- 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.
- Adding new ISecurityService and its implementation SecurityService.
Expose by SecurityManager.
This class will expose a method for creating new securities. The
SecurityManager is exposing this new interface, calling _securityService
internally, so Future/OptionUniverseSelectionModel.cs can use it
- Replacing all usages of SecurityManager.CreateSecurity for new
ISecurityService
- Modifying `Cash.cs` and `CashBook.cs` `EnsureCurrencyDataFeeds()` to
return newly added `SubscriptionDataConfig` instead of `Security`. This
will avoid using `Security.Subscriptions` at call site.
- Moving old SecurityManager.CreateSecurity into new
SecurityServiceTests.cs
The ConfigureOptionChainSecurity method somewhat was overshadowing the security
initializer's responsibilities. This method has been trimmed down into a contract
filter function sub classes can use to define what option contracts they want to
select.
This change allows the universe selection model to select different universe
definitions as time proceeds. This enables the definition of a universe model
that, for example, could add option chains for securities selected by a different
universe model.
The BasicTemplateOptionsFrameworkAlgorithm was added to showcase and provide
regression for a universe model that selects different universes.
