- `SecurityIdentifier` will calculate `StrikePrice` just once. Replacing
`!=` for a direct call to `Equals()` preventing unnecessary checks.
- Slightly improving Linq queries at `OptionFilterUniverse`
- Replace `OpenReader().CopyTo` for `Extract(stream)` avoids copying the
data twice.
- Replace `DateTime.Now` for `DateTime.UtcNow`
- Adding new regression test algorithm
- `SecurityPortfolioManager` will subscribe to the `CashBook.Updated`
event to invalidate the `TotalPortfolioValue
- Adding new `Updated` event for `Cash` and `CashBook`. Adding unit
tests.
- `CashBook.Update` event will also be called for updates in the `Cash`
instances he holds.
- `Futures` and `CFDs` sales value will use `ContractMultiplier` as the
rest of the securities.
- `FitnessScore` values will be truncated, not rounded, to 3 decimal places.
- Reducing code duplication for calculating the
`CompoundingAnnualPerformance`
- Adding `LazyToUpper()` implementation, that will avoid the call to
`ToUpper` if the string is already upper.
- Reduce the timezone conversions at `Time.EachTradeableDayInTimeZone`
- `TotalPortfolioValue` will iterate over all securities once
- Adding new `SecurityIdentifier` cache, significant impact for
algorithms using coarse/fine data
- `TimeSliceFactory` will avoid creating empty collections
- `ExecutionModels` will check target collection count before trying to
enumerate
- Reduce calls to .`TotalPortfolioValue`
- `SecurityValues` will only be created when required
- `TimeKeeper` will use TimeZone unique Id as dictionary key. The
TimeZone hash is expensive.
- `AlgorithmManager` will avoid calling `DateTime.UtcNow`,
`ConvertFromUtc()` and `RoundDownInTimeZone()`
Energy futures (CL, HO, RB, NG) expire in the month before the contract month.
To handle these properly, the following changes have been implemented:
- the AlgoSeekFuturesReader has been updated to create the future symbol with the correct expiry date
- the zip entry names in futures data files now contain the full expiry date (in addition to the contract month)
- the sample data files have been updated to use the new zip entry names
- new unit tests have been added and existing ones updated
Remove usage of DateTime.UtcNow in buying power models
In PR#3013 we added support for fee models with history, so the new changes to the GDAXFeeModel exposed this bug, breaking a couple of regression tests (issue #3044)
Update regression stats for EmitInsightCryptoCashAccountType
* Fix typos
Add missing time keeper in CashBuyingPowerModelTests
AJY, AKL, AKZ, ANE, APS, AR0, ARE, AUP, AVZ, AW, AYV, AYX, AZ1, B0, B7H, BCF, BIO, BK, BOO, BR7
Correct wrong entry for symbol ZT in symbol-properties-database
Add missing holidays or early closes for energies and fx in mhdb
- `FactorFile` will keep an ordered reversed list with the dates.
Calling `Reverse()` on the `SortedList` is expensive.
- `MapFiles` will keep first and last date, so we don't need to call
`First()` and `Last()` multiple times.
- `Liquidate` will go through all the algorithms securities only if
necessary
- `TradeBar` parsing will not call `new T` for pure `TradeBar` which is
expensive
- Removing `Lazy` hash code and security type for the
`SecurityIdentifier`, replacing for direct initialization. Accessing the
`Lazy` value adds an overhead.
- Replacing `Enum` to string for hardcoded switch statement. `Enum.ToString` is expensive.
- `DataManager` will be lazy for counting the subscriptions for
determining if its above the limit
- Adding `AlgorithmSecurityValuesProvider.GetAllValues()`, removes the
need to fetch all the security keys twice.
- During universe selection, will not try to re add already added symbol
Implements `DataNormalizationMode` field in `UniverseSettings` to enable the settings of a desired `DataNormalizationMode` to the securities that are chosen in Universe Selection.
- Using `Aggregate(lambda)` vs `Sum(lambda)` since the later is slower
due to performing an extra `Select`
- For `QCAlgorithm.Framework.OnFrameworkData()` will avoid calling
`ToArray()` on empty `Enumerables` due to its cost * the number of
calls. If the `Enumerable` is the empty instance, which is static,
will create a new empty array and return it instead.
- Replacing `SecurityIdentifier` `SecurityType` and `GetHashCode`
implementations for `Lazy` versions, that are performed just once, since
these values do not change and are used multiple times.
- For the different `DataDictionary<T>` implementations adding `this[
Symbol] get; set` since existing overload `this [string]` produces an
extra round operations `Symbol->string->Symbol` with a significant
impact.
- Adding `PortfolioTargetCollection.AddRange()` overload using an array
to avoid unnecessary convertions.
- 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.
Adds Russell 2000 E-Mini (RTY), Nikkei 225 Dollar (NKD) and Sugar 11 CME Globex (YO) to future data: entails update entries in market hours and symbol properties databases.
Updates `FutureExpiryFunction` to handle these contracts expiration date.
- Adding new `SetAccountCurrency()` for backtesting. Has to be called
before adding any `Security` or calling `SetCash()`, else will throw.
- Adding new Non account currency unit tests for `CashBuyingPower`,
`SecurityPortfolioModel`, `SecurityMarginModel`,
`SecurityPortfolioManager`, `Future/OptionMarginBuyingPowerModels`
- Adding new C# regression test using `SetAccountCurrency()`, one for
`CashBuyingPowerModel` and one for `SecurityMarginModel`
- Adding new Py and C# basic regression algorithms using
`SetAccountCurrency()`
- `Options` and `Futures` will use not use `AccountCurrency` as quote
Cash.
- `SecurityBenchmark` value will be in account currency
- Removing OrderFeeParameters.AccountCurrency. Where required replacing
for constructor parameter defaulting to USD.
- Updating IB fee model to use to correct fee currency
