the order indicator to assign.
indicators : List[BaseOrderIndicator]
the list of all inner indicators.
metrics : Union[str, List[str]]
all metrics needs to be sumed.

Solutions
- Implement the `sum_all_indicators` method in your subclass before calling it.
- Use a concrete class that provides `sum_all_indicators` instead of the abstract base.
When it happens
Trigger: This error is raised at qlib/backtest/high_performance_ds.py:418 when the guard condition fails: "Please implement the 'sum_all_indicators' method". It triggers when the code path receives input or a state that violates the precondition checked at this point — e.g. an unimplemented abstract method being called, an unsupported argument type/value, or an invalid configuration. To avoid it, satisfy the documented precondition before this call: implement the required method in your subclass, or pass a supported value of the expected type as described by the message.
Common situations: See trigger scenarios.
