Add verbose parameter to TvDatafeed for controlling log verbosity. This allows production deployments to have clean logs while maintaining detailed logging for development. Features: - NEW: verbose parameter in TvDatafeed.__init__() - Environment variable support: TV_VERBOSE - Priority: parameter > env var > default (True) - Errors and warnings always shown regardless of verbose setting - Backward compatible: verbose=True by default Files modified: - tvDatafeed/main.py: Added verbose parameter and logging control - README.md: Added "Verbose Logging" documentation section - examples/quiet_mode.py: Complete example with 5 use cases - tests/unit/test_main.py: 13 new tests for verbose functionality - .env.example: Added TV_VERBOSE configuration - CHANGELOG.md: Documented the new feature Tests: 13 new tests, all passing Upstream: Based on PR rongardF#37 from rongardF/tvdatafeed
Add date range search capability allowing users to fetch historical data
by specifying start/end dates instead of just n_bars. This is a major
feature for backtesting and quantitative analysis workflows.
Features:
- NEW: start_date and end_date parameters in get_hist()
- Support for both datetime objects and Unix timestamps
- Timezone-aware DataFrames with metadata in attrs
- Robust validation: no future dates, start < end, after 2000-01-01
- Mutually exclusive with n_bars parameter (validated)
- interval_len dictionary mapping all intervals to seconds
- Backward compatible: n_bars still works as default
Core Implementation:
- tvDatafeed/main.py:
* Added interval_len dictionary (13 intervals)
* New is_valid_date_range() static validation method
* Extracted __get_response() to consolidate WebSocket reading
* Enhanced __create_df() with interval_len and time_zone params
* Extended get_hist() signature with start_date/end_date
* Date range format: "r,{start_timestamp}:{end_timestamp}"
* TradingView API adjustment: -1800000ms (30min)
- tvDatafeed/validators.py:
* New validate_date_range() for comprehensive validation
* New validate_timestamp() supporting seconds/milliseconds
* Clear DataValidationError messages
Documentation:
- README.md: New "Date Range Search" section with examples
- examples/date_range_search.py: 350+ lines, 5 complete use cases
- CHANGELOG.md: Detailed feature documentation
Testing:
- 16 new unit tests, all passing (100% pass rate)
- Tests cover: validation, mutual exclusivity, timezones, edge cases
- Backward compatibility verified with existing tests
Quality:
- Type hints on all new methods
- Numpy-style docstrings with examples
- No breaking changes - 100% backward compatible
- Follows existing code patterns and standards
Tests: 16 new tests, all passing
