* Since IB eats into our account's cash balance when
a new FOP contract is purchased, we must model by applying funds
to our cash whenever a new purchase/sell occurs.
If we choose to model FOPs exactly as we do with futures, we
will end up with an invalid TotalPortfolioValue on algorithm
restart. By all means and purposes, FOPs are modeled exactly
the same as equity options with respect to the portfolio.

expiry lookup in the futures expiries returned from CME
* Fixes multiple looping bug in LiveOptionChainProvider
* Adds strike price scaling for LiveOptionChainProvider
* Reverts IQFeed changes and simplifies interface upgrade changes
Some additional challenges we'll have to solve as part of FOPs:
- The `OptionSymbol.IsStandard` method makes the assumption that
weeklies contracts follow the pattern equities follows, which
does not apply to Futures Options
- The Subscription created in:
`OptionChainUniverseSubscriptionEnumeratorFactory`
...adds a Trade config. For illiquid contracts, this
will delay universe selection for the option symbol
until we get a trade. However, if we add a quote config,
the data would instead be loaded based on the first quote
we received from the brokerage.
But since we're currently using a trade config, illiquid
contracts won't start streaming data until it receives a trade.

* Reformat/cleanup OptionStrategies
This file was breaking pretty much every style convention in LEAN.
There are other things that should be addressed in here that weren't,
such as passing non-argument names as argument names for ArgumentException,
as well as preferring constructors over property initializer syntax, but
such changes aren't being made to keep this commit strictly reformatting
instead of refactoring.
Added braces and reformatted long lines to make code more legible.
* Add abstract base class for OptionStrategy Option/UnderlyingLegData
This allows us to create either or and later use the Invoke method to push it
into the appropriate list on OptionStrategy.
* Replace O(n) option contract search with 2 O(1) TryGetValue calls
A better improvement would be resolving the correct symbol in the strategy, but
this immediate change is instead just focused on removing the O(n) search inside
a loop.
* Add BinaryComparison and supporting methods in ExpressionBuilder
We're going to use these binary comparisons to make it possible to create
ad-hoc queries against a collection of symbols. Using these expressions,
along with type supporting composition of these expression, we'll be able
to define predicates that can declaratively define how to match an option
strategy with an algorithms current holdings.
* Make GetValueOrDefault defaultValue optional
Was receiving ambiguous invocations leading to neading to invoke this
method explicitly (LinqExtensions.GetValueOrDefault) instead of being
able to use it as an extension method. Making the default value optional
seems to have resolved this ambiguity, leading to cleaner code in the
OptionPositionCollection (forthcoming)
* Add OptionPosition and OptionPositionCollection
OptionPositionCollection aims to provide a single coherent interface
for querying an algorithm's option contract positions and the underlying
equity's position in a performant, immutable way. The immutability of
the type is necessary for how the options matcher will operate. We need
to recursively evaluate potential matches, each step down the stack removing
positions from the collection consumed by each leg matched. This will enable
parallelism of the solution as well as simplifying the mental model for
understanding due to not needing to track mutations to the collection
instance.
* Add Option test class for easily creating option symbol objects
* Add OptionStrategyLegPredicate and OptionStrategyLegDefinition
The definition is a composition of predicates, and each predicate supports
matching against a set of pre-existing legs and a current position being
checked for the next leg (this leg). In addition to the matching functionality,
it also supports filtering the OptionPositionCollection, which is where much
of the work for resolving potential option strategies is done. By successively
filtering the OptionPositionCollection through successive application of predicates,
we wil end up with a small set of remaining positions that can be individually
evaluated for best margin impacts.
All of this effectively unrolls into a giant evaluation tree. Because of this
inherent structure, common in combinatorial optimization, the OptionPositionCollection
is an immutable type to support concurrent evaluations of different branches of
the tree. For large position collections this will dramatically improve strategy
resolution times. Finally, the interface between the predicate and the positions
collection is purposefully thin and provides a target for future optimizations.
* Add OptionStrategyDefinition and OptionStrategyDefinitions pre-defined definitions
The OptionStrategyDefinition is a definitional object provided a template and functions
used to match algorithm holdings (via OptionPositionCollection) to this definition. The
definition defines a particular way in which option positions can be combined in order to
achieve a more favorable margin requirement, thereby allowing the algorithm to hold more
positions than otherwise possible. This ties into the existing OptionStrategy classes and
the end result of the matching process will be OptionStrategy instances definiing all
strategies matched according to the provided definitions.
* Add OptionStrategyMatcher and Options class, w/ supporting types
OptionStrategyMatcherOptions aims to provide some knobs and dials to control how
the matcher behaves, and more importantly, which positions get prioritized when
matching. Prioritization is controlled via two different enumerators, one controller
which definitions are matched first and the other controller which positions are
matched first. Still unimplemented, is computing multiple solutions and running the
provided objective function to determine the best match. When this gets implemented,
we'll also want to implement the timer. For anyone looking to implement these features,
please talk with Michael Handschuh as there's a particular way of representing these
types of combinatorial solutions (a 3D tree) that can be used as a variation of the
linear simplex method for optimizing combinatorial problems.
* OptionStrategyMatcher: Address PR review comments
* Ensure created OptionStrategy legs all have the same multiplier
Each leg definition match gets it's own multiplier which indicates the
maximum number of times we matched that particular leg. When we finish
matching all legs, we pick the smallest multiplier from all the legs in
the definition and use that as the definition's multiplier. When we go
to create the OptionStrategy object we MUST make sure we're using the
multiplier from the definition and not from the individual legs.
This change fixes this issue and also provides a guard clause to ensure
that we're not trying to use a multiplier larger than what was matched.
* Add XML docs for OptionStrategyDefinitions from OptionStrategies
* Fixes 4815 by loading the requested assembly from different folder.
# Conflicts:
# ToolBox/Program.cs
* Upgrades System.Collections.Immutable to Version=1.2.5.0
* Creates a prototype for SSE streaming in IEXDataQueueHandler.
* Revert the changes in Tick.cs
* Implements a logic in IEXDataQueueHandler that updates the data-feed subscription after Subscribe/Unsubscribe
* Implements IEXCouldSubscribeMoreThan100Symbols - which fails and other small fixes.
* Implements DoForEach LinqExtensions
* Implements IEXEventSourceCollection that wraps all logic that is SSE-subscriptions and symbol-limits-per-connection concerned.
* Changes:
1) Fixes to address review.
2) Makes IexMarketPercent in QuoteSSE nullable as null values are assigned to in this field in data object received before the traing session start.
3) Deprecates helper Subscribe/Unsubscribe in IEXDataQueueHandler and IEXCouldSubscribe test.
* Fixes:
1) _refreshEvent.Reset() order was not correct - should be called before UpdateSubscription
2) ProcessJsonObject- leaves only the functionality to emit ticks.
3) IEXEventSourceCollection - replaces int counter with CountdownEvent to improve the logic - in particular, need a mechanism that would not allow the repeated call to continue until the first one is completed
* Refines the logic with parsing a data snapshot.
* Fixes few more bugs:
1) Logic in ProcessJsonObject
2) Logic in UpdateSubscription - need to introduce additional ManualResetEvent to implement the intended logic - otherwise the logic is not suitable for general case
* Introduce rate-gate limit in IEXEventSourceCollection:
because when subscribing to a bunch of shares (more than 200 for example)
the violation of rate gate policy may occur, which described in API docs asRequest Limits
IEX Cloud only applies request limits per IP address to ensure system stability.
We limit requests to 100 per second per IP measured in milliseconds, so no more than 1 request per 10 milliseconds.
SSE endpoints are limited to 50 symbols per connection. You can make multiple connections if you need to consume more than 50 symbols.:
* Few additional fixes done after real time testing
* Adds xml-docs in stream response object + renaming a file.
* Fixes:
1) Additional StreamResponseStocksUS parsing issues, that can happen outside of regular exchange hours.
2) Cancel clientUpdateThread by means of CancellationTokenSource
3) Replace BuildSymbolsQuery by string.Join
* Fixes:
1) Changing Log Trace -> Debug
2) Adds ConfigureAwait(false) to async method call
3) Removes direct reference to System.Net.Http
* Removes a task and manual reset event in IEXEventSourceCollection
* Additions:
1) IEXEventSourceCollectionSubscribes test
2) GetSnpStocksArray() helper method
3) Installs packages in QC.tests : HtmlAgilityPack & LaunchDarkly.EventSource
* IEX history provider fixes :
1) Tiny bug in ProcessJsonObject - use continue instead of return as execution is inside the for-each block)
2) Adds period variable for the historical data retrieved
3) Fixing from if (date.Date < start.Date || date.Date > end.Date) conditional check --> if (date < start || date > end) for more precise sorting.
* Changes:
1) Removes HtmlAgilityPack and SNP scraper
2) Uses hard coded symbols instead
* Bug fix:
- at certain hours (example: before pre-market open or on holidays) IEX may send no data on subscription - when trying to connect during those hours Message handler may not be fired - need to place the counter signal to client.Opened to be informed of successful connect.
* Implements:
1) IEXEventSourceCollectionSubscriptionThoroughTest and MockedIEXEventSourceCollection
2) Makes changes to IEXEventSourceCollection accordingly to allow the thorough testing.
* Fixes formatting issue in StreamResponseStocksUS
* Small fix for a new tests:
- Change RemovedClientSymbols to keep not clients itself, but symbols array, because clients are being disposed right further
* Enables extended logging in Toolbox.
* Fixing IEX historical data fetcher bugs:
1) Bug in IEXDataDownloader.cs - HistoryRequest not precisely correct.
2) Enables day-by-day daily bar downloading in IEXDataQueueHandler.
Motivation: Suppose we need data for some interval in the past - from-date=20170915-00:00:00 --to-date=20171103-00:00:00.
With current behavior IEX would have to download all the historical data from =20170915-00:00:00 up to this day.
3) Extends SynchronizingHistoryProvider
* Enables async fashion historical data download
* More fixes to IEXCouldGetHistory test.
* Reverts day-by-day daily bar downloading and other fixes.
* Removes needless packages & references
* Fix package reference
* To address review
* Sort out zero price ticks:
after testing on real-time algo 30 min before the market open now - IEX may send updates for many securities with zero lastPrice, lastSize - fix to sort such entries out
* Workaround for missing QuoteTicks timestamps:
Since we don't have a stamp for quote tick updates (only for trades) we calculate the average delay between trade tick's time stamp and local time, and
assuming that delay in average is the same for quote updates - just assign the local machine time adjusted for this average
* Simplifies the things.
* Changes:
1) Deprecates quote updates for IEX stocks.
2) Reduce the stream updates to reduce costs to ->
# Stock Quotes every 1 second (per symbol? )
# Can be up to 54,000 messages per symbol per day
https://iexcloud.io/docs/api/#how-messages-work
* Fixes:
1) IEXDataQueueHandler: give an error message on extended market hours or tick resolution subscription request. As they are not really well supported by IEX.
2) Few small fixes in IEXEventSourceCollection, including additional condition for when the subscription remains irrevocable.
- Reduce ResultHandler amount of packets sent and their size.
- Only send order and orderEvents packet if there is actually data in them.
- Don't send Holdings fields if value is 0
- Don't send AlphaRuntimeStatistics fields if default values
- `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.
This follows the pattern used by delisting events, where we send a warning event
before the start of trading on the trading day before the split will happen. This
change also adds a SplitType enum having a Warning and SplitOccurred values.
* Recommitted. Fixed missing code
* Renamed tests for Api to ApiTests
* Renamed Live to LiveAlgorithm
* Add LiveAlgorithm configuration classes for supported brokerages
The QuantConnect api v2 enables users to launch live algorithms with one of the supported brokerages. The LiveAlgorithmSettings class adds brokerage specific configuration classes that will allow algorithms to be configured to run live on a specific brokerage.
* Projects can now be updated via the Api v2
* Projects can be created via the Api with LiveAlgorithmSettings class
* Renamed CreateLive to CreateLiveAlgorithm in IApi
* Added tests for luanching live algorithms via api V2 for brokerages
* Created ProjectUpdateResponse to represent api response when project is updated
The new class ProjectUpdateResponse derives from RestReponse and adds a field, Files, that represents the project files associated with a project. This new class is now what the Api method returns. A new test, Update_ProjectFiles_Successfully, tests updating the files for a project via the Api
* Refactored ApiTests and expanded ApiTest docs
* Renamed brokerage specific classes that derive from BaseLiveAlgorithmSettings
* Refactored Oanda and Tradier LiveAlgorithm settings
Tradier and Oanda do not required certain parameters like password and username to trade live, however, they are required for the QC Api v2. A new constructor was added to BaseLiveAlgorithmSettings that does not take in these parameters and sets the unneeded parameters to blank strings. Tradier and Oanda LiveAlgorithmSettings implement this new constructor.
* Minor tweaks to OandaLiveAlgorithmSettings
* Brokerage Api tests now use appropriate algorithms
Some brokerage tests were using algorithms that traded securities that did not pertain to the brokerage. This has been corrected.

* Removed BrokerageName from LiveAlgorithmSettings.
* Fixed spelling mistake
* Added custom JsonConverter for LiveAlgorithmResults
In order to properly deserialize the results of an algorithm from the api endpoint "live/read", a custom deserializer is added to deal with null ChartPoints. In order to deserialize ChartPoints that are null, ChartPoint has been changed from a struct to a class.
* Fixed type-o in ApiTests
* Add Ignore NUnit attribute to ApiTests
* Removed ApiAlgorithmStatus
In order to better align with the rest of the project, ApiAlgorithmStatus has been replaced by the existing AlgorithmStatus enum. Only certain values of AlgorithmStatus can be used with the Api. Unsuported values throw an ArgumentException error.
