Money Market

sabi-md

The largest pack in the catalogue. The desk trades against its own inventory: it opens a position, sells to the client and keeps the maturity calendar and coupon interest, with the module’s 24 formulas.

Anchor test

Opening desk inventory generates 4 entries and the sale to the client 16, with the real rules of the MD module; a sale without inventory is rejected, as in the legacy system.

A test that does not fail when the code is wrong does not count. Every pack is anchored to an oracle traced by hand against the legacy catalogue, entry by entry.
