    • 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.

    • Include Order.Tag/OrderEvent.Message in their ToString, Fix default tag values

    There was inconsistencies in what we were checking for. The order constructors
    default the tag parameter to an empty string but Order.CreateOrder checks for
    a null string. Additionally, the order constructors (limit,stopmarket,stoplimit)
    would check for an empty string and if so, apply a default order tag.

    This change cleans these checks up using string.IsNullOrEmpty and also removes the
    check from Order.CreateOrder since we're passing the tag into the various order
    constructors.
