Software Engineering & Automation

We build the software. You run it.

J&D Vantage Quant is a software development practice for financial markets. We write, test and document trading and automation software to your specification — then hand you the code. It runs on your infrastructure, under your credentials, on your own broker account.

We are an engineering firm, not a market participant acting for others. We do not trade on anyone's behalf, we do not hold or manage client money, and we do not advise on what to buy or sell.

01 — Capabilities

Engineering work, across markets and beyond them

Most of our work is automating a process that someone is currently doing by hand. Frequently that process involves a market — Indian equities and derivatives, forex, or commodities — but the discipline is the same wherever it is applied.

01

Algorithm development

You describe the rules. We turn them into tested, readable, documented code that does exactly what the specification says — and nothing it does not.

PythonC++MQL5Pine
02

Backtesting & research tools

Simulation harnesses that replay historical data against a rule set, with realistic cost and slippage modelling, so you can evaluate your own idea on your own data.

SimulationCost modelsReporting
03

Broker & exchange API integration

Order routing, position reconciliation, authentication and failure handling against broker APIs — built against your credentials, never ours.

RESTWebSocketFIX
04

Dashboards & monitoring

Web dashboards that show you what your own systems are doing — health checks, alerting, logs and operational reporting you can read at a glance.

Web appsAlertingLogging
05

Data pipelines

Collecting, cleaning, storing and serving market and business data reliably, with the gaps and errors surfaced rather than silently filled in.

06

General business automation

Not every problem is a market problem. Reporting, reconciliation, scheduling, document generation — if it is repetitive and rule-based, it can be automated.

Where our work stops

This distinction matters, so we state it on the front page rather than burying it in a footer. We are paid to write software. We are not paid on, and take no share of, what that software subsequently does.

✓ What we do

  • Write software to a written client specification
  • Test it, document it and hand over the source code
  • Help the client deploy it on their own servers and accounts
  • Fix defects and ship upgrades under a maintenance agreement
  • Invoice a fixed professional fee for the engineering work

✕ What we do not do

  • Accept, hold, pool or manage any client money
  • Place orders on a client's behalf or operate their account
  • Advise on which instruments to buy or sell, or when
  • Take any share of trading profits, commission or performance fee
  • Publish, promise or imply any return, yield or performance figure
Plainly stated Our fee is for engineering time and deliverables. It is the same whether the software the client runs makes money or loses it, and we have no visibility into and no claim on that outcome. We are not a broker, an investment adviser, a research analyst, a portfolio manager or a fund of any kind, and we do not hold ourselves out as one. Read the full compliance position →
03 — How we work

A documented engagement, end to end

Every project runs against a written scope and is invoiced against delivered milestones. No retainers against future trading, no open-ended arrangements.

STEP 01

Specification

We write down exactly what the software must do, in language you can check, and agree it before any code is written.

STEP 02

Build & test

Development against that specification, with a test suite and, where relevant, a simulation run on your historical data.

STEP 03

Handover

Source code, documentation and deployment notes are delivered to you. You hold the credentials and control the infrastructure.

STEP 04

Maintenance

Optional ongoing agreement for defect fixes, upgrades and changes as your requirements evolve, billed separately.

04 — Commercials

How an engagement is priced

MODEL 01

One-time development fee

A fixed fee, agreed in advance against a written scope, for building and delivering the software. Invoiced on milestones or on delivery. Ownership of the delivered code passes to the client on final payment.

MODEL 02

Maintenance & upgrades

An optional agreement covering defect fixes, upgrades and enhancements to software already delivered. Billed as a periodic fee or per change request, quoted before work begins.

No variable component There is no third pricing model. We do not offer revenue sharing, profit sharing, performance fees, commission, or any arrangement whose value depends on a client's trading outcome.
