IAlgorithm DebugMessage, ErrorMessage and LogMessage are now ConcurrentQueue<string> instead of List<string> because List.Add is not thread safe.
Copying a list (using ToList()) at LiveTradingResultHandler while adding an element to it at QCAlgorithm caused a runtime error.
The default value for the market parameter in AddForex, AddOption, AddEquity and AddCfd is null. This allows unspecified markets to be set from the BrokerageModel.DefaultMarkets in the AddSecurity method for new securities added with these methods. SetBrokerageModel updates BrokerageModel.DefaultMarkets and therefore the market used for all new securities.
Implements IPriceVariationModel interface which takes the security object and returns a decimal variation
Implemets SecurityVariationModel class: default implementation of IPriceVariationModel that returns a fixed value (read from symbol-properties-database) for decimal variation
Implemets EquityVariationModel class: implementaion of IPriceVariationModel that returns a decimal variation as a function of equity price
Implemets AdjustedPriceVariationModel class: implementaion of IPriceVariationModel that returns zero

Adds WindowIdentity indicator and its test. We need this at WeightedBy to keep values and weights at sync (same sample number).
Adds WeightedBy indicator extension and a simple test in IndicatorExtensionsTests
Adds VolumeWeightedAveragePriceIndicator (VWAP indicator), its test and external data file for testing.
When this was originally written, we were assuming one subscription per security.
This removes that assumption and tries to find subscriptions matching the request
Subscriptions can now be explicit as to whether or not a SubscriptionFilterEnumerator is to be applied.
Regular security price data subscriptions get filtered (user/market-hours)
Universe subscriptions don't get filtered (even if a subscription of equity price data, such as options underlying feeds)
