QuantConnect.Lean.Engine.Results.Analysis.Analyses.InsufficientBuyingPowerOrderResponseErrorAnalysis

Bases: OrderResponseErrorAnalysis

Detects insufficient-buying-power order rejections.

issue

issue: str

Gets a description of the insufficient buying power issue.

weight

weight: int

Gets the priority weight for this analysis.

expected_message_text

expected_message_text: List[str]

Gets the message fragment that identifies an insufficient buying power error.

This codeEntityType is protected.

solutions

solutions(language: Language) -> List[str]

Gets solutions for ensuring sufficient margin or adjusting the buying power buffer.

This codeEntityType is protected.

single_response

single_response(
    sample: Any, solutions: Sequence[str] = None
) -> Sequence[Analysis]

single_response(
    sample: Any,
    count: Optional[int],
    solutions: Sequence[str] = None,
) -> Sequence[Analysis]

Wraps a single QuantConnect.Analysis in a one-element read-only list.

create_aggregated_response

create_aggregated_response(
    responses: List[Analysis],
) -> Sequence[Analysis]

Filters responses to those with solutions, prefixes the class name, and returns a flat list.

This codeEntityType is protected.

format_code

format_code(code: str, language: Language) -> str

Formats the specified code string according to the conventions of the given programming language.

This codeEntityType is protected.

run

run(
    parameters: ResultsAnalysisRunParameters,
) -> Sequence[Analysis]

run(
    order_events: List[OrderEvent], language: Language
) -> Sequence[Analysis]

Runs the analysis against a list of order events, extracting matching invalid-event messages and delegating to the message-based MessageAnalysis.run(IReadOnlyList{string}, Language) overload.

Parameters:

Name	Type	Description	Default
order_events	Optional[List[OrderEvent]]	The order events from the backtest result.	None
language	Optional[Language]	The programming language the algorithm is written in.	None

Returns:

Type	Description
Sequence[Analysis]	Analysis results when any matching order response errors are found.

match

match(
    messages: Sequence[str], expected_messages: List[str]
) -> Iterable[str]

Returns messages from messages that contain all strings in expected_messages (case-insensitive).

This codeEntityType is protected.

get_matching_order_events_messages

get_matching_order_events_messages(
    order_events: List[OrderEvent],
) -> Iterable[str]

Filters order_events to those with OrderStatus.INVALID status whose message contains all MessageAnalysis.expected_message_text fragments.

This codeEntityType is protected.

Parameters:

Name	Type	Description	Default
order_events	List[OrderEvent]	The order events to inspect.	required

Returns:

Type	Description
Iterable[str]	An enumerable of matching message strings.
