Downside-first arbitrage infrastructure

The spread is visible.
The profit is engineered.

Arbiter sizes against real depth, prices every known cost, tests the downside, reserves inventory, and revalidates the edge before protected orders can move capital.

Value accuracy

A spread only matters after every cost survives.

The engine walks both books, evaluates multiple sizes, models venue-specific fees, and prices execution uncertainty twice: an expected case and a stricter doubled-reserve case.

01

Executable size

Searches several notionals and depth fractions instead of using a fixed quantity.

02

Known costs

Venue fees, price impact, inventory, latency, volatility, and failure reserves.

03

Protected downside

Dynamic reserves are doubled. Negative worst-case profit is rejected.

04

Final truth

Books, balances, and edge decay are checked again immediately before orders.

Execution engine

Seven gates between signal and capital.

Strategy logic cannot bypass risk logic. Each transition is timestamped, idempotent, and available for audit.

01

Normalize

Canonical markets, venue precision, fresh local books.

02

Size

Choose the conservative profit-maximizing quantity.

03

Risk

Reject stale, costly, imbalanced, or low-confidence routes.

04

Reserve

Atomically hold quote and base inventory.

05

Execute

Submit protected IOC legs with idempotency.

06

Recover

Hedge residual exposure and pause when unresolved.

07

Reconcile

Record venue fees and realized net PnL.

Seamless fund management

Inventory should move with intention, not panic.

Balance refresh, temporary reservations, target allocations, drift detection, and rebalancing plans share one auditable capital model.

USDT allocation

Binance42% / 40% target
Kraken31% / 30% target
OKX27% / 30% target

Atomic reservations

Capital cannot be double-spent by concurrent workers.

Drift intelligence

Rebalancing proposals distinguish fund, reduce, and hold actions.

No withdrawal keys

Connected venue credentials are read-and-trade only by policy.

Investor-grade infrastructure

Built to prove where value came from.

PostgreSQL records orders, fills, executions, reservations, ledgers, and audit evidence. ClickHouse preserves market and latency analytics. Redis protects the real-time path. MongoDB isolates encrypted secret envelopes and notifications.
