State 010 extends functional behavior with pricing-aware fields and valuation calculations.

Entity Impact

• Added:
  • Trade price capture at execution/settlement time.
  • Position valuation fields (market value, cost basis, P&L projections).

• Removed: none

Notes

This state introduces additive functional data for valuation while retaining compatibility with existing account/trade/position workflow boundaries.
