* Add DualSymbolIndicator unit tests
* Introduce MultiSymbolIndicator for indicators working on multiple symbols
Use the new class as base for DualSymbolIndicator and OptionIndicatorBase.
The OptionIndicatorBase can now detect when ready even if underlying and options market close is different when resolution is daily.
* Accept any BaseData for options indicators
* Improve indicator conversion from python on registration
Also minor fixes
* Cleanup and simplification
* Fix ImpliedVolatility IsReady flag
* Update regression algorithm history count
AutomaticIndicatorWarmupOptionIndicatorsMirrorContractsRegressionAlgorithm history count decreased because options indicators period is now 1 instead of 2
* Address peer review
* WIP: Refactor Correlation Indicator
* Simplified comparison logic and improved abstraction
* Refactor Correlation and Beta indicators
- Created a base class to handle indicators with dual-symbol
functionality.
- Refactored the Beta and Correlation indicators to inherit from the new
base class.
- Updated unit tests.
- Added a new regression test to validate the latest computed value.
* Addressed review comments
* Update regression test
* Add new unit test to CommonIndicatorTests
* Addressed new review comments
* Fix bug in beta calculation
- Beta is fill-forwarded
- A correct pair considered when they have different symbols and the
same date
- Processing occurs when there are at least period+1 correct pairs
* Address review comments
* Add time zone handling and resolution-based truncation
* Fix regression test for Beta indicator
* Handle resolution for beta indicator
- Remove effectiveResolution and Beta constructor parameter for
resolution.
- Streamlined resolution handling logic for Beta indicator.
- Fixed issues with regression test for Beta.
* Fix issue with period and WarmUpPeriod
* Update unit tests for Alpha indicator
* Fixing minor issues
* Add a variable to track if the previous symbol is the target
* Add regression test for Beta calculation between BTCUSD and SPY
* Add an extra period if the TZ are different
Adds a new constructor overload that matches the pattern in Lean: Symbol, Symbol, other types.
Adds a new constructor that infers the indicator name: "B(period)".
