Registering an indicator or consolidator for a symbol that had not been
subscribed to threw 'Please register to receive data for symbol ...'.
Order submission already auto-subscribes the symbol on the user's behalf;
this applies the same behavior to indicator/consolidator registration.
GetSubscription now adds the security automatically when it has no
subscription (guarded by the shared CanAutoAddSecurity check, which is
also used by order submission) before falling back to the error. The
subscription lookup is exposed via a TryGetSubscription out-parameter
helper.
Implement WaveTrendOscillator (bar indicator) per the linked issue. Adds
the indicator class, the WTO helper in QCAlgorithm.Indicators.cs, unit
tests inheriting CommonIndicatorTests<IBaseDataBar>, and the reference
CSV under Tests/TestData/.
The oscillator is computed from the typical price (HLC/3): an EMA
smooths it (ESA), a second EMA tracks its absolute deviation (D), the
normalized channel index (HLC3 - ESA) / (0.015 * D) is smoothed by a
third EMA to produce WT1, and an SMA of WT1 produces the signal line
WT2. Crossovers between WT1 and WT2 are commonly used as entry and exit
signals for momentum reversals.
Reference values were generated with TA-Lib (talib.EMA + talib.SMA)
following the script posted by @LouisSzeto in the issue thread.

* Implements Covariance as Lean Indicator
* Add COV helper method and fix AcceptsVolumeRenkoBarsAsInput test
* Fix AcceptsRenkoBarsAsInput test to use smaller period for faster execution
* Fix slow Renko tests by limiting data processed to 50 rows
* 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
