Calculate Long and Short Exposure

portfolio.long_short_exposure

ProductionBounded custom (Class B)Deterministicstrictinstantv1.0.0

No network

Overview

Perform bounded exact-decimal long short exposure with every position input explicit. Closed bounded inputs and no inferred market data apply.

You receive deterministic position or exposure evidence without hidden portfolio assumptions for portfolio.long_short_exposure.

Reliability

DECIMAL_INVALID means a decimal is malformed or over limit; correct it. PORTFOLIO_INPUT_INVALID means a factor, collection, or identifier violates its domain; correct it. DUPLICATE_ID means two records use the same identifier and grouping would be ambiguous; supply unique record ids before retrying. CURRENCY_INVALID means an ISO code is unsupported or not uppercase; correct it. ITEM_LIMIT_EXCEEDED means a collection exceeds 10,000; reduce input. This guidance applies specifically to portfolio.long_short_exposure.

Context footprint

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

When to use it

When signed exposures must be split into long and short totals.

When you need one net figure, not separate long and short totals.
