Gerardo Salazar 8c6aa6a3b3 Refactors Capacity Estimation and moves estimation to main event loop (#5351)
* Adds CapacityEstimate and SymbolCapacity

  The capacity estimation has been moved from
  the report generator and wired directly into
  Lean via the ResultHandler. In addition,
  the capacity estimation strategy has changed
  to account for errors in the previous iteration
  of the capacity estimation.

  Many many thanks to Jared for being much of the
  mastermind behind this project. It would have
  been harder to complete without him to bounce ideas
  off of.

  * Moves old tests to regression algorithms
  * Adds Estimated Capacity statistic
  * Removes old capacity estimation tests

Final report capacity estimation. Pushing to save state

* Fixes bugs, cleans up code and adds comments

  * Adds forced sampling to Capacity Estimation
  * Misc. bug fixes for daily data

* Updates capacity test cases' Estimated Strategy Capacity statistic

* Adds Capacity Estimate to all regression algorithms

* Removes Report's StrategyCapacity class and fixes bug in tests

  * Adds null check in BacktestingResultHandler to fix
    BacktestingTransactionHandler failing tests

  * Deletes old capacity estimation classes

  * Retrieve capacity estimates from backtest statistics results
    instead of calculating at runtime

* Make $0.00 capacity return as "-" and Result = 0 in report

* Adds capacity to runtime statistics

* Converts capacity to number denoted by financial figures in RuntimeStats

* Addresses review: code cleanup for Capacity and adds comments to regression tests

Gerardo Salazar e2964dd4b1 Make OrderListHash deterministic by using MD5 as its underlying hash function (#5276)
* Update OrderListHash to use MD5 as hash instead of hash code

* Update regression algorithm OrderListHash statistic

* Use full MD5 hash as OrderListHash, update regression statistic

* Fixes failing regression tests

Gerardo Salazar 17ab10531a Fixes ETB/shortable regression algorithms that were previously failing (#5174)
* Fixes ETB/shortable regression algorithms that were previously failing

* Addresses review and fixes bug

  * Fixes bug where orders would be denied regardless of direction
    whenever they exceeded the absolute value of the shortable quantity

  * Updates regression algorithm + statistics + simplifies test

  * Fixes python regression algorithm

* Addresses review: removes comments and unneeded imports

Gerardo Salazar 4d4ad92fa7 Easy To Borrow Hotfix (#5167) 2021-01-14 15:07:54 -08:00
Gerardo Salazar 3e7af17e02 Implements Easy To Borrow Reality Modeling (WIP) (#5159)
* Creates IShortableProvider interface + interface impls

  * This is the foundational work for the addition of the shortable stocks
    feature for backtesting and live trading. Note that the QCAlgorithm
    API and the backend transaction handling will be implemented
    separately.

* temp; work on preorder checks

* improve checks

* tmep

* Enforces ETB checks at BrokerageTransactionHandler

  * Adds ETB Shortable Provider to QCAlgorithm and IAlgorithm
  * Removes ETB check from PreOrderChecksImpl
  * Removes outdated test, new test to come soon for relevant class

* Work in progress commit, pushing for review.

  * Adds new regression algorithm (WIP)
  * Enhances ShortableProviderOrdersRejectedRegressionAlgorithm
  * Adds new methods to QCAlgorithm
  * Move IShortableProvider to have BrokerageModel own it
  * Comments updates
  * Adds new properties to Equity Security for shortable

  * Fixes bug where retrieving open order quantities would aggregate the
    submitted order quantity rather than the remaining order quantity for
    open orders.

  * Fixes bug where quantity of zero would result in a
    false positive in QCAlgorithm.Shortable(...)

  * Code refactoring and comments updates
