Pre-Trade Handoff Intake

QuantLab now supports a bounded intake for external calculadora_riego_trading handoff artifacts.

This surface exists to consume upstream planning artifacts without reintroducing the broader pretrade runtime that was intentionally reverted.

Boundary

The integration rule remains:

  • the calculator proposes
  • QuantLab validates
  • QuantLab decides
  • QuantLab executes

This means the handoff artifact is treated as external input only.

It does not:

  • grant execution authority
  • bypass ExecutionPolicy
  • create broker approval
  • create paper or broker sessions

CLI

Validate a bounded handoff artifact:

python main.py --pretrade-handoff-validate path/to/quantlab_handoff.json

Optionally choose where the local validation artifact should be written:

python main.py \
  --pretrade-handoff-validate path/to/quantlab_handoff.json \
  --pretrade-handoff-validation-outdir outputs/pretrade_handoff/demo

Output

QuantLab writes:

pretrade_handoff_validation.json

The validation artifact records:

  • source artifact path
  • contract metadata
  • pre-trade context
  • trade-plan metadata
  • explicit rejection reasons when the handoff is incomplete or malformed
  • a local QuantLab-owned readiness flag for future draft execution bridging

Current scope

This intake is intentionally narrow.

It validates:

  • handoff contract type and version
  • source lineage metadata
  • symbol
  • venue
  • side
  • trade-plan contract metadata consistency

It does not yet:

  • create a canonical pretrade session
  • bridge into draft ExecutionIntent
  • run broader policy approval
  • touch any broker submit surface
