- Adding new DataPermissionManager that will own the existing
datachannelProvider. Will assert configurations before added to the
data feed. Adding unit tests
- Fix out of range exception, if the returns array is smaller for some
of the Symbols it will use double.NaN, similar behavior to when a date
isn't found for a Symbol. Adding unit test
- Fix duplicate key exception at ReturnsSymbolData.Returns, this could
happen with FF in history requests. Adding unit test
- Remove unrequired symbol check
- Dispose of `ZipDataCacheProvider` used in unit tests.
To avoid issues with other tests since zip files could remain open.
When new securities are added to the universe, the `ReturnsSymbolData` is warmed up with historical data that may not have the same timestamp causing an index mismatch that leads to a rejection to several valid data. In this case, we will assume that there is a time correspondence similar to what is done in Python. Unit test was added.
`BlackLittermanOptimizationPortfolioConstructionModel` will consider a new view only if there is a new last active insight by updating the `ReturnsSymbolData` with the `Insight.GeneratedTimeUtc` instead of the `IAlgorithm.Time`. Consequently, the timestamp of the historical data is converted to UTC for consistency.
`BlackLittermanSymbolData` now rejects duplicate keys like its C# version: `ReturnsSymbolData`.
Finally, `BlackLittermanPortfolioOptimizationFrameworkAlgorithm` statistics was updated because of the bug fixes.
Update test to the new crypto and equity subscriptions rules:
- Only consolidates trades
- Low resolution data are only trades.
Update and fix tests
Add missing minute sample files
Update Regression algorithms statistics
Crypto and Equities will consolidate trades by default
Daily and hourly resolution will return only trades for crypto and equities.
Update equity TAQ regression test
Add minute sample files
Updating regression algorithms
Update SpotMarket test cases
Add regression test for equity trades and quotes
- History request.
- Trades and quotes pumped into OnData.
- Subscriptions are added correctly.
Add sample data
Checks low resolution only subscribes to trade bars
- MeanVarianceOptimizationPortfolioConstructionModel tests will use
`SingleEntryDataCacheProvider`, instead of `ZipDataCacheProvider`, so
that zip files are not cached into memory and block other usages
Implements `PortfolioBias` in EWPCM, CWPCM and IWPCM. With this new feature, these PCM will ignore insights that do not respect the desired bias. E.g. for `PortfolioBias.Long`, on Insights with `InsightDirection.Up` will be converted into `PortfolioTarget.Quantity` greater than zero and other `InsightDirection` will result in `PortfolioTarget.Quantity` of zero.
- Adding new unit test for python PCM implementations, asserting each
method is correctly called
- Reverting some unrequired changes in the
`MeanVarianceOptimizationFrameworkAlgorithm`
- Refactor AccumulativeInsightPortfolioConstructionModel to inherit from
the EWPCM, reducing code duplication and adding support for rebalancing
period
- Fixing bug where only 1 new insight per symbol was processed per loop
- Adding unit tests
- Adding new `Func<DateTime, DateTime?>` that allows PCM to return null
if the next rebalance time is null, in which case the function will be
called again in the next loop.
- Adjusting PCM next rebalance time check to perform rebalance once the
time is reached
- Adding new regression test. Updating existing
- Moving InsightCollection into base `PortfolioConstructionModel`
- Will call `InsightCollection.GetNextExpiryTime()` on each check, and
for performance `InsightCollection` will keep track of next insight
expiry time
- Removing need for PCM base classes having to call `RefreshRebalance`
- Some refactor clean up at base
PortfolioConstructionModel.IsRebalanceDue()
- Refactoring some PCM methods to be `protected` since they are not required
to be public
- Adding new `PortfolioConstructionModel.RebalanceOnInsightChanges`
flag, that will allow avoiding new insights or insight expirations to
trigger a rebalance
- Updating unit tests
- Fix for the MeanVarianceOptimizationPortfolioConstructionModel that
was skipping, in some cases, 0 magnitude insights
- Improving OrderSizing.Value and Volume to include code in consumers
- OrderSizing.GetUnorderedQuantity() will adjust result by lot size
- ImmediateExecutionModels will use OrderSizing.GetUnorderedQuantity()
- OrderSizing.Value() will take into account ContractMultiplier
- Adding unit tests
- Add missing PCM constructor methods for the different supported
rebalancing periods overloads
- Normalize rebalance behavior in the base `PortfolioConstructionModel`
- Adding new `PortfolioConstructionModel.RebalanceOnSecurityChanges`
that will allow disabling rebalance on security changes
- Adding unit tests
