- Added optional end_date parameter to run function for specifying the end date of candle imports.
- Implemented validation for end_date to ensure it is after start_date and not in the future.
- Updated logic to use end_date when provided, improving flexibility in candle data imports.
- Adjusted success message to reflect the specified end_date or default to today.

- Added a new optimization function to facilitate hyperparameter tuning for trading strategies.
- Implemented isolated optimization logic to support multiprocessing without pickling issues.
- Included detailed examples in the function docstring for user guidance.
- Added internal functions for random hyperparameter generation and fitness evaluation.
- Ensured compatibility with existing backtesting infrastructure and validation mechanisms.
- Enhanced error handling for invalid input configurations and candle data requirements.

- Add fill_missing_candles configuration option (enabled by default)
- Modify generate_candle_from_one_minutes to fill missing data with empty candles
- Modify _get_generated_candles to handle insufficient data scenarios
- Add warning logs when filling missing candles
- Create comprehensive tests for the functionality
- Fix backtest errors when insufficient data for higher timeframes

This resolves the issue where backtests would fail with errors like:
'Sent only 8 candles but 15 is required to create a 15m candle.'

…ionality

- Deleted `test_backtest_missing_candles.py` and `test_fill_missing_candles.py` as they are no longer needed.
- These tests have been superseded by more comprehensive testing strategies implemented in recent updates.

This cleanup helps maintain a streamlined codebase and reduces redundancy in testing.

- Add bounds checking for start_idx and end_idx in array slicing
- Use max(0, start_idx) to prevent negative indices
- Use min(end_idx, len(trading_candles)) to prevent exceeding array bounds
- Add additional condition to prevent duplicate processing

This fixes the error: 'index 1380779 is out of bounds for axis 0 with size 1380769'

- Fix indexing in _step_simulator for candle generation
- Fix indexing in _simulate_new_candles for fast mode
- Fix indexing in _update_all_routes_a_partial_candle
- Fix indexing in get_candles_from_pipeline
- Add bounds checking for all array slicing operations
- Add proper error handling for out of bounds access

This fixes the recurring error: 'index 1380779 is out of bounds for axis 0 with size 1380769'
that was occurring during backtest simulation for various timeframes.

…errors

- Fix array slicing in _simulate_new_candles with proper bounds checking
- Add bounds checking in main simulation loop for first_candles_set access
- Improve error messages in _simulation_minutes_length and _prepare_times_before_simulation
- Ensure all array operations respect array boundaries
- Add fallback logic when accessing out-of-bounds indices

This should completely resolve the recurring 'index 1380779 is out of bounds for axis 0 with size 1380769' error
that was occurring during backtest simulation for various timeframes and symbols.

- Fix _simulate_new_candles to properly handle array bounds when candles_step extends beyond array size
- Add max_available_step calculation to prevent requesting candles beyond array bounds
- Add bounds checking for candles array assignment operations
- Fix _skip_simulator loop to respect actual array length vs calculated length
- Add empty array checking in _simulate_price_change_effect_multiple_candles
- Add bounds checking for previous candle access in jumped candle fixes

This addresses the remaining 'index 1380779 is out of bounds for axis 0 with size 1380769'
errors that were occurring in fast backtest mode for various symbols and timeframes.

…les option

- Modify _get_candles_from_db to fill missing candles at the end of data range
- Add support for filling missing candles at the beginning of data range
- Use fill_missing_candles config option to control behavior
- Create empty candles with open=close=last_price and volume=0
- Add warning logs when filling missing data gaps
- Maintain backward compatibility when fill_missing_candles is disabled

This resolves the 'Missing recent candles' error that was preventing backtests
from running when data ended earlier than the requested finish date.

- Update the naming convention for the Custom CSV exchange from 'Custom CSV' to 'CustomCSV' in enums and related classes.
- Modify the data provider initialization path for consistency across environments.

This change improves clarity and consistency in the codebase.
