Regression Tests / build (push) Has been cancelled
Python Virtual Environments / build (push) Has been cancelled
Benchmarks / build (push) Has been cancelled
Build & Test Lean / build (push) Has been cancelled
Research Regression Tests / build (push) Has been cancelled
* Refactor alpha statistics

- Refactor alpha statistics, cleaning up and simplifying no longer required calculations and scoring
- Adding new InsightEvaluator abstraction, adding C# & PY regression
  algorithms

* Optimization backtest result json converter update

* Address reviews

- Remove IAlphaHandler, move insight storage responsability to IResultHandler
  and centralizing insight collection on the QCAlgorithm.Insights to be
  reused by the framework models
- Fix portfolio turnover single day backtests and duplicate time
  sampling handling. Updating regression algorithms

* Add InsightCollection tests and minor fixes

* Adding more & improved tests

Martin Molinero ee4f8fee82 Overall performance improvements
- `TimeSliceFactory` will avoid creating empty collections
- `ExecutionModels` will check target collection count before trying to
enumerate
- Reduce calls to .`TotalPortfolioValue`
- `SecurityValues` will only be created when required
- `TimeKeeper` will use TimeZone unique Id as dictionary key. The
TimeZone hash is expensive.
- `AlgorithmManager` will avoid calling `DateTime.UtcNow`,
`ConvertFromUtc()` and `RoundDownInTimeZone()`

snugs d1a85e0647 Adds TimeKeeper ctor params[] overload 2015-12-07 13:23:39 -05:00
snugs 28d8300e46 Fixes failing tests
Beefs up the UpdateOrderRegressionAlgorithm/updates statistics
Now using TimeKeeper/LocalTimeKeeper for dissemination of time to algo classes
2015-07-09 17:19:40 -04:00
snugs 6bd38ece77 Adds international/timezone support
Time sync:
	* Data feeds are required to time sync in UTC time
	* TimeSlice.Time is now in UTC

IAlgorithm
	* Time is now exclusively the algorithm's local time zone
	* Added UtcTime
	* SetDateTime( DateTime ) accepts a UTC time and is internally converted

SubscriptionDataConfig
	* Adds market and time zone as required ctor parameters

SecurityExchange
	* Now passes most calls directly through to SecurityExchangeHours class

SecurityExchangeHours
	* Holds market hours for each day of week (LocalMarketHours)
	* Talks in terms of local times in the SecurityExchangeHours.TimeZone time zone

Data/market-hours/
	* New data folder to hold market hour information
	* Includes market-hours-database.csv to hold market hours per market/symbol/security (see doc in file)
	* Includes holidays-usa.csv to hold holidays for 'usa' market
		+ The holiday files follow the pattern 'holidays-*.csv' where * is the market

TimeKeeper
	* Receives updates in UTC time
	* Passes that to LocalTimeKeeper's who lazily evaluate the time in their respective time zones
	* Eventually this can grow to be the sole source of time in the algorithm's scope

MISC:
	* Fixes exception thrown when exiting LiveTradingDataFeed
	* Fixes exception thrown when exiting FileSystemDataFeed
	* Fixes exception thrown when exiting StatusPing
	* Simplify FillForwardEnumerator logic with GetNextMarketOpen
	* Adds many time zones, see TimeZones.cs
