Algorithmic Trading Development in Ireland

Systematic, rule-based algorithmic trading systems.

Why Zefinx

  • Native MQL4 & MQL5 engineering — no wrappers, no bloat
  • Realistic multi-year backtesting and forward-test guidance
  • Strict risk controls: lot sizing, drawdown caps, session & news filters
  • Full source-code ownership with an optional NDA

We build systematic algorithmic trading software that turns quantitative rules into automated execution — with rigorous backtesting, risk control and transparent, auditable logic. We support Irish traders and businesses remotely, overlapping with GMT/IST hours, quoting in EUR, and keeping delivery aligned to how you trade in Ireland.

Our delivery process

3. Backtesting & optimisation

We validate across historical data relevant to Ireland, tune parameters and check for overfitting.

4. Delivery & deployment

You receive the source, a usage guide and help deploying to a VPS for stable GMT/IST execution.

5. Support & iteration

Post-delivery tuning, updates and new-feature work keep your automation aligned with changing markets.

Frequently asked questions

Algorithmic trading uses pre-defined, coded rules to enter and exit trades automatically, removing emotion and enforcing consistent risk management across every trade.

Yes. We build systems that run several strategies or symbols at once with a shared risk engine controlling total exposure and correlation.

Running your own automated system on your account is standard practice. We build development-only tools and give no financial advice; always follow guidance from the Central Bank of Ireland.

We use in-sample optimisation plus out-of-sample and walk-forward testing to reduce overfitting, then forward-test before live deployment.

A fixed quote in EUR follows scoping, based on the number of strategies, data sources and risk rules involved.
