* Fix performance degradation on expirying assets
- Options would expire and get removed, when the universe removed the
security it would never be reseted on universe selection, causing
leaks
- Minor improvement for composer assembly loading
- Minor improvement for loading exception interepreters, so it uses
composer
* Minor regression test fix
* Add new benchmark algorithm

* Use Futures Bank Holidays For Expirations
* Minor improvements
- Futures will be stored by their contract month, not expiry
* Delete dairy future products
* Minor test fixes
* Add optional strict parameter to PivotPointsHighLow indicator for relaxed comparison
- Added bool strict parameter (default true) to PivotPointsHighLow constructors
- When strict=true: Uses strict inequalities (> and <) - existing behavior
- When strict=false: Uses relaxed inequalities (>= and <=) - allows equal values
- Updated comparison logic in FindNextLowPivotPoint and FindNextHighPivotPoint
- Added new PPHL overload in QCAlgorithm.Indicators.cs with strict parameter
- Added 5 comprehensive unit tests using TestCase attributes
- All tests pass (19/19 relevant tests)
- Backwards compatible: default behavior unchanged
Addresses #8881
* Fix PPHL method signature to resolve overload ambiguity and maintain API consistency
- Remove wrapper overload to eliminate compilation ambiguity
- Reorder parameters: strict parameter now before resolution
- Keep selector as last parameter (consistent with other indicator helpers)
- Add unit tests verifying no overload ambiguity and correct strict parameter behavior
Addresses PR review feedback on #9033
* Implement backward-compatible PPHL overloads to support strict parameter
Added a second overload to maintain backward compatibility while introducing
the strict parameter. This prevents breaking changes for existing code that
uses positional arguments with the PPHL helper method.
Changes:
- Added backward-compatible overload that accepts (symbol, lengthHigh, lengthLow,
lastStoredValues, resolution, selector) and delegates to the new implementation
with strict: true
- Kept the new overload with strict parameter as the primary implementation
- Added comprehensive test (QCAlgorithmHelperOverloadResolution) documenting all
9 valid call patterns to prevent future regressions
This approach ensures:
- Existing calls like PPHL(symbol, 3, 3, 100, Resolution.Minute) continue to work
- New calls like PPHL(symbol, 3, 3, strict: false) are supported
- No ambiguity in overload resolution
- All 23 PPHL tests pass successfully
* Clean up some test duplication
