Module dynamic 

TaEngine-based dynamic indicator calculation.

This module provides a bridge between the streaming motosan-ta-stream engine and the existing TechnicalIndicators struct. It enables two workflows:

1. calculate_snapshot – feeds candles through a TaEngine and returns a TaSnapshot containing all indicator values.
2. snapshot_to_indicators – converts a TaSnapshot back into the legacy TechnicalIndicators struct for backward compatibility with the rule engine.

Helper functions get_snapshot_value / get_snapshot_sub_value provide direct access to individual indicator values inside a snapshot.

Functions

build_default_engine

Build a TaEngine with the standard set of indicators used by strategy templates. The returned engine covers every indicator present in TechnicalIndicators.

calculate_snapshot

Feed a slice of candles through a TaEngine and return the final snapshot.

get_snapshot_sub_value

Get a named sub-value from a multi-value indicator.

get_snapshot_value

Get a single (or primary) value from a TaSnapshot by indicator key.

snapshot_to_indicators

Convert a TaSnapshot into the legacy TechnicalIndicators struct.
