Computed / Derived — ecn-tax — Data Flow
Why this page is structured this way: This is the field-first view for the computed/derived
[ecn-tax]pseudo-section. These fields don’t exist at KYC onboarding time; they’re produced by operations (trade execution, margin computation, settlement files, etc.). To see the same data from the destination’s perspective, jump from the atlas overview.
- 5 unique fields in this section.
- 5 field-destination relationships total.
