* Add documentation for cfd, crypto, forex, future, and option data
* Update data documentation to ensure consistency
* Fix titles, removed timezone reference
Adds reference price to dividend/split
Adds GetSplitsAndDividends to FactorFile
Adds Apply methods to FactorFile/FactorFileRow
Updates factor files to include reference prices
- The algorithm has been renamed to CoarseFundamentalTop3Algorithm and updated to select the Top 3 instead of Top 5.
- The only new data required is daily, map and factor file for FB and has been added (map and factor files are dated 6/4/2018, as required by all regression tests).
- The coarse fundamental open source data has been updated.
- The expected regression statistics for the algorithm have been updated.
It's important that we keep the factor files consistent with respect to
the date that they were generated. This enables us to run the regression
algorithms in the cloud and get the same results by using the factor files
from the correct date.
Prevents logging the following error:
ERROR:: DefaultDataProvider.Fetch(): The specified file was not found: ../../../Data/equity\usa\minute\spy\20131004_trade.zip
DataFeeds now expose a single bridge (BlockingCollection<TimeSlice>)
- IDataFeed now responsible for all time syncing, DataStream was removed
- BlockingCollection allows for easy throttling of data feed thread without sleeps (internally using semaphore slim)
- Slimmed down IDataFeed interface to not include members unused externally
DataFeeds now use raw IEnumerator<BaseData> instead of subscription data readers directly
- Simplifies fill forward logic (see FillForwardEnumerator.cs and FillForwardEnumeratorTest.cs)
- Allows for composition (raw reader -> fill forward, user/market filters)
- SubscriptionDataReader now handles refreshing source (continuous enumeration)
LiveTradingDataFeed cleaned up to work with time slice bridge
- RealTimeSynchronizedTimer handles pushing time slices into bridge every second, with or without data
- Subscriptions with tick resolution get their data pushed directly into the bridge immediately
Fill forward changes
- Implemented as an IEnumerator<BaseData>
- Fill forward lower res on higher res (daily gets filled forward on second/minute/hour bars)
- Second/minute/hour will not be filled forward on daily bars (at midnight) in line with current behavior
MISC:
- Performance boost in backtesting brokerage via not checking _pending.Count, instead use local bool to determine if there's pending orders
- Added a FakeDataQueue to aid in testing LiveTradingDataFeed
- FileSystemDataFeed now uses CancellationTokenSource to handle thread exits
- Added logging
