- Removing OrderFeeParameters.AccountCurrency. Where required replacing
for constructor parameter defaulting to USD.
- Updating IB fee model to use to correct fee currency
- 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
- 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 an attempt to reduce contention in concurrent dictionaries, replacing method calls using full locks with lock-free equivalents:
- dictionary.Count -> dictionary.Skip(0).Count()
- dictionary.Keys -> dictionary.Select(x => x.Key)
- dictionary.Values -> dictionary.Select(x => x.Value)
The most frequent usages of these methods are: CashBook, SecurityManager, UniverseManager and indirectly, SecurityPortfolioManager.
The reasons for this update are explained very clearly in this article:
