Product engine

OTC / FX

An engine for running a two-sided OTC and FX desk. It prices quotes from the rate sources you connect, handles the request-for-quote exchange with your clients, applies the spread and markup you define, and books each executed trade on the same ledger as the rest of the stack.

What it includes

  • Quote engine with live quotations.
  • RFQ workflow from request through fill.
  • Spread and markup configuration per pair.
  • LP and exchange connectors, ours or your own.
  • Trade settlement against the system of record.
  • Ledger sync, so every trade posts to the immutable core.

On one ledger with the rest of the stack

Every quote the engine returns carries its provenance: the rate source it drew from and the spread and markup you applied on top, recorded with the quote rather than reconstructed after the fill. When a trade executes, that lineage stays attached to it, so any price the desk showed can be traced back to the feed and the policy version behind it.

A settled trade and the position it opens post to the same ledger your reporting reads. The desk does not keep its own book that a back office later has to match: the blotter and the accounting are one record, and the spread you earned shows up where P&L is computed without a separate feed from the trading system.
