How we work
From idea to live trading in four steps
01
Discovery
We map your strategies, venues, data needs and risk limits, and agree on a scope with fixed milestones.
02
Build & backtest
We develop in short iterations with automated tests and replay historical data against the exact live code path.
03
Paper & staged go-live
Paper trading, then small size with hard risk limits, then full size, with you in control at every gate.
04
Handover & improve
Full documentation and handover, then a steady cadence of performance and feature work if you want it.
Why eFinance
Built by engineers who have run live money
We know the difference between a strategy that looks good in a notebook and one that survives a flash crash, a broker outage or a stale data feed. Every system we ship is designed with that in mind.
- Deterministic, replayable systems: the same code path for backtest, paper and live
- Hard pre-trade risk checks and independent kill switches on every deployment
- Australian-based team, aligned to ASX, Asian and US sessions
- Source code and infrastructure are yours. No lock-in, full documentation.
- Fixed-price projects or retained engineering by the day

FAQ
Common questions
Do you provide trading signals or financial advice?
No. eFinance is a technology services provider. We build, host and support the systems that run your strategies, but we do not provide financial product advice, recommend trades or manage money. You remain responsible for your trading decisions and any licensing that applies to your activity.
Who owns the code you write for us?
You do. All custom code, configuration and documentation produced under a project is assigned to you on payment. We can also work inside your own repositories from day one.
Can you work with an existing bot or MetaTrader EA?
Yes. Much of our work is hardening and extending systems that already exist, including MQL4/5 expert advisors, NinjaTrader strategies, Python bots and bespoke C++ engines.
How do you keep our strategies and API keys confidential?
We sign an NDA before any discovery, keep secrets in a managed vault with per-engineer access and audit logs, and never hold withdrawal permissions on exchange keys.
What does a project cost?
Development projects are quoted fixed-price after a short discovery phase, and ongoing work is billed by the day. Get in touch for a quote.
