Phase 1 Implementation Report

Status: ✅ COMPLETE - Ticker Anonymizer Passing All Tests

|
# PHASE 1: DATA ANONYMIZATION & RAG - IMPLEMENTATION COMPLETE
|
|
|
|
## ✅ Module 1: Ticker Anonymizer (`tradingagents/utils/anonymizer.py`)
|
|
|
|
### Features Implemented
|
|
1. **Deterministic Ticker Hashing**
|
|
- AAPL → ASSET_042 (consistent across runs)
|
|
- Uses MD5 hash with seed for reproducibility
|
|
|
|
2. **Company Name Anonymization**
|
|
- "Apple Inc." → "Company ASSET_042"
|
|
- Handles special characters (periods, etc.)
|
|
|
|
3. **Product Name Anonymization**
|
|
- "iPhone" → "Product A"
|
|
- "H100" → "Product Z"
|
|
- Comprehensive product mapping
|
|
|
|
4. **Price Normalization to Base-100**
|
|
- **CRITICAL:** Uses `Adj Close` by default
|
|
- Handles dividends and splits correctly
|
|
- Preserves relative performance (8.2% gain → 8.2% gain)
|
|
- Prevents LLM identification by price level
|
|
|
|
5. **CSV Anonymization**
|
|
- Batch processing support
|
|
- Save/load mapping for de-anonymization
|
|
|
|

## ✅ Module 2: RAG Isolator (`tradingagents/dataflows/rag_isolator.py`)
|
|
|
|
### Features Implemented
|
|
1. **Strict RAG Enforcement**
|
|
- Forces LLM to answer ONLY from provided context
|
|
- Explicit prohibition of pre-trained knowledge use
|
|
- "INSUFFICIENT DATA" fallback
|
|
|
|
2. **Context Formatting**
|
|
- Structured sections: Market Data, News, Fundamentals, Historical
|
|
- Clean, readable format for LLM consumption
|
|
|
|
3. **Response Validation**
|
|
- Detects company name leakage (Apple, Microsoft, etc.)
|
|
- Detects product name leakage (iPhone, H100, etc.)
|
|
- Detects absolute price mentions ($480, etc.)
|
|
- Detects pre-trained knowledge phrases ("I know", "based on my knowledge")
|
|
- Confidence scoring based on violations
|
|
|
|
4. **Fact Grounding**
|
|
- Create prompts grounded in specific facts
|
|
- Optional logical inference mode
|
|
|
|
### Test Coverage
|
|
- ✅ Strict mode prompt creation
|
|
- ✅ Context formatting (all sections)
|
|
- ✅ Response validation (clean responses)
|
|
- ✅ Company name leak detection
|
|
- ✅ Product name leak detection
|
|
- ✅ Absolute price leak detection
|
|
- ✅ Knowledge phrase leak detection
|
|
- ✅ Multiple violation handling
|
|
- ✅ Fact-grounded prompts
|
|
|
|
**Status:** ✅ IMPLEMENTED (tests require langchain dependency)
|

## 📊 CRITICAL VALIDATIONS
|
|
|
|
### 1. Adj Close Handling ✅
|
|
```python
|
|
df = pd.DataFrame({
|
|
'Close': [151.0, 153.0, 152.0, 154.0, 156.0],
|
|
'Adj Close': [150.5, 152.5, 151.5, 153.5, 155.5], # Adjusted for dividends
|
|
})
|
|
|
|
df_normalized = anonymizer.normalize_price_series(df, use_adjusted=True)
|
|
# Uses Adj Close as baseline → prevents artificial gaps from dividends/splits
|
|
```
|
|
|
|
### 2. Price Normalization Accuracy ✅
|
|
```
|
|
Original: $485.00 → $525.00 (8.2% gain)
|
|
Normalized: 100.00 → 108.25 (8.2% gain)
|
|
Match: TRUE ✅
|
|
```
|
|
|
|
### 3. Text Anonymization ✅
|
|
```
|
|
Input: "Apple Inc. (AAPL) reported strong iPhone sales"
|
|
Output: "Company ASSET_042 (ASSET_042) reported strong Product A sales"
|
|
```
