…han data timeframe (#396) - Add validation in TradingStrategy.__init__ that compares the strategy's scheduling interval (time_unit * interval) against the smallest OHLCV data source timeframe. Raises OperationalException with a descriptive message if the interval is too fast. - Add 7 tests in tests/app/test_strategy_interval_validation.py covering all edge cases (faster, equal, slower, multiple sources, no sources, non-OHLCV sources, error message content). - Fix test strategies in test_data_completeness.py that had invalid 1-minute intervals with 1-day OHLCV data.

Summary
Closes #396
Raises
OperationalExceptionduringTradingStrategy.__init__when the strategy's scheduling interval is faster than the smallest OHLCV data source timeframe.Changes
investing_algorithm_framework/app/strategy.py— Added validation that computes the scheduling interval (time_unit.amount_of_minutes * interval) and compares it against the smallest OHLCV data source timeframe. Raises a descriptiveOperationalExceptionif the interval is too fast.tests/app/test_strategy_interval_validation.py(new) — 7 test cases covering: raises on too-fast interval, accepts matching/slower intervals, validates against smallest OHLCV source, skips when no OHLCV sources, skips non-OHLCV sources, and checks the error message.tests/app/test_data_completeness.py— Fixed test strategies that had invalid 1-minute intervals with 1-day OHLCV data (updated to DAY).Example error message
