Calculate Net Weight

portfolio.net_weight

ProductionBounded custom (Class B)Deterministicstrictinstantv1.0.0

No network

Overview

Calculate exact bounded net weight from caller-supplied portfolio values. Every denominator, weight, and component is explicit.

You receive deterministic portfolio ratio or P&L evidence without hidden assumptions for portfolio.net_weight.

Reliability

DECIMAL_INVALID means a decimal is malformed or over limit; correct it. PORTFOLIO_INPUT_INVALID means weights or components violate the closed domain; correct them. ZERO_DENOMINATOR means division is undefined; supply a valid denominator. ITEM_LIMIT_EXCEEDED means a collection exceeds 10,000; reduce input. This guidance applies specifically to portfolio.net_weight.

Context footprint

The compact result replaces repeated prompt arithmetic for portfolio.net_weight. A successful call costs 1 execution credit.

When to use it

When a signed position versus portfolio net must become net weight.

When absolute gross weight is required rather than the signed net weight.
