Michael Handschuh cf9b547e2e Refactor OptionExerciseOrder.Quantity to be consistent with other Order types (#4796)
* Improve information tracked in regression's {algorithm}.{lang}.details.log

The details.log file aims at providing a diff-able document that quickly and
easily provides actionable information. Since many regression algorithms use
the algorithm's debug/error messaging facilities to log various pieces of algo
state. This document also support a configuration option: regression-high-fidelity-logging'
that logs EVERY piece of data, again, with the aim of providing an easily diff-able
documenbt to quickly highlight actionable information. I may have missed omse key
pieces of information here, but now that the entire QC knows about this regression
tool, if additional information is required then hopefully it's easy enough at this
point to extend the RegressionResultHandler to suit our needs.

The RegressionResultHandler was initially implemented to provide a concise log of
all orders. This was achieved by simply using the Order.ToString method. While
testing/investigating OptionExerciseOrder behavior, it became evident that more
information was required to properly identify the source of potential failures or
differences between previous regression test runs. This change adds logging for
almost every IResultHandler method and additionally attempts to capture the
actual portfolio impact of every OrderEvent. This is accomplished by logging
the portfolio's TotalPortfolioValue, Cash properties and the security's
SecurityHolding.Quantity property.

This change also standardizes the timestamps used to folloow the ISO-8601 format.

When using the RegressionResultHandler, it is highly recommeded to also disable
'forward-console-message' configuration option to ensure algorithm Debug/Error
message logging is done synchronously to ensure correct ordering with respect to
log messages via Log.Debug/Trace/Error.

* Fix typo in options OrderTests test case name

* Update SymbolRepresentation.GenerationOptionTickerOSI to extension method

Far more convenient as an extension method

* Improve R# default code formatting rules

Many of these rule changes focus on improving the readability of code,
with a particular emphasis on multi-line constructs, chained method calls
and multi-line method invocations/declarations.

* Add braces, use string interpolation and limit long lines

* Refactor OptionExerciseOrder.Quantity to indicate change in #contracts

For all other order types, the Order.Quantity indicates the change in the algorithm's
holdings upon order execution for the order's symbol. For OptionExerciseOrder, this
convention was broken. It appears as though only exercise was initially implemented,
in which case only long positions were supported and a code comment indicated that
only positive values of quantity were acceptable, indicating the number of contracts
to exercise. At a later date, assignment simulation was added and utilized a negative
order quantity. This caused some major inconsistencies in how models view exercise
orders compared to all other order types. This change brings OptionExerciseOrder.Quantity
into alignment with the other order types by making it represent the change in holdings
quantity upon order execution.

This change was originally going to be much larger, but in order to minimize risks and to
make for an easier review experience, the additional changes will be committed separately
and pushed in their own PR. Some of the issues identified include:
* Manual Exercise (especially for OTM) is not covered
* Margin Calculations (in particular taking into account opposing contracts held)
* IBrokerage.OptionPositionAssigned is raised for exercise (later filtered by tx handler)

Fixes OptionPortfolioModelTests to use exercise model to properly model exercise of
non-account quote currency option contract.

Michael Handschuh c7a74306fb Bug 4731 Fix Option Expiration Order Tags and Order Event IsAssignment Flag (#4743)
* Add OrderRight.GetExerciseDirection(isShort) extension

Returns the OrderDirection resulting from exercise/assignment of a particular
option right

See: BUG #4731

* Fix option exercise/assignment order tags and order event messages

The algorithm manager was doing work to determine whether or not the option ended
in exercise or assignment at expiration. This decision should be left for the exercise
model to decide -- from the algorithm manager's perspective, all that matters is that
the option was expired. The DefaultExerciseModel was updated to properly track whether
the option expired with automatic assignment or exercise, dependending on whether or
not we wrote or bought the option (held liability or right, respectively). Updated unit
tests to check for order event counts and order event messages for option exercise cases.

Fixes: #4731

* Fix typo in algorithm documentation

* Update regression tests order hash
