The `NullReferenceException` type is intended to only be thrown by the CLR.
In most cases, it should be converted to an `ArgumentException` or an
`InvalidOperationException`, depending on if the null value is a parameter
to the current method or not.
The `Exception` type should never really be thrown as it doesn't provide any
additional information or hints as to the issue. It also forces users that
would like to handle expected exceptions to catch all exceptions. These are
converted to an exception type that more accurately describes the reason for
raising the exception: `KeyNotFoundException`, `InvalidOperationException`
- `SecurityTransactionManager.TransactionRecord` will now be thread safe.
`SecurityTransactionManager` will internally wrap usage of `TransactionRecord` with
a lock.
This method is being added to allow algorithms to complete initialization tasks that cannot be executed during Initialize, such as cancelling existing open orders in live trading.
This method will be called only once, when the warmup task is complete.
Closes#1043
1. Made sure we treat properly option expiration dates before Feb 2015 and after. Added tests.
2. Refactored expiration delisting, assignments/option exercise to happen in the end of the date, not MOC orders in the beginning of the day. Regression test.
3. Refactored option exercise model to generate proper fills on assignments/option. Those fills are reflected correctly in margins, in stats and correspond to IB model. Still need to run IB real-life live tests.
4. Refactored option symbol related functions into separate module (OptionSymbol.cs)
5. Made sure OnAssignmentEvent arrived to the user algo in regression test. Do we need OnExercise event? Not sure.
6. Tested end-to-end Ray's current code (covered call strat) to see short option legs expire worthless, and stats updated.
QCAlgorithm order functions now return an OrderTicket
OrderTicket can be used to directly update or cancel an order
Placing an order now submits an OrderRequest which is processed by the ITransactionHandler
Changed system to use Margin Models, removing leverage wherever possible allowing for dynamic margin models.
Created first portfolio fill model for FOREX which treats it as a currency swap through the cashbook instead of a tradable asset.
Updated the Securities/SecurityPortfolioManager to use cashbook value + holdings removing FOREX virtual positions.
Created a new benchmark system for comparing quantconnect builds.
