How do you validate a strategy before it goes live?

Each strategy runs a walk-forward process with train/test splits that mimic live conditions. We check parameter stability, realized volatility regimes, and out-of-sample drawdown. A breach of the drawdown budget triggers a cooldown and blocks routing until variance normalizes.

Which market microstructure features do strategies use?

Common inputs include order book imbalance, spread dynamics, queue position estimates, and short-term realized volatility. For liquidity provision, we also monitor maker/taker fee schedules and expected adverse selection probability.

Can I set exposure caps per instrument or strategy?

Yes. You can define per-instrument and per-strategy caps, time-based throttles, and kill-switch conditions. All checks are enforced pre-trade and recorded with deterministic reason codes in the audit log.

Do you guarantee performance or profits?

No. Markets carry risk and results vary by venue, liquidity, and model fit. The platform focuses on auditable execution, risk guardrails, and transparent reporting; it does not provide investment advice or profit guarantees.

What happens after I enable a strategy from the library?

We run a paper session first, then route small live slices with idempotent API calls and time-in-force settings. Routing adjusts based on measured slippage and venue health. You receive attribution that separates model edge from execution effects.

Clear rules, explicit exits, and risk budgets. Each card lists inputs and the intended market regime.

Enable a paper session

Momentum capture

Signals: breakout bands, regime filter, realized volatility bands
Hold time: minutes to hours; trailing stops and time-based exits
Inputs: order book imbalance, spread dynamics, ATR
Use when: directional trends with stable depth

Mean reversion

Signals: VWAP deviation, Keltner channel fades, liquidity sweeps
Hold time: seconds to minutes; fixed target with hedged stop
Inputs: microstructure noise, queue position estimate
Use when: range-bound sessions with tight spreads

Liquidity provision

Signals: fair value band, inventory skew, spread elasticity
Hold time: sub-minute; inventory controls and decay exits
Inputs: maker/taker fees, expected adverse selection
Use when: stable depth with predictable queue churn

Event-driven

Signals: scheduled releases, venue halts, depth shocks
Hold time: seconds; throttle and circuit breaker heavy
Inputs: burst detection, idempotent routing, halt map
Use when: macro prints or exchange-specific updates

Sample playbooks with clear rules

Each strategy below shows the trigger, exits, and risk controls. All rules are visible in the audit log with timestamps and computed values.

HX-MOM-4H (trend capture)

Entry on channel break with a regime filter that checks realized volatility and spread elasticity. Exit via trailing stop and 4-hour max hold. Risk budget caps exposure at 1.2× average slice size; cooldown after two consecutive adverse exits.

Inputs: OBI, ATR, depth at top-of-book
Typical markets: BTC/ETH perpetuals

HX-VWAP-FADER (reversion)

Entry when price deviates beyond 1.2× Keltner from rolling VWAP with a liquidity check. Time-based exit or target at VWAP re-touch. Inventory and throttle rules prevent over-trading in noisy sessions.

Inputs: VWAP gap, microstructure noise index
Typical markets: major FX pairs, liquid alts

HX-MAKER-QUEUE (LP)

Quotes around fair value with queue-aware sizing and inventory skew. Circuit breaker pauses quoting on depth collapse or venue health warnings. Fees and adverse selection estimates decide maker vs taker flips.

Inputs: fair value band, queue churn, fee schedule
Typical markets: deep books with stable churn

Methodology and guardrails

Walk-forward validation checks parameter stability and regime sensitivity before capital is risked. We track realized slippage, dwell time, and cancel-replace storms. When distributions turn lopsided, allocation shrinks automatically. Circuit breakers contain venue outages without cascading retries.

Pre-trade checks: exposure caps, instrument limits, and kill-switch hooks
Execution: idempotent API calls, time-in-force, venue health scoring
Attribution: edge vs execution separated in PnL and audit logs

Checklist before enabling a model

Confirm walk-forward stability across three recent regimes
Review drawdown budget and cooldown conditions
Validate venue routing rules against current fee schedules
Set time-of-day throttles for known depth changes
Read the latest change-logs for target venues

This checklist reduces brittle assumptions and keeps activation decisions grounded in current market structure.

(Head of Execution, 11 years in FX/crypto routing)

Evan has spent the last eleven years building routing logic for desks that hate surprises. A halted venue during NFP taught him to wire circuit breakers before pretty dashboards. He is the person colleagues call when cancel-replace storms start; he once traced an idempotency bug that showed only on a Thursday open. Off-desk, he times espresso shots like a latency test.
