From 109dd8663ddc7d2259fa282fe2606a7464bda5e5 Mon Sep 17 00:00:00 2001 From: Jeff West Date: Tue, 16 Sep 2025 05:02:16 -0500 Subject: [PATCH 1/2] feat: Add batch operations for multi-symbol data fetching - Update history.py to support multi-symbol bars with automatic batching for 200+ symbols - Update latest_quote.py to support batch quotes with automatic batching - Implement concurrent request handling using ThreadPoolExecutor - Add comprehensive tests (20 test cases: 11 unit, 9 integration) - Update README with batch operation examples and features - Optimize DataFrame operations for better performance - Maintain backward compatibility for single-symbol requests -
