Venue-aware smart order routing
Routes across venues using spread, depth, maker/taker fees, and historical adverse selection. Slicing respects time-in-force and minimum quote sizes to avoid brittle rejects.

Capabilities for Disciplined, Auditable Execution
A practical toolkit for crypto and FX desks: venue-aware routing, stringent pre-trade checks, complete auditability, and low-latency gateways. Built to reduce slippage, not to sell slogans.
No credit card required. Results vary; based on client-reported fills.

Execution features
Concrete capabilities traders can verify in fills, logs, and PnL attribution—nothing vague.
Strategy library with walk-forward
40+ strategies spanning momentum, mean-reversion, and market-making. Each uses walk-forward retraining to catch drift and triggers a cooldown after variance spikes.
Pre-trade checks and guardrails
Exposure caps, instrument limits, and drawdown budgets block risky orders. Every block writes a deterministic reason code with inputs used at decision time.
Low-latency gateways
Median 12ms round-trip in London PoP with idempotent API calls and circuit breaker patterns to contain venue issues without cascading failures.
Audit trail and PnL attribution
Signal, route, slice, and fill decisions persist to an immutable log. Attribution splits model edge from execution friction to guide changes.
Key security and roles
API keys are encrypted at rest, decrypted just-in-time, and scoped to trade-only. Role controls govern who can arm, pause, or change budgets.
Execution architecture
Designed to be resilient when markets get noisy. The stack favors determinism, graceful degradation, and transparent failure modes.
Reliability patterns
- Idempotent API calls prevent duplicate orders during retries; correlation IDs trace every slice.
- Circuit breaker pattern isolates venue outages; backoff and half-open tests avoid thundering herds.
- P99 latency tracked per venue and per route; alerts trigger when tails widen beyond budget.
- Dead-letter queue for rejects; replay requires explicit approval with full reason codes attached.
Deployment and safety
- Blue-green deployment for gateways; rollback under 30 seconds with state handover checks.
- Secrets sealed with role-based access; just-in-time decryption for execution only.
- Multi-tenancy isolation by account and venue; throttles applied per bucket to avoid cross-talk.
- Immutable audit ledger with reason codes, computed inputs, and book snapshots for every decision.
What this solves
The architecture reduces duplicate rejects, contains venue-specific failures, and makes post-trade review measurable. It is infrastructure for consistent, methodical execution—no guarantees of returns, only guardrails and clarity.
Risk controls and compliance posture
Controls that keep exposure bounded and decisions transparent. Built for internal oversight and external review.
Pre-trade guardrails
Instrument caps, account-level exposure limits, and drawdown budgets run before every order. If a rule trips, routing pauses and the reason code is logged for review.
Post-trade transparency
Fills, cancel-replaces, and rejects are attributed to model edge versus execution. Walk-forward validation highlights drift before capital is re-allocated.

Quick checklist for desk leads
- Are idempotency keys present on every order slice in logs?
- Do reason codes show computed exposure and limits when blocks occur?
- Is P99 latency within budget for the venues you route most?
- Does walk-forward performance align with recent live PnL distribution?
- Are throttle rules documented for macro prints and burst traffic?

Evan has spent the last eleven years building routing logic for desks that hate surprises. A halted venue during NFP once left a stubborn, lopsided book on his watch; since then, he treats kill-switches as first-class features. He is the person colleagues call when a cancel-replace storm starts—he found the idempotency bug none of us saw. Off the desk, he times his espresso shots like a latency test.
