A systematic approach to every basis point

Our four-stage methodology is designed to identify, filter, and execute opportunities with the precision of an institutional desk — without the institutional overhead.

Step 01 — Regime Mapping

Market State
Classification

Proprietary regime detection classifies the market into four structural states — trending bull, trending bear, mean-reverting, and transitional — adjusting execution parameters dynamically for each.

4 Regime
classifications
Step 02 — Quantitative Filtration

Multi-Factor
Signal Screening

Each potential trade passes through a multi-factor validation model: VWAP deviation, order book depth, momentum confirmation, and volatility regime alignment — all before a single order is placed.

7 Validation
factors
Step 03 — Precision Execution

Midpoint Limit
Order Protocol

All orders are placed at the exact bid-ask midpoint via limit orders. This eliminates spread consumption, reduces market impact to near-zero, and ensures we never pay more than the fair theoretical price.

Step 04 — Systematic Audit

Continuous
Performance Attribution

Every executed trade is logged against its pre-trade benchmark. Execution quality scores, slippage attribution, and fill distribution analysis feed back into the model on a rolling 30-day basis.

Bid-Ask Midpoint
Execution Precision

By placing limit orders at the theoretical midpoint, we capture half the spread on every trade — a structural edge that compounds materially over high-frequency execution cycles.

B

Bid Side

The highest price a buyer will pay. Market sells hit this price — consuming the spread.

M

Midpoint

Our target. The fair theoretical price between bid and ask — accessible only via limit orders with discipline.

A

Ask Side

The lowest price a seller accepts. Market buys hit this price — consuming the spread in the other direction.

¹ Midpoint fill rate: percentage of orders executed at or within 0.5bps of the theoretical bid-ask midpoint at time of submission.
² Cost vs Market Order: improvement in basis points versus equivalent same-direction market order, measured against T+0 NBBO at time of submission.
³ Execution Quality: internal score combining fill rate, slippage, and timing efficiency. Past execution results do not guarantee future performance.

Our competitive advantage is structural: the midpoint limit order protocol is not a strategy overlay — it is the foundation of every trade we make. This discipline, applied systematically across thousands of executions, compounds into material edge.

We engage selectively with qualified institutional counterparties for research exchange, execution benchmarking, and strategic dialogue. External capital inquiries are subject to strict regulatory vetting under Swedish and EU financial frameworks.
