Batch LLM API Optimization

[iAmGiG]

Feature Request: Batch LLM API Processing

Problem

Current system makes individual LLM calls per trading day. For large date ranges, this is:

• Inefficient (many API calls)
• Expensive (per-call costs add up)
• Slow (network latency per call)

Proposed Solution

Batch process multiple days in single LLM call:

• Group by week (5 trading days)
• Send all week's GEX data in one prompt
• Get batch analysis response
• Parse responses back to individual days

Example Batch Prompt

Analyze the following 5-day trading sequence:

Day 1 (2024-01-02): GEX=-5.3B, regime=NEGATIVE_GAMMA_LOW...
Day 2 (2024-01-03): GEX=-8.9B, regime=NEGATIVE_GAMMA_LOW...
Day 3 (2024-01-04): GEX=+2.1B, regime=POSITIVE_GAMMA_LOW...
...

Provide WHO/WHOM/WHAT analysis for each day.

Benefits

• Reduce API calls by 5x (weekly batches)
• Lower costs through bulk processing
• Faster execution (fewer network round trips)
• LLM can see day-to-day context patterns

Implementation Notes

• Need robust response parsing
• Handle batch failures gracefully
• Maintain individual day result format
• Test with different batch sizes (3, 5, 10 days)

Priority

Medium - Would significantly improve efficiency for large-scale testing

✅ Batch LLM API Optimization - IMPLEMENTED

The batch LLM processing system has been fully implemented as part of the continuous experiment framework!

🎯 All Requirements Met

✅ Reduce API calls by 5x (weekly batches)

• Implemented in src/llm/batch_processor.py
• Groups 5 trading days per LLM call (configurable batch size)
• 80% reduction in API calls vs individual day processing

✅ Weekly batch processing with context

• prepare_batch_analysis() method processes entire date ranges in weekly chunks
• LLM sees day-to-day context patterns for better analysis

✅ Robust response parsing

• _parse_batch_response() extracts individual day analyses from batch JSON
• Validates all required fields: signal_type, confidence, reasoning
• Handles various response formats (plain JSON, markdown code blocks)

✅ Graceful batch failure handling

• 3-tier fallback: Batch → Individual LLM call → Neutral analysis
• Failed batches tracked and retried with individual calls
• No data loss from batch processing failures

🚀 Enhanced Beyond Original Request

Advanced Features Delivered:

• WHO/WHOM/WHAT Analysis: Each day gets full market mechanics analysis
• Confidence Calibration: Structured confidence levels (0.0-1.0)
• Checkpoint Integration: Batch preparation state saved for resumption
• Performance Tracking: API call reduction and success rate monitoring

📁 Implementation Files

Core System:

• src/llm/batch_processor.py - Main batch processing engine
• docs/architecture/data_architecture.md - Integration documentation

Key Methods:

# Prepare entire date range in weekly batches
batch_results = processor.prepare_batch_analysis(start_date, end_date, symbol, market_data, gex_data)

# Get analysis with fallback strategy
analysis = processor.get_day_analysis(date, market_data, gex_data, symbol)

# Monitor performance
stats = processor.get_batch_statistics()

🎯 Example Batch Prompt Format (Implemented)

Analyze the following 5-day trading sequence:

Day 1 (2024-01-02):
- Price: $475.32
- GEX: -5,300,000,000
- Regime: NEGATIVE_GAMMA_LOW
- Options Volume: 1,234,567

Day 2 (2024-01-03): ...

Provide JSON analysis for each day with WHO/WHOM/WHAT mechanics.
