# Data Model: Pricing Awareness and Market Data Streaming

> For the complete documentation index, see [llms.txt](https://deploy-preview-472--lucky-concha-f3599f.netlify.app/llms.txt).

## Scope

State `008` 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).
    *   Price quote freshness field (`asOf`) on snapshot and stream payloads for deterministic client-side ordering.
*   Changed:
    *   Position aggregation logic includes price-aware computation outputs.
    *   UI bootstrap flow combines snapshot seed + stream continuation using `max(asOf)` merge semantics per ticker.
*   Removed: none

## Notes

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