triangulated-fx-rates

separate

Reference for multi-hop / triangulated currency conversion on batch rate tapes. When a rate row carries an explicit "via" currency, the row's rate is only one leg of the conversion, and the via currency may ITSELF be quoted through another via — so the effective rate is the product of every leg, resolved by walking the chain until a direct quote is reached. Useful when an FX feed lists some pairs directly to the reporting currency and others as triangulated (or doubly-triangulated) quotes through vehicle currencies.

When to use

• multi-hop currency conversion
• triangulated FX rates
• resolving via chains
• batch rate tape processing
• calculating effective rates
• handling doubly-triangulated quotes

When not to use

• direct currency conversion without via columns
• real-time FX feed processing
• currency code validation
