Strategy Exceptions

Namespace: MZpack.NT8.Algo

Class	Base	When Thrown
StrategyException	Exception	Abstract base for all MZpack strategy exceptions
StrategyPrepareException	StrategyException	Strategy preparation fails (e.g., missing indicators, invalid configuration)

StrategyPrepareException message format: "Strategy prepare error. {details}"

Decision Tree Exceptions

Namespace: MZpack.NT8.Algo

Class	Base	When Thrown
DecisionTreeException	StrategyException	Abstract base for decision tree validation errors
DecisionTreeInvalidStructureException	DecisionTreeException	Decision tree has structural issues (e.g., empty root, invalid node arrangement)
DecisionTreeSignalChartRangeIsNullException	DecisionTreeException	Signal's ChartRange was not assigned in OnCalculate() while using tree range validation
DecisionTreeSignalChartRangeIsInvalidException	DecisionTreeException	Signal's ChartRange is invalid (e.g., out of bounds) while using tree range validation

Message formats:

• "Invalid structure of the decision tree. {details}"
• "Chart range of validated signal/filter is null. {details}"
• "Chart range of validated signal/filter is invalid. {details}"

Export Exceptions

Namespace: MZpack.NT8.Algo.DataExport

Class	Base	When Thrown
ExportException	StrategyException	Abstract base for data export errors
DataExportNullArgumentsException	StrategyException	ExportArgs is null
DataExportDuplicatedIndValueException	ExportException	Same IndValue added to schema twice
DataExportColumnNotFoundException	ExportException	Referenced column name not found in schema
DataExportNoHandlerForIndValueException	ExportException	No handler registered for the specified IndValue in the indicator
DataExportNoChartObjectDescriptorException	ExportException	ValueDescriptor with DrawingObject source has no ChartObjectDescriptor
DataExportNoHandlerForCustomValueException	ExportException	ValueDescriptor with Calculate source has no delegate assigned
DataExportEmptyPipelineException	ExportException	Pipeline.Init() called with no exports added
DataExportGranularityException	ExportException	Unsupported ExportGranularity for the data source

Message formats:

• "Null export arguments"
• "Duplicated indicator value '{indValue}'"
• "Colum not found '{column}'" (typo preserved from source)
• "No handler for indicator value '{indValue}'"
• "No descriptor for chart object defined"
• "No handler for custom value '{name}'"
• "Data export pipeline is empty"
• "Granularity {granularity} not supported for the export."
