Summary

  • Fix live Bitunix history by using supported native intervals and paginating bounded timestamp windows at the exchange limit of 200 candles.
  • Fix live Coinbase and other CCXT history pagination by advancing since to last candle + timeframe, then fail clearly when provider history is genuinely short.
  • Fix base broker and backtesting crypto-futures closes by constructing side-correct reduce-only orders, filtering null bulk closes, and guarding null submissions.
  • Preserve the existing 4.5.91 release-gate evidence reuse change already present on the shared version branch.

Customer feedback context

TDD evidence

Red phase before production changes:

Repro Before
Bitunix live 15m request 14 / 20 bars
Bitunix live 1h request 4 / 10 bars
CCXT inclusive-cursor pagination 1 / 3 bars
Crypto-futures backtest close AttributeError: NoneType has no attribute order_class

Green phase after fixes:

Repro After
Bitunix live 15m native request 20 / 20 bars
Bitunix live 1h native request 10 / 10 bars
Bitunix paginated 1m request 450 / 450 bars across 3+ pages
CCXT inclusive-cursor pagination 3 / 3 bars with 60,000 ms cursor advances
Crypto-futures backtest close reduce-only Order; filled close removes tracked position

Validation

  • pytest -q tests/test_live_crypto_history_pagination.py tests/test_crypto_future_close_position.py: 9 passed.
  • Adjacent Bitunix, CCXT, timestep, history, close-position, option-intent, and backtesting-broker suites: 98 passed, 3 skipped, 1 xpassed.
  • New regression files: Ruff clean; changed Python files compile successfully.
  • Sphinx HTML build succeeded. Its 20 warnings are pre-existing autodoc/docstring warnings outside this change.
  • The monolithic local suite is not a valid sandbox signal because an unrelated managed-agent test writes its FRED cache to a read-only default cache directory. GitHub sharded CI is the merge gate.

Scope

This does not include previously merged speed work or #1161 fill-ownership/CVNA changes.

Summary by CodeRabbit

  • Bug Fixes

    • Crypto-futures positions now close reliably with correct reduce-only orders, including partial closes and backtests.
    • Live Bitunix and Coinbase historical data now retrieves complete requested bar ranges and reports a clear error when insufficient history is available.
    • Invalid or empty orders are rejected safely.
  • Documentation

    • Added guidance on historical bar retrieval, crypto-futures closing behavior, partial closes, and data completeness.
  • Chores

    • Updated the package version to 4.5.91.
    • Release evaluation freshness can now be restored from previous successful runs.

Review Change Stack

📝 Walkthrough

Walkthrough

The release workflow restores reusable eval freshness. Bitunix and CCXT history retrieval now paginate by timeframe and reject short results. Crypto-futures close paths create side-correct reduce-only orders and reject null submissions. Version and documentation updates record these changes.

Changes

Cross-workflow eval freshness

Layer / File(s) Summary
Freshness artifact restoration
scripts/restore_agent_eval_freshness.py
Adds GitHub API queries, artifact validation, secure redirects, and atomic freshness-state restoration.
Release workflow integration and validation
.github/workflows/release.yml, tests/test_agent_eval_harness.py, setup.py, CHANGELOG.md, docs/BROKER_ORDER_SEMANTICS.md
Adds artifact-read permission and restores freshness before stale-eval processing. Tests cover ordering, permissions, archive validation, and artifact selection. The release metadata records the changes.

Complete live crypto history

Layer / File(s) Summary
Native interval and completeness contracts
lumibot/data_sources/bitunix_data.py, lumibot/strategies/strategy.py
Adds native timestep detection and preserves supported multi-timeframe requests.
Bitunix paginated retrieval
lumibot/data_sources/bitunix_data.py, tests/test_live_crypto_history_pagination.py, docsrc/brokers.bitunix.rst
Uses bounded 200-candle windows, timestamp pagination, deduplication, and short-history errors.
CCXT cursor pagination
lumibot/data_sources/ccxt_data.py, tests/test_live_crypto_history_pagination.py, docsrc/brokers.ccxt.coinbase.rst
Derives page spans from the timeframe, advances inclusive cursors, and rejects empty or short results.
History behavior documentation
docs/BROKER_ORDER_SEMANTICS.md
Documents pagination and live history completeness requirements.

Crypto-futures position closing

Layer / File(s) Summary
Reduce-only close order construction
lumibot/brokers/broker.py, docsrc/brokers.bitunix.rst, docsrc/faq.rst
Builds side-correct fallback orders, validates fractions, scales partial closes, and filters null orders.
Null-order submission guards
lumibot/brokers/broker.py, lumibot/backtesting/backtesting_broker.py
Rejects null orders before submission processing.
Close behavior validation and invariants
tests/test_crypto_future_close_position.py, docs/BROKER_ORDER_SEMANTICS.md, CHANGELOG.md
Tests close direction, reduction, partial quantities, flattening, stock behavior, and bulk closing. Documentation records the close invariant.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to f5501

Valid history requests can fail, some close or batch-order paths can use invalid data, and release evaluations may be reused from an unrelated ref. These should be resolved before merge.

Inline comments:
In `@lumibot/brokers/broker.py`:
- Line 2942: The close-position fallback in Broker.close_position must use the
quote asset belonging to strategy_name rather than an arbitrary value from the
broker-wide quote_assets set. Resolve that strategy-specific asset, or leave
quote unset when the provider derives it from the instrument, and add a
regression test covering two strategies with different quote assets.
- Around line 2647-2648: Update submit_orders to reject None entries before
calling resolve_option_order_intent(), using the same null-order validation as
submit_order. Ensure submit_orders([None]) raises the intended ValueError
instead of dispatching to _submit_order with a null order.

In `@lumibot/data_sources/bitunix_data.py`:
- Around line 224-225: Update the empty-response handling in the Bitunix data
retrieval flow to raise the same ValueError used for short candle frames instead
of returning None. Include the returned and requested counts in the error,
preserving the existing short-history contract.
- Around line 189-190: Update BitunixData.get_historical_prices() and
CcxtData.get_barset_from_api() to widen their lower time bounds when pagination
returns too few unique candles, continuing backward requests while merging and
deduplicating results until the requested count is reached or the provider’s
documented history boundary is reached. Add regression tests covering sparse
markets for both providers.

In `@scripts/restore_agent_eval_freshness.py`:
- Around line 90-91: Bind restore() to the trusted qualification ref by deriving
it from the release tag or passing the exact trusted commit, then filter
workflow runs by head_branch or head_sha before downloading artifacts. Update
the restore workflow invocation in .github/workflows/release.yml accordingly,
and revise tests in tests/test_agent_eval_harness.py to include trusted metadata
plus a newer valid artifact from another branch that is ignored.

In `@tests/test_crypto_future_close_position.py`:
- Around line 22-29: Add focused parameterized tests covering that fraction
rejects zero, negative, and greater-than-one values, and add direct tests
verifying Broker.submit_order() and BacktestingBroker._submit_order() reject
None. Assert each public error contract explicitly while preserving the existing
close-position test.

Reject null entries in submit_orders.

submit_orders([None]) bypasses submit_order() and reaches ProjectX._submit_order(None) through the generic fallback. That method dereferences order.asset, causing a null-order failure. Add the guard before resolve_option_order_intent().

Proposed fix
 def submit_orders(self, orders, **kwargs) -> Union[Order, list[Order]]:
     """Submit orders"""
     resolved_orders = []

💡 Result:

In the context of the Lumibot trading framework, quote_assets and close_position are related components used for managing trading operations and portfolio valuation [1][2]. quote_assets: This refers to a collection of assets (typically a set) defined within a broker instance that represent the base currencies or cash equivalents used to value positions and measure portfolio performance (e.g., USDT, USD, USDC) [1][2][3]. The quote asset is the currency in which a strategy's portfolio value is denominated [1]. When a position is closed, the framework may use these defined quote assets to determine the currency in which the trade proceeds are settled [2]. close_position: This is a method available in both the strategy and broker classes used to exit an open trading position [1][2]. - Strategy Level: When calling self.close_position(asset) within a strategy, it triggers the corresponding broker's close_position method for that specific asset [1]. It supports closing a fraction of the position (default is 1.0, or 100%) [1][2]. - Broker Level: The broker implementation executes the logic to close the position [2]. For standard assets, this is typically achieved by submitting a market sell order [1][2]. For specific crypto futures brokers (such as Bitunix), the implementation may utilize specialized, high-performance API endpoints, such as a flash-close or reduce-only order, to exit the position immediately [1][4]. If no open position exists for the specified asset, the close_position method generally does not take any action [1][2].

Scope the close-order quote to strategy_name.

Broker.close_position selects an arbitrary item from the broker-wide quote_assets set. For crypto futures, Position.get_selling_order returns None, so the fallback Order stores that unrelated quote asset. Pass the owning strategy’s quote asset, or leave quote unset when the provider derives it from the instrument. Add a regression test with two strategies that use different quote assets.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Expand the history window when sparse candles leave the result short.

BitunixData.get_historical_prices() and CcxtData.get_barset_from_api() can return fewer unique candles because they start at fixed start_ms/since bounds, then raise before requesting older data. Both provider contracts support widening those lower bounds. Continue pagination backward, merge and deduplicate the results, and stop only after reaching the requested count or the provider’s documented history boundary. Add sparse-market regression tests for both providers.

Raise the short-history error for an empty response.

Line 225 returns None when Bitunix returns no candles. This bypasses the new contract that insufficient exchange history raises an error with returned and requested counts. Use the same ValueError path as the short-frame case.

Bind restored eval artifacts to the trusted qualification ref.

The release workflow is tag-driven, but restore() accepts any successful manual run with a valid-shaped artifact. It does not check head_branch or head_sha. A run from another ref can therefore provide freshness data that causes the tagged release gate to skip real-model evals.

Derive the expected qualification ref from the release tag or pass its exact trusted commit. Filter runs before downloading artifacts, and update the test fixtures to include trusted metadata plus a newer valid artifact from another branch that must be ignored.

Add tests for the new rejection behavior.

No test asserts that fraction rejects zero, negative, and greater-than-one values. No test directly asserts the new None rejection in Broker.submit_order() or BacktestingBroker._submit_order().

Add focused parameterized tests for these public error contracts.

As per coding guidelines, “Add unit tests for any new functionality.”
