* Default daily precise end times
- Enable by default daily precise end times. Updating stats
- Minor fix for algorithm manager consolidator updates, adding new regression test
asserting behavior and updating others
- Minor fix for SubscriptionData creator avoid round down on warmup if
not appropiate
- Adjust consolidators to emit on daily strict end times if requested
daily resolution and setting enabled
- Updating regression algorithms
* Skip daily data on extended market hours
* Some cleanup and self review
* Revert unrequired change
* Changed argument exceptions so that they used the nameof() operator for parameter names
* Update IQSocket.cs

* Improves greeks configurability and defaults for all option asset types
* Makes `StandardDeviationOfReturns` configurable by users, so that
greeks can be loaded according to user expectations and the series
of returns that they'd like to compute for `n` periods and timespan
of `T`, as well as resolution of the data in live mode.
* Changes resolution to max resolution available for the default
volatility model created for the security. Usually this only applies
to live mode, but if creating an instance of the
`StandardDeviationOfReturns` volatility model and no `updateFrequency`
is provided, the resolution's time span will be used as the default
value. Backwards compatibility for equities is maintained.
* Changes defaults for `StandardDeviationOfReturnsVolatilityModel`
to warmup greeks faster for other derivative asset types
* Improves comments on `StandardDeviationOfReturns` for clarity on how
to use the volatility model for end users
* Fixes bug where TradeBar could not have proper Symbol set when getting
max resolution
* Applies to QCAlgorithm.Universe and StandardDeviationOfReturnsVolatilityModel
* Adds tests to check volatility model is updated at specified config intervals
* Address review: add shared method for (Relative)StandardDeviation
volatility models
* Adjusts logic to determine bar type
* Address review: order by TickType when getting configs inside volatility models
- `HistoryRequestFactory` will not sure extended market hours for hour
resolution when determining the start time using quantity of bars.
Adding regression test
* regression tests
* fix: apply the same time convertion to history request time as for data time
* ver2
* fixup

* fix existing tests: submit new btcusd data
* fix
* add Cfd symbol
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`
> This PR is a mechanical refactor, no behaviour changed
- Obsoleting `IsFillDataForward`, `Resolution`, `IsExtendedMarketHours`
`Security` configuration properties. Replacing there usages by
requesting the `SubscriptionDataConfigs` to the new
`SubscriptionDataConfigService`
- Removing usages of Security.Configuration properties from existing
Volatility Models, without modifying existing interfaces. Adding unit
tests for existing behavior
- Adding new BaseVolatilityModel, which will have a setter for a
ISubscriptionDataConfigProvider which will be called by the system.
Adding unit tests for this behavior.
- Adding new `SubscriptionDataConfigExtensions` static class which will
provide methods used to determine different configuration properties for
a given set of `SubscriptionDataConfigs`. The behavior was extracted
from current `Security` class behavior regarding the `SubscriptionBag`.
Adding unit tests covering exepected behavior here.
This method is a convient way to check if the security has a subscription that represents custom data. It returns true if the security contains at least one subscription that represents custom data
Added support for history requirements, exposed by vol models. AM processes requirements.
Added new volatility model - standard deviation of returns - default vol model. Compared its results with publicly available.
Refactored option pricing engine to support optimal approximation calculations.
Added basic greeks approximation in case they are not available in QL. Tests.
Updated BasicTemplateOptionHistoryAlgorithm to print greeks.
