Make PrimaryExchange as default even if the IPrimaryExchangeProvider is not instantiated
* Revert breaking change.
* Add a check that resolved map file actually have content
The issue that leads to this change was caused by a map file resolved to APC in the CoarseFundamentalTop3Algorithm.
The resolver returns a not-null MapFile, but it is empty.
To my best understand, the MapFile Resolver should return only existing map files in the map_files folder. But the LocalMapFileProvider returned a map file with a permtick that doesn't exist in the file system as CSV.
* Set PrimaryExchange.UNKNOWN as default
* Address review couple minor bugs
- Use SID market instead of USA
- Default ticke exchange is UNKNOWN
* Update map files with latest format and latest info
This include:

This commit is squashed from iterative development:
- More consistent method naming
- Storage root path updated to be absolute and include algorithm name
- Storage root path created only if object store is actually used
- Implemented XML save/load
- Added missing unit tests
- Replaced Log.Trace with Log.Error calls
- Added the object store name logging in Engine.Main
- Read storage root from config
- Create algorithm storage root folder in Initialize
- Remove empty folder in Dispose
- Added null checks in all methods
- Added missing XML parameter docs
- make Initialize and Dispose virtual
- make AlgorithmStorageRoot protected
The IObjectStore abstraction provides algorithms with a persistent
storage mechanism. While the algorithm is running, data is maintained
in memory as a dictionary of raw bytes (string -> byte[]). This ensures
we avoid any reference type shenanigans. Periodically, the data in the
object store is persisted and additionally, when the algorithm shuts
down, the object store's data will again be persisted. This ensures that
when the algorithm starts up again, it will have access to any state
that has been saved into the object store.
A great use case for IObjectStore is saving a compute heavy model.
For example, computing the weights of a deep neural network is very
CPU intensive, but after the weights are computed, evaluation is fairly
quick. An initial backtest can be used to solved for the network's weights
and then subsequent backtests or even in live mode, the weights will be
available to the algorithm provided they were saved into the object store.
Also, some libraries require a file path to load model data. The object
store provides a `GetFilePath(key)` method which will copy the data for
the provided key to the disk and return that path so the library can load
the model data.
- `SubscriptionDataReader` will check map file first data and adjust
start date based on it
- Adding unit test
- Reducing code duplication
- Setting up `HistoryProvider` event handling
- Adding `SecurityCacheProvider` this class allows for two different
`Security` to share the same data type cache through different instance
of `SecurityCache`. This is used to directly access custom data types
through their underlying in a peformant maner
- Some small improvements
In order to continue to provide debugging support in the QC cloud, the
scheduled events were moved from inside of a task to the algorithm's
main execution thread. This necesitated a different methodology for
managing timeouts. Instead of raising an exception when attempting to
request additional time when none is remaining, we're now simply allowing
the isolator's limit to be reached by virtue of not incrementing the
additional minutes in the time manager. This uncovered a bug in LEAN
engine where if the isolator terminates an algorithm, then the status
of the algorithm (on the algorithm manager instance) isn't properly
updated to indicate RuntimeError. This is in direct conflict with the
status update that is provided to the api, which is RuntimeError, so
this change remedies that issue as well. One of the regression algorithms
depends on this status value being properly flipped to RuntimeError in
the event that the isolator limit is reached.
See #3319
We restrict each algorithm time loop to a pre-determined amount of time.
Exceeding this limit will cause the algorithm to immediately terminate.
This quickly becomes an issue when considering users running trainable
models that have a long initialization period that exceeds the time loop
maximum.
This change provides a mechanism through which a long-running scheduled
event is permitted to keep running and is permitted to avoid the time loop
permitted by requesting additional time. Requests for additional time are
limited according to a leaky bucket implementation whose parameters are
set via the job's controls structure. The fundamental time unit for the
algorithm is a single minute.
Here's how it works. If a scheduled event takes longer than one full wall
clock second then a request is made to the leaky bucket for one more minute.
If the scheduled event continues to take more time, it will continue to
request additional minutes. Each requested minute will prevent the algorithm's
time loop check from terminating the algorithm. When the bucket is empty and
no more minutes are available to be requested, a TimeoutException is thrown
causing a cascade that ends in the algorithm's termination and status being
flipped to RuntimeError.
Additionally, this applies equally to ALL scheduled events. While some helpers
were added with the naming of Train and TrainNow to the ScheduleManager, these
methods don't do anything special and the infrastructure doesn't otherwise
flag them as different, so this feature becomes part of the core Scheduled
Event feature set.
Further, the live scheduled events were not touched and are still pending
further discussion regarding the value added by enforcing a time restriction
when simulation time and wall clock time are equivalent.
Fixes#3319
Extracting this behavior into it's own class. We'll later extend
the functionality of the implementation to enable a training event
a mechanism for extending the current time loop maximum and/or for
flat out disabling it while the training is runnig and the leaky
bucket has capacity.
Adds IRegisteredSecurityDataTypesProvider to track all the data types
registered in the algorithm. Using this data, we can detect if it's
possible that we'll eventually have a property of a certain type name.
For example, consider I wish to use security.Data.TradeBar but we haven't
received any trade bars yet. Before this change a KeyNotFoundException
would be raised, but since we can determine that we expect to have trade
bars, we can detect this and return an empty list when we haven't received
any data yet. This also removes the need to constantly do a HasData<T>()
check before accessing the dynamic members.
Closes#3620
- For backtesting the algorithm thread will sequentially process pending
order requests
- Adding new non blocking `BusyCollection`
- Updating `UpdateOrderRegressionAlgorithm` that suffered of a race
condition: it supposed `OnOrderEvent` would be called after the call to
`Transactions.AddOrder()` was finished
