Execution domain

Language: English · 简体中文

quant_execution_engine provides reusable execution-domain components: target-file normalization, typed order and portfolio models, wire codecs, broker-neutral capability contracts, and deterministic simulated execution.

The public package does not provide a standalone production CLI. Production broker adapters and their commands belong to private runtime environments. Broker SDK integrations, credentials, live-trading configuration, audit storage, and production runtime are not part of this public package.

The compatibility namespace remains during migration from the former execution repository.

Output paths

Execution audit, state, and evidence default to the user state directory under quant-platform/execution. If DATA_PLATFORM_ROOT is set, the default becomes $DATA_PLATFORM_ROOT/quant-platform/execution. QUANT_PLATFORM_OUTPUT_ROOT sets a platform output root, while the more specific QEXEC_OUTPUTS_DIR sets a run directory.

Precedence, from highest to lowest, is QEXEC_OUTPUTS_DIR, QUANT_PLATFORM_OUTPUT_ROOT, DATA_PLATFORM_ROOT, then the XDG user state directory. A path explicitly passed to a state-store or reporting API takes precedence for that call. These defaults do not create an outputs directory in the Git checkout.
