About this work

Markets are wild.
Execution must be engineered.

Evrydiki is a boutique systematic trading firm based in Nicosia, Cyprus. We design rule-based strategies for liquid futures, size positions under fractional Kelly with strict drawdown limits, and route every trade through automated execution. Human oversight supervises the system; it does not override it.

Two intellectual influences

Benoît Mandelbrot

Markets are fractal.

Price moves do not follow a bell curve. Extreme events happen more often, and concentrate in clusters, than Gaussian models predict. We size positions, set stops, and budget risk under that assumption — not against the textbook one.

Ray Dalio

Principles, not instinct.

Every recurring decision should be encoded as an explicit rule, examined when it fails, and revised in the open. Discretion is reserved for the few decisions that must be made before a rule can be written.

Methodology open. Signals private.

What we publish.

The thinking. Working papers on position sizing, drawdown construction, regime detection, and risk budgeting. Notes on why a model was retired or revised. Honest post-mortems of what worked and what did not.

What we keep private.

The signals. Live model parameters, current positions, entry and exit triggers, and any data that would erode the edge if disseminated. We share the framework so the work can be evaluated on principle. We do not share the trades.

Reserved for engaged investors

In practice

By selection

We engage a small number of qualified investors at any given time. Capacity is finite; alignment is required.

By appointment

Conversations begin only after a fit on principles, ticket size, and jurisdiction. No cold calls, no public marketing.

By process

Every step — from research, to onboarding, to monthly reporting — runs on a written process. If we cannot describe it, we do not do it.

Engagement

If a fit exists, the door opens.

We do not publish a phone number or hold open hours. Qualified investors who would like to begin a conversation submit a short Request Access form. We respond within two business days — directly, either way.
