Desk software · Agency MBS

The software agency MBS desks run on.

Blotter, positions, pricing, P&L, sales flow. We built these systems at a primary dealer. Now we build them for desks that don't have a 200-person technology floor.

Products

Four systems. One data model.

Each product runs standalone. Together they share one position and flow database, so the blotter, the P&L, and the salesperson's screen never disagree.

LEDGER blotter · positions

IN PRODUCTION · 6 DESKS

The system of record. Trade capture, real-time positions, TBA allocation workflow. Replaces the position spreadsheet before it breaks in a fast market.

  • Positions by coupon, vintage, TBA vs. pool vs. hedge
  • 48-hour-day allocation: EPN in, good-delivery checks, variance handled
  • FICC netting and fails tracking built in

ENGINE pricing · P&L · risk

IN PRODUCTION · 3 DESKS

Intraday P&L and pricing on Ledger positions. Attribution that says why: carry, curve, basis, prepay. Feeds your risk stack. It does not pretend to be your risk stack.

  • Intraday P&L with attribution traders accept
  • Pluggable models: Yield Book, AD&Co, internal
  • Limits and exposure feeds to firm risk, real time

FLOW sales CRM

PILOT · 2 DEALERS

A CRM built around trade history, not contact notes. Every print, every axe, every client inquiry in one place. The matching engine says which client should see which bond.

  • Client flow history as the core object
  • Axe-to-client matching from past flow
  • Runs generated and distributed automatically

ROLL financing analytics

FREE TOOL + SUBSCRIPTION

Roll breakeven and implied financing across the coupon stack. The single-roll calculator is public and free. The live monitor across all coupons is the product.

  • Breakeven drop, implied repo, verdict, carry breakdown
  • Convention-correct: 30/360 coupon, act/360 financing
  • No fabricated levels. Your inputs, audited arithmetic
Services

We also build to spec.

Most engagements start as a build and end as a subscription. We deliver against deadlines because we have done this under OCC deadlines.

01

Desk systems built to order

Blotter, positions, limit monitoring, pricing. Scoped in weeks, delivered in months, documented so your people can run it.

02

Integration

EPN, FICC, TRACE, Tradeweb, internal risk and books-and-records. We speak the protocols and the conventions: 32nds, 48-hour day, good delivery.

03

Off the spreadsheet, without stopping the desk

Parallel-run migration from Excel position management to a system of record. The desk trades through the cutover.
