## What is This?

**Investor Paradise** is a multi-agent AI system that analyzes NSE (National Stock Exchange) stock data by combining:

- **Quantitative Analysis**: 25 specialized tools for calculating returns, detecting patterns, analyzing risk metrics, index-based screening, market cap filtering, and sector+cap combinations
- **Qualitative Research**: Dual-source news correlation (in-house PDF database + real-time web search) to explain *why* stocks moved
- **Security**: Built-in prompt injection defense to protect against malicious queries
- **Synthesis**: Professional investment recommendations combining data + news + risk assessment
- **Real-time Streaming**: Progressive response display for faster feedback
- **Performance**: Parquet caching system with automatic GitHub downloads for instant startup

Unlike traditional stock screeners (static filters) or generic chatbots (hallucinated data), this system uses **five specialized agents** working in parallel/sequence to deliver research-grade analysis in seconds:

1. **Entry Router** - Security & intent classification
2. **Market Analyst** - Quantitative analysis with 25 tools
3. **PDF News Scout** - Historical news from local database
4. **Web News Researcher** - Real-time news from web search
5. **CIO Synthesizer** - Investment strategy synthesis

---

## Why Use This?

**Problem**: Existing tools either show raw data without interpretation (screeners) or provide generic insights without real market data (LLMs).

**Solution**: Investor Paradise bridges the gap by:

✅ **Explaining causality**: Connects price movements to news events (✅ Confirmation / ⚠️ Divergence)  
✅ **Multi-step workflows**: Backtest strategy → Rank results → Find news catalysts → Generate recommendations  
✅ **Grounded in reality**: Works with actual NSE historical data (2020-2025, 2000+ symbols)  
✅ **Security-first**: Dedicated agent filters prompt injection attacks  
✅ **Actionable output**: Clear 🟢 Buy / 🟡 Watch / 🔴 Avoid recommendations with reasoning  

**Target Users**: Retail investors, equity researchers, developers building financial AI systems.

## Key Features

### 🎨 Enhanced CLI Experience (Rich Library)

Beautifully formatted terminal output with:

- **Syntax highlighting** for code and data tables
- **Progress spinners** with real-time agent activity tracking
- **Styled panels** for investment reports with color-coded signals (🟢 Buy / 🟡 Watch / 🔴 Avoid)
- **Responsive layouts** that adapt to terminal width
- **Live updates** showing which tools are executing in real-time

### 🔐 Secure API Key Management (Keyring)

Smart multi-tier API key storage with automatic fallback:

- **System keyring integration**: Securely stores API key in OS credential manager (macOS Keychain, Windows Credential Locker, Linux Secret Service)
- **Automatic fallback**: Uses encrypted config file if keyring unavailable
- **Priority hierarchy**: Environment variable > Keyring > Config file > User prompt
- **One-time setup**: Enter API key once, securely saved for future sessions
- **Easy reset**: `--reset-api-key` flag to update stored credentials

```bash
# First run: Prompts for API key and saves to keyring
uv run cli.py
# ⚠️  Google API Key not configured
# Get your free API key from: https://aistudio.google.com/apikey
# Enter your Google API Key: ********
# ✅ API key securely saved to system keyring

# Subsequent runs: Uses stored key automatically
uv run cli.py
# (No prompt - loads from keyring)

# Reset stored key
uv run cli.py --reset-api-key
# ✅ API key removed from keyring
```

### 💾 Intelligent Memory Management (Event Compaction)

- **Automatic context optimization** compresses conversation history to stay within token limits
- **Smart summarization** preserves critical information while reducing context size by 60-80%
- **Long conversations supported** without performance degradation
- **Cost-efficient** by minimizing redundant token usage across multi-turn dialogs

### 💰 Token Tracking & Cost Analysis

Built-in usage monitoring for transparency:

```text
📊 Token Usage by Model:
  • gemini-2.5-flash-lite: 70,179 in + 385 out = 70,564 total ($0.0054)
  • gemini-2.5-flash: 82,176 in + 2,019 out = 84,195 total ($0.0135)
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  Combined: 154,759 tokens ($0.0189)
⏱️  Processing time: 53.26s
💡 Queries this session: 2
```

- **Per-model breakdown**: Cost attribution across the 5-agent pipeline
- **Session totals**: Cumulative usage tracking
- **Real-time updates**: Live cost display after each query

### 🗄️ Session Management (Database-Backed)

Persistent conversation history with SQLite:

- **Multi-session support**: Create unlimited named sessions
- **Session switching**: Jump between conversations with `switch` command
- **History persistence**: Resume analysis from days/weeks ago
- **Auto-cleanup**: Configurable retention (default: 7 days)
- **User isolation**: Each user ID gets separate session namespace

```bash
# CLI session commands
switch  # Browse and switch between past sessions
clear   # Clear current session history
exit    # Save and exit (history preserved)
```

### 💾 Performance Optimizations & Caching

#### Parquet Caching System

- **Faster data loading**: Optimized with Parquet format for 1M+ rows
- **Automatic cache generation**: Downloads from GitHub releases on first run
- **4 cache files**:
  - `combined_data.parquet` (49MB): Stock price data
  - `nse_indices_cache.parquet` (44KB): Index constituents (NIFTY50, NIFTYBANK, etc.)
  - `nse_sector_cache.parquet` (22KB): Sector mappings (2,050+ stocks, 31 sectors)
  - `nse_symbol_company_mapping.parquet` (89KB): Symbol→Company name lookup
- **Cache refresh**: Use `--refresh-cache` flag to download latest data from GitHub
- **Offline-ready**: Cache files work without CSV source data

#### Runtime Optimizations

- **Lazy loading**: Models instantiated only when needed
- **Parallel news agents**: PDF + web search run concurrently
- **Streaming responses**: Progressive output display for better UX (CLI)

```bash
# First run: Downloads cache from GitHub (~50MB total)
uv run cli.py
# ⬇️  Downloading cache files from GitHub releases...
# ✅ All 4 cache files ready

# Refresh cache (optional, downloads latest data)
uv run cli.py --refresh-cache
```

## Running the Agent

### Option 1: Web UI (ADK Web)

**Best for**: Interactive exploration, multi-turn conversations, visual analysis

> **Note for Local Clones**: If you cloned this repo and are running ADK web for the first time, you need to download data files first:

> ```bash
> # One-time setup: Download required data files (~50MB)
> python setup_data.py
> 
> # Then start the web server
> adk web . --log_level INFO
> ```
>
> The CLI automatically handles data downloads, so `setup_data.py` is only needed for ADK web usage.

```bash
# Start the ADK web server
adk web . --log_level INFO

# Output:
# 🚀 Starting ADK web server...
# 📂 Pre-loading NSE data...
# ✅ Data loaded: 1,234,567 rows, 2,345 symbols
# 🌐 Server running at http://localhost:8000
```

Open your browser to `http://localhost:8000` and start chatting with the agent.

**Optional Flags:**

```bash
adk web . --port 8080           # Custom port
adk web . --log_level DEBUG     # Verbose logging
adk web . --host 0.0.0.0        # Allow external access
```

---

### Option 2: Command Line (CLI)

**Best for**: Quick queries, automation, scripting, CI/CD pipelines

The CLI delivers professional-grade output with color-coded insights, formatted tables, and rendered Markdown—making complex analysis instantly readable in your terminal.

![CLI Startup](cli-entry.png)

```bash
# Interactive mode (session management enabled)
uv run cli.py

# Direct query mode
uv run cli.py "What are the top 5 gainers last week?"

# Custom date range
uv run cli.py "Analyze RELIANCE from 2024-01-01 to 2024-12-31"

# Pattern detection
uv run cli.py "Find stocks with volume surge and high delivery percentage"

# Comparison
uv run cli.py "Compare TCS, INFY, and WIPRO on risk metrics"
```

**Interactive Mode Features**:

- **Rich-powered interface**: Beautiful tables, syntax highlighting, progress spinners
- **Session persistence**: Resume conversations from previous runs
- **Real-time feedback**: Live tool execution status with animated spinners
- **Token tracking**: See API costs after each query
- **Session switching**: Type `switch` to browse and resume past sessions
- **Commands**:
  - `switch` - Browse and switch between sessions
  - `clear` - Clear current session history
  - `exit` / `quit` / `bye` - Save session and exit

**How it works**:

1. Agent loads data from Parquet cache (downloaded from GitHub on first run)
2. Processes query through 5-agent pipeline with event compaction
3. Displays beautifully formatted report with Rich library
4. Tracks tokens/cost and saves session to SQLite database
5. Session persists—resume anytime by selecting from session list

### Option 3: Docker Deployment

#### Quick Start with Docker

**1. Build the Docker image:**

```bash
docker build -t investor-paradise:latest .
```

**3. Run with Docker CLI:**

```bash
# Web mode (ADK web server)
docker run --rm -e GOOGLE_API_KEY="your_api_key" -p 8000:8000 investor-paradise

# CLI mode (interactive terminal)
docker run --rm -it -e GOOGLE_API_KEY="your_api_key" investor-paradise cli
```

#### Environment Variables

| Variable | Required | Default | Description |
|----------|----------|---------|-------------|
| `GOOGLE_API_KEY` | ✅ Yes | - | Your Google AI API key |
| `SESSION_CLEANUP_DAYS` | ❌ No | 7 | Delete sessions older than N days |

#### Container Logs

```bash
# View real-time logs
docker-compose logs -f

# View specific container logs
docker logs investor-paradise-agent

# Check health status
docker inspect investor-paradise-agent | grep -A 5 Health
```

#### Stopping the Agent

```bash
# Stop container (if running with -d flag)
docker stop investor-paradise
docker rm investor-paradise
```

#### Production Deployment

For production environments:

1. **Use named volumes** (instead of bind mounts) for better performance:

   ```yaml
   volumes:
     - cache-data:/app/investor_agent/data/cache
     - session-data:/app/investor_agent/data
   ```

2. **Enable resource limits** in `docker-compose.yml`:

   ```yaml
   deploy:
     resources:
       limits:
         cpus: '2.0'
         memory: 4G
   ```

3. **Set up reverse proxy** (e.g., nginx) for SSL/HTTPS
4. **Configure monitoring** (Prometheus + Grafana)
5. **Set up backup** for `sessions.db` and cache files

---

### Option 4: ☁️ Google Cloud Deployment (Vertex AI Agent Engine)

**Best for**: Production deployment, scalable cloud hosting, enterprise usage

We've successfully deployed **Investor Paradise** to Google Cloud's **Vertex AI Agent Engine** using the official [agent-starter-pack](https://github.com/GoogleCloudPlatform/agent-starter-pack). This provides a fully managed, serverless deployment with auto-scaling and built-in monitoring.

#### 🎯 Key Benefits

- ✅ **Serverless**: No infrastructure management, auto-scales based on traffic
- ✅ **Managed**: Google handles deployment, monitoring, and updates
- ✅ **Secure**: Uses Google Cloud's Application Default Credentials (no API keys in code)
- ✅ **Cost-effective**: Pay only for actual usage (no idle server costs)
- ✅ **Integrated**: Works with Vertex AI Agent Playground for testing

#### 📦 Deployment Architecture

```bash
investor_paradise/
├── investor_agent/          # Packaged and deployed to Cloud Run
│   ├── agent.py            # Auto-detects cloud env (K_SERVICE variable)
│   ├── data_engine.py      # Loads data from GCS bucket
│   └── cache_manager.py    # Downloads data on container startup
├── .gcloudignore           # Excludes large data files (>8MB limit)
└── deployment/
    ├── agent_engine_config.yaml  # Vertex AI configuration
    └── Dockerfile.agent-engine   # Container definition
```

**Smart Environment Detection**: The agent automatically detects deployment environment:

## Troubleshooting

### Cache Download Issues

**Problem**: Cache files fail to download from GitHub releases  
**Solution**:

- Check your internet connection
- Verify GitHub is accessible from your network
- If behind a corporate firewall, you may need to configure proxy settings
- Try manually downloading cache files from [investor_agent_data releases](https://github.com/atulkumar2/investor_agent_data/releases)

**Problem**: "Cache files not found" error  
**Solution**:

- Run `uv run cli.py --refresh-cache` to force re-download
- Ensure you have write permissions to `investor_agent/data/cache/` directory
- Check if cache files exist in `investor_agent/data/cache/` (should see 4 `.parquet` files)

**Problem**: Slow first-time startup  
**Solution**: First run downloads ~50MB of cache files from GitHub. This is a one-time process. Subsequent runs will be instant.

### Data Loading Issues

**Problem**: "No data loaded" when starting agent  
**Solution**:

1. Check if cache files exist in `investor_agent/data/cache/`
2. Try refreshing cache: `uv run cli.py --refresh-cache`
3. Verify all 4 cache files are present:
   - `combined_data.parquet`
   - `nse_indices_cache.parquet`
   - `nse_sector_cache.parquet`
   - `nse_symbol_company_mapping.parquet`

**Problem**: Agent queries return "No data available for [dates]"  
**Solution**: The cache contains data from the [investor_agent_data repository](https://github.com/atulkumar2/investor_agent_data). If you need different date ranges, check the data repository for updates or contribute new data.

**Problem**: Outdated stock data  
**Solution**: Run `uv run cli.py --refresh-cache` to download the latest cache from GitHub releases. Data is updated periodically in the [investor_agent_data repository](https://github.com/atulkumar2/investor_agent_data).

## Advanced Configuration

### Custom Data Path

```python
# investor_agent/data_engine.py
NSESTORE = NSEDataStore(root_path="path/to/custom/data")
```

### Tool Organization (Modular Structure)

Tools are now organized in `investor_agent/tools/` for better maintainability:

- **indices_tools.py** (9 tools): Index constituents, market cap classification, **sector+cap filtering**
  - `get_index_constituents()`, `list_available_indices()`, `get_stocks_by_market_cap()`
  - `get_stocks_by_sector_and_cap()` ⭐ **NEW**: Filter by both sector AND market cap
- **core_analysis_tools.py** (6 tools): Market scans, stock analysis, comparisons
  - `get_top_gainers()`, `analyze_stock()`, `compare_stocks()`, etc.
- **advanced_analysis_tools.py** (9 tools): Pattern detection, risk metrics
  - `detect_breakouts()`, `find_momentum_stocks()`, `analyze_risk_metrics()`, etc.
- **semantic_search_tools.py** (2 tools): PDF news database search
  - `get_company_name()`, `semantic_search()`

Import all tools via:

```python
from investor_agent.tools import get_top_gainers, analyze_stock, get_stocks_by_sector_and_cap, ...
```

### Sector Mapping

Sector-to-symbol mapping now uses CSV (`investor_agent/data/sector_mapping.csv`) instead of hardcoded dictionaries for easier updates.

### Model Selection

```python
# investor_agent/agent.py
root_agent = create_pipeline(
    model,                    # Flash-Lite for Entry/News
    market_model=flash_model, # Flash for Market (tool-heavy)
    merger_model=pro_model    # Pro for Synthesis
)
```

### Cache Management

```bash
# Clear Parquet cache to force CSV reload
rm -rf investor_agent/data/cache/combined_data.parquet
```

### Session Management

```bash
# View all sessions
sqlite3 investor_agent/data/sessions.db "SELECT user_id, session_id, created_at FROM sessions;"

# Delete old sessions manually
sqlite3 investor_agent/data/sessions.db "DELETE FROM sessions WHERE created_at < date('now', '-30 days');"

# Reset all sessions (caution: deletes all history)
rm investor_agent/data/sessions.db
```

### Logging

```python
# investor_agent/logger.py
logger = get_logger(__name__)
logger.info("Custom log message")

# View logs
tail -f logger.log
```

### Performance Tuning

```bash
# Force Parquet cache rebuild
rm -rf investor_agent/data/cache/combined_data.parquet

# Check cache size
du -sh investor_agent/data/cache/

# View token usage statistics from logs
grep "Token Usage" cli.log | tail -10
```

## Linting & Formatting

```bash
# Check code quality
ruff check .

# Auto-format code
ruff format .
# or
black .
```
