A new IBrokerageCashSynchronizer interface has been added to allow brokerage implementations to handle the cash sync process. Most of the cash sync logic has been moved from the BrokerageTransactionHandler to the base Brokerage class.
The IB brokerage will not attempt to perform cash sync during server reset times, respecting the different regional schedules (see also #3413).
Adds `DuplicateKeyPortfolioConstructionModelTests` to evaluate duplicate keys exception on `ReturnsSymbolData.FormReturnsMatrix` method.
Removes `DuplicateKeyExceptionAlgorithm` as it is replaced by the unit test.
In order to provide full Lean Indicator functionality to python custom indicators, they need to inherit from a C# class. `PythonIndicator` will serve for this purpose.
Algorithms can use the former version (no inheritance).
In order to add support custom python indicators for `QCAlgorithm.PlotIndicator`, we created a `PythonIndicator` class that wraps the custom python indicator. In `QCAlgorithm`, the reference of the wrapper is saved into a dictionary keyed by the python indicator handle.
- Adding new `AlgorithmSettings` Min and Max absolute portfolio target
percentage
- Adding new `PortfolioConstructionModel.FilterInvalidInsightMagnitude()`
helper method that will be used by the `BlackLitterman` and
`MeanVariance` optiomization portfolio construction models to skip
insights with extreme magnitudes that will cause exceptions
- `PortfolioTarget.Percentage()` will now verify requested percent is
withing the settings values
- For backtesting the algorithm thread will sequentially process pending
order requests
- Adding new non blocking `BusyCollection`
- Updating `UpdateOrderRegressionAlgorithm` that suffered of a race
condition: it supposed `OnOrderEvent` would be called after the call to
`Transactions.AddOrder()` was finished
- `Alpha Assets` chart will only store last data point
- Adding new `JsonRoundingConverter` that will round to 4 (number of
digits currently used for comparing alpha statistics) fractional
digits.
- Will be used for `Insights` and `ChartPoint`
- Adding new `InsightWeightingPortfolioConstructionModel` that will
generate percent `Targets` based on the latest active `Insight` `Weight` per
`Symbol`.
- Will ignore `Insights` that have no `Weight`.
- If the sum of all the last active `Insight` per `Symbol` is bigger than 1, it
will factor down each target percent holdings proportionally so the sum is 1.
- Adding unit tests
- Adding a new regression test framework algorithm
- Note most of the code, including tests, are reused from the
`EqualWeightingPortfolioConstructionModel`
This model was assuming that the history request used to warm up the indicators contains the 'close' column which is only valid for Equity.
The models were also refactored to update the indicators without a consolidator since the last data point from the history request was not pushed throught the indicators.
Implements `DataNormalizationMode` field in `UniverseSettings` to enable the settings of a desired `DataNormalizationMode` to the securities that are chosen in Universe Selection.
Adds unit tests for UniverseSelectionModel's that can be used to create new models with inheritance:
- ManualUniverseSelectionModel
- FundamentalUniverseSelectionModel
- Adding new `CompositeAlphaModel.AddAlphaModel()`
- Adding C#/Py regression algorithms using the new `QCAlgorith.AddAlphaModel()`
- Improving exception message
- Add python version of `QCAlgorith.AddAlphaModel()`
- Removing `using QCAlgorithmFramework = QuantConnect.Algorithm.QCAlgorithm`
- Removing `QCAlgorithmFrameworkBridge`
- Removing `IsFrameworkAlgorithm`
- Making `EmitInsightBasedOnFill` private. Adding new
`IOrderEventProvider` exposing an `event` to which `QCAlgorithm` will
subscribe.
- `AccountType.Cash` algorithms will be allowed to manually trade and
emight insights manually or with alpha model.
Implement a new overload to `Insight` constructor that accepts a `Func<DateTime, DateTime>` that is used to compute the `CloseTimeUtc` and `Period` after the `Insight` object is emitted (`SetPeriodAndCloseTime` method).
Adds the static Expiry class with functions that can be used to compute a future date/time (expiry) given a date/time.
Closes#3038
- Classic Algorithms will emight insights based on order fills.
- To be able to update generated insights closed time, we will not
clone emitted insights.
- `InsightAnalysisContext` will update `AnalysisEndTimeUtc` when the
Insight period is closed and the period is `EndOfTimeTimeSpan`
- Adding new regression algorithm asserting on the new emitted insights
- Adding unit tests
- `LiveTradingResultHandler` will store `AlphaRunTimeStatistics`
- Making `DefaultAlphaHandler.ProcessAsynchronousEvents` virtual to
facilitate cloud changes
- Removing OrderFeeParameters.AccountCurrency. Where required replacing
for constructor parameter defaulting to USD.
- Updating IB fee model to use to correct fee currency
- `GetCashBalance()` will return a `List<CashAmount>`, will not need to
set conversion rates, which requires knowing what the account currency is.
- Removing `Global.Holding` conversion rate field. It wasn't being used
and required knowing what the account currency is.
- Adding equality operators for `CashAmount`. Adding unit tests.
- `CashBook[NullCurrency] { get; }` will throw an exception
- Revert `Currencies.USD` changes in user facing algorithms
- Improve some documentation
- Revert some format changes
- Adding more asserts for regression test
- Adding new regression tests using a custom fee model which returns
`OrderFee.Zero`
- Adding a non-usd account currency test to the cash book tests
- Adding some unit tests for `NullCurrency` and `OrderFee.Zero`
- Removing `AccountCurrency` from `Cash` and `Brokerage` classes.
`ICurrencyConverter` will now provide the `AccountCurrency`
- Adding new static `OrderFee.Zero` which will return a 0 order fee in
`NullCurrency`
- Adding static `Currencies.USD` value, replacing all "USD".
- Addin new static `Currencies.NullCurrency`
- Updating Bitfinex `FeeModel` so it return fees in quote currency.
Adding unit tests
- Replacing `decimal` for `OrderFee` at the `OrderEvent`.
- Adding `FeeModelNotUsingAccountCurrency` regression test
- Adding unit tests for `CashBuyingPowerModel` and `SecurityMarginModel`
with non account currency fees
- Adding new `IAlgorithm.AccountCurrency { get; }` that will point to the
`Portfolio.CashBook.AccountCurrency`. Setter will be added in a
following PR.
- Base `Brokerage` class will now have a `AccountCurrency { get }`
pointing to the `IAccountCurrencyProvider`. Will be used by the different
brokerages implementations.
- Refactoring `IFeeModel`. *This is a breaking change* for implementations
inheriting directly from the interface. Deleting old and adding a new method
`OrderFee GetOrderFee(OrderFeeParameters parameters)` that will use a parameter
and a result object.
- Refactoring `CashAmount` so it does not embed a `ICurrencyConverter`
instance.
- Updating unit tests
- The `Security.QuoteCurrency`, a `Cash` instance, will provide access
to the `AccountCurrency` as a property.
- Will maintain backwards compatibility with old python custom
FeeModels, Adding unit test.
> Note that for now, consumers will ignore the currency, as before, and
directly consume the amount
> This PR is a mechanical refactor, no behaviour changed
- Obsoleting `IsFillDataForward`, `Resolution`, `IsExtendedMarketHours`
`Security` configuration properties. Replacing there usages by
requesting the `SubscriptionDataConfigs` to the new
`SubscriptionDataConfigService`
