and Docker Desktop.

AI Model Development (Python & Azure ML)

1. Define Trading Strategy: Determine the AI model's objective (e.g., stock price prediction, market trend classification).
2. Set Up Azure ML Workspace: Create a resource group and an Azure Machine Learning workspace using the Azure CLI.
3. Develop the AI Model: Create a Python script (e.g., train_model.py) to train the model using relevant libraries.
4. Register the Model in Azure ML: Register the trained model within your Azure ML workspace.

Integrating .NET C# Semantic Kernel for AI Agents

1. Install NuGet Package: Add the Microsoft.SemanticKernel NuGet package to your .NET project.
2. Integrate AI Model: Create a class (e.g., TradingAgentKernel) to define the AI agent's functions, using the Semantic Kernel to call the AI model via a REST API or other suitable method.
3. Azure OpenAI Service (Optional): Integrate LLMs like GPT-3 using the Semantic Kernel's Azure OpenAI backend configuration.

Building the .NET Core Web API

1. Initialize Project: Create a new ASP.NET Core Web API project.
2. Install NuGet Packages: Install necessary packages for Cosmos DB, Azure Key Vault, and Semantic Kernel.
3. Set Up Project Structure: Organize the project into Controllers, Services, and Models.
4. Configure App Settings: Create appsettings.json with placeholders for Azure Key Vault and Cosmos DB configurations.

Integrating the AI Model into the .NET Core Application

1. Use Semantic Kernel: Integrate the TradingAgentKernel class into your API controllers.
2. Implement Controller: Create API controllers to handle trade execution requests, using the Semantic Kernel to obtain predictions from the AI model.

Azure Cosmos DB Data Storage

Use the Cosmos DB .NET SDK to interact with the database, storing trading data and model predictions.

Azure Key Vault for Secure Secrets Management

1. Create Azure Key Vault: Create a Key Vault instance using the Azure CLI.
2. Store Secrets: Store sensitive information (connection strings, API keys) in the Key Vault.
3. Configure Application: Configure your application to retrieve secrets from the Key Vault using the appropriate .NET libraries.

Event-Driven Processing with Azure Functions

1. Create Azure Function Project: Create a new Azure Function project using the Azure Functions Core Tools.
2. Implement Function: Create a function (e.g., MarketDataIngestion) to handle real-time data ingestion and trigger trading actions based on events.
3. Deploy Function: Deploy the function to Azure.
4. Integrate with Main Application: Use Azure Event Grid or Service Bus for communication between the function and the main application.

Docker Containerization

Create a Dockerfile to containerize your application.

Deployment to Azure Kubernetes Service (AKS)

Deploy your containerized application to an AKS cluster.

Monitoring and Logging

Enable Azure Monitor for Containers and use Application Insights for application-level monitoring and logging.
