Data and execution
Written in Rust 🦀
Architect Exchange (AX) is the first centralized and regulated exchange for perpetual futures on traditional underlying assets. Operated by Architect Bermuda Ltd and licensed by the Bermuda Monetary Authority, it brings the crypto-style perpetual contract to equities, foreign exchange, metals, energy, and interest rates. Contracts never expire, so there is no roll and no calendar spread to manage, and a funding rate keeps each contract aligned with its underlying index. Every market trades around the clock, seven days a week, which means gold, the 10-year Treasury, and Nvidia all keep pricing through the nights and weekends when their underlying markets are shut.
NautilusTrader integrates with AX through nautilus-architect-ax, a platform adapter written in Rust with Python bindings, providing both data and execution clients. It streams order books, quotes, trades, bars, mark prices, and funding rates, and submits orders over a WebSocket authenticated with a bearer session token obtained from an API key and secret. Every AX market loads as a single asset-class agnostic PerpetualContract, so the same strategy code reaches an equity, a currency, and a metal without special-casing any of them.
Asset classes
AX lists one product type, the perpetual future, across traditional asset classes that normally trade as dated contracts.

This is the full production listing at the time of writing. AX adds markets as it grows, and the adapter discovers the live instrument set at startup, refreshing it hourly, so new listings appear without a code change. The sandbox environment lists a slightly different set for testing.
Capabilities
Regulated venue
Operated by Architect Bermuda Ltd and licensed by the Bermuda Monetary Authority, AX clears perpetual contracts centrally rather than matching them on-chain.
Traded 24/7
Markets run seven days a week, pausing one hour daily for settlement and risk checks. Equities, metals, and rates keep trading through nights and weekends, when their underlying markets are closed.
Perpetual, so no roll
Contracts never expire, so there is no quarterly roll and no calendar spread to manage. A funding rate keeps the contract aligned with the underlying index.
Data and execution
One adapter covers both market data and order execution, with order, fill, and position reconciliation against the venue.
Bearer token sessions
An API key and secret exchange for a session token that authenticates every REST and WebSocket request, carried in the connection headers and reused across reconnects.
Sandbox and production
Select the environment with one config enum. Sandbox runs on simulated funds and is the default, so live trading is always a deliberate choice.
Data feeds
Each AX feed maps to a native NautilusTrader data type.

OrderBookDeltasAggregated price levels, delivered as a snapshot per message.
Order book (L3)
OrderBookDeltasIndividual order quantities resting at each price level. AX publishes no venue order IDs, so each message is a full snapshot rather than per-order tracking.
Quotes
QuoteTickBest bid and offer from the L1 book subscription; real-time only, as AX serves no quote history.
Trades
TradeTickLive trade prints from a trade-only WebSocket subscription.
Bars
BarOHLCV candles from 1 second to 1 day, carrying total volume without a buy and sell breakdown.
Mark price
MarkPriceUpdateContract mark price from the L1 ticker subscription.
Funding rate
FundingRateUpdateSettled funding polled over HTTP every 15 minutes by default, emitted when the rate changes.
Instruments
PerpetualContractEvery AX market loads as one asset-class agnostic type, with the asset class inferred from the underlying.
Status
InstrumentStatusOpen, halted, and closed transitions from the L1 ticker subscription.
Order types
AX triggers only to limit orders, so the conditional range is narrower than a crypto venue. Market orders are synthesized from the venue preview endpoint.
Type
Supported
Notes
Supported
AX has no native market order; the adapter prices one from the venue preview endpoint and submits an aggressive IOC limit order.
Supported
Native venue trigger; once the trigger price is breached, AX places the limit order.
Time in force
GTC, DAY, and IOC reach the venue natively. AX has no good-till-date or fill-or-kill, and recommends GTC over DAY.
Type
Supported
Notes
Supported
Immediate-or-cancel. AX reports an unfilled immediate order as an expiry, which the adapter maps to OrderCanceled.
Execution features
The execution instructions and account operations traders rely on.
Post-only
Maker-only limit orders, rejected by the venue if they would take liquidity.
Atomic replace
Amend a resting order in one call. AX cancels the original and creates the replacement itself, returning a new venue order ID.
Market order pricing
The adapter reads the take-through price from the venue preview endpoint before submitting, so a market order crosses the book at a known price.
Cancel on disconnect
Have the exchange cancel every open order if the orders WebSocket drops, so a network failure cannot leave orders working unattended.
Cancel all
Pull every open order for an instrument in a single request, with the resulting cancel events generated locally.
Reconciliation
Order, fill, and position state is rebuilt from the venue on startup, with fills reconciled over the most recent seven days.
Data and execution clients
Data client
Market data WebSocket with HTTP backfill
Feeds: order books, quotes, trades, bars, mark prices, funding rates, and instrument status.
Subscriptions: one active stream per symbol, with the adapter selecting the smallest AX level that covers every active Nautilus subscription.
Instruments: the live catalog loads at startup and refreshes hourly, so new AX listings appear without a restart.
Execution client
Orders WebSocket and a separate orders REST base URL
Orders: market, limit, and stop-limit entries, atomic replace, single and cancel-all, plus optional cancel-on-disconnect.
Account: order, fill, and position updates drive reconciliation, with accurate fees read back from the REST fills endpoint.
Safety: fractional quantities are denied locally, and sandbox is the default environment.

Considerations
AX is available to institutions in eligible jurisdictions, with a waitlist for individual traders; the sandbox environment is open for development against simulated funds.
Sandbox is the default environment; live trading with real funds requires setting the environment to PRODUCTION explicitly.
Instrument IDs append the venue to the AX symbol: NVDA-PERP.AX, EURUSD-PERP.AX, XAU-PERP.AX.
Every market loads as a PerpetualContract, with the asset class inferred from the underlying, so one instrument type covers equities, FX, metals, energy, rates, and compute.
Quantities are whole contracts, and fractional quantities are rejected before reaching the venue; the minimum order size varies per market, from 1 contract on equities to 10,000 on the smallest-tick FX pairs.
Time in force is GTC, DAY, or IOC; AX has no native GTD or FOK, and deprecates DAY in favor of GTC.
Order modification is an atomic replace, so the venue returns a new order ID rather than amending in place.
Batch cancel is not supported, so the adapter cancels orders individually.
Streaming fills carry no fee data and report zero commission; reconciliation reads accurate fees from the REST fills endpoint.
Reconciliation snapshots are built from open orders, so filled and canceled orders are not included; a single-order query works for any state.
Funding rates are polled over HTTP rather than streamed, every 15 minutes by default.
Order commands are never retried automatically, so a submit or cancel is sent exactly once.
