Multi-broker
We are not asking you to move house. We are asking for the bridge keys — if that bridge exists. Four adapters already in code. Then only venues with a retail API the model can speak. The rest is not «on the map»: it is off it.
The course stays yours
Marks belong to their owners: they name the venues, they do not imply a partnership. Gold = adapter already in code. The slide shows only retail APIs that fit. Fineco, DEGIRO, Robinhood and the rest without an official trading API stay off it.
A logo on a landing page is easy. Landing a covered order there is another craft. That is why the slide names the venues that can be wired — and the code says who is actually wired.
Putting Interactive Brokers, Directa or Schwab on a page is an afternoon of CSS. Getting a stop-attached entry there is a contract, a payload, a session clock, a way to read the order list. Alpaca wants brackets and OTO, a helmsman_… client id. Tradier wants OTOCO in a form payload, a hyphenated tag, a bearer token. Idempotency, a closed cash session, how a stop is reconciled: all different.
Paste Alpaca onto Tradier and you open naked while calling the mess «multi-broker». Helmsman does not pretend the world is one API. Every adapter carries its own engagement card: how you enter, how you must not, what happens when the session is closed. You stay a client of whoever gives you the book. We lengthen the bridge, venue by venue — and only if the venue exposes an API the model can respect.
In code today: Alpaca (paper), Tradier (sandbox), IG (demo) and Interactive Brokers (mock-tested, live pending), plus PaperSim locally to prove the rules with the network off. Saxo, OANDA, lemon.markets: next. Then Schwab, cTrader, Tiger, Tradovate, Questrade, MetaApi and the other APIs that fit. Directa, eToro, Trading 212, moomoo: integrable, with friction. Fineco, DEGIRO, Robinhood, Fidelity, Trade Republic, Plus500: no official retail trading API — we will not fake them with a sticker.
The marks you see belong to their owners. They name the venues; they do not sell a partnership that does not exist. Gold on the tile = bridge already in code. Grey = to build. Amber = with friction. No fake «certified integration».
The same human yes. The same cover. Different payloads. If the bridge does not respect the venue, it is not a bridge: it is a bug with a logo.
ADAPTER · PAPER
First live bridge. Brackets and OTO, a traceable client id. The adapter is paper: a seat, when there is one, is for clients. This is where we learned that «covered» is an order class, not a promise in chat.
ADAPTER · SANDBOX
Second real broker. OTOCO in a form payload, a sanitised tag, sandbox. It proved the thesis: copy Alpaca here and you open naked. So we do not copy it.
ADAPTER · DEMO
Third bridge. The adapter is done: it runs in demo. Live is a key, not another craft. Same thesis as Tradier: its own CFDs and sessions, no Alpaca paste.
ADAPTER · MOCK
Fourth bridge. Mock-tested: the gateway is there, go-live is not. IBKR is not brochure REST: it is TWS/Gateway on the machine. That is why live stays pending until covers and session are honest.
PaperSim stays the bench: no keys, no network, so the rules can fire before a venue is touched. It is not a broker. It is the workshop.
TIER A
Gold = a bridge already written. Paper, sandbox, demo or mock: a covered order has a grammar, not a logo.
Live adapter: paper environment, bracket and OTO, human confirm, helmsman client id.
Second real adapter: OTOCO, tags, sandbox. Not Alpaca with a sticker.
Adapter done. Demo already in code; live is a key, not another craft.
Adapter done, mock-tested. Live is pending: the gateway is there, go-live is not.
TIER B
REST APIs, sandboxes, brackets or OCO. Saxo, OANDA, lemon.markets: next. cTrader and MetaApi are one adapter, many venues. The others meet the same bar: contract and API, then the bridge.
OpenAPI REST, $100k SIM, related orders. The model fits: this is the next one to build.
v20 REST, Practice account, native covers. Fits like IG: FX with an honest grammar.
Developer-first REST, free paper, stocks and ETFs. An EU broker that speaks like an adapter, not a terminal.
One Open API, many venues: Pepperstone, IC Markets, FxPro. One adapter, the book stays with the broker you already have.
Open API, paper account. REST that fits, still to build.
REST for futures. The US tape that is not equity: the same bar, a different grammar.
REST OAuth2, Canada. A retail API that fits. To build.
REST over MT4/MT5: one bridge, thousands of brokers. Not the venue — the pipe to whoever runs MetaTrader.
Trader API, OAuth2, sandbox, brackets. Fits. To build.
WebAPI REST, simulator, OCO/OSO. Fits. To build.
Open API, OAuth2, sandbox, brackets. Fits. To build.
OpenAPI REST, sandbox, native OTOCO. Fits. To build.
Legacy OAuth1 REST, sandbox, preview/place. Fits, with OAuth1 dust. To build.
TIER C
It can be done. It is not the same craft as Schwab. Directa and moomoo are a local gateway; Trading 212 is a beta; eToro is CFD/social.
Public API in beta, demo, market+limit+stop. Invest/ISA only. Integrable, with friction.
New public API: demo, market + SL/TP on the position. CFD/social model, like IG. Integrable, with friction.
A real dAPI, but local TCP sockets on Darwin — a machine gateway, not REST. Integrable, with friction.
Futu OpenAPI via the OpenD gateway on the machine — the same craft as IBKR, not browser REST. Integrable, with friction.
UNITED STATES
Three adapters already in code. Schwab, TradeStation, tastytrade, Webull, E*TRADE, Tradovate: public APIs, still to build. Fidelity and Robinhood stay off the slide.
EUROPE · ITALY
IG already has the demo adapter. Saxo and lemon.markets are next. Directa is in the friction queue (Darwin on the machine). Fineco is PSD2 only. DEGIRO has no official API.
GLOBAL · FX · FUTURES
OANDA fits like IG. cTrader is one API, many brokers (Pepperstone, IC Markets, FxPro). MetaApi opens MT4/MT5. Questrade is Canada. moomoo is OpenD on the machine: friction, like IBKR.
Helmsman does not reverse-engineer the browser and does not break ToS. If there is no official retail trading API, the name does not run on the marquee.
TIER D · INSTITUTIONAL ONLY
TIER E · NOT INTEGRABLE
On the pre-registration, name the broker you already use. It is not a pitch to open a new account. It is the queue: Saxo, OANDA, lemon.markets, Directa or IBKR tell us where to lengthen the bridge after the four already in code. If you trade from Fineco or DEGIRO, say so anyway: we know the bridge is not there.
Your yes stays the same. Only who receives the covered order changes — and only if that who exposes an API. That is the only invariant we are selling you.
We are in early access. Skills and adapters are moving fast: you can pre-register.
Pre-registerPass-through
Helmsman is middleware: it translates, vetoes, forwards. The LLM proposes. You confirm. The broker — on your account — is the final executor.
Not us
Claude or another third-party model can hallucinate, botch the numbers, invent a name. That call is not Helmsman.
This is us
Routing, rules, covers. If the stop is missing, if size moved, if you did not say yes — the pipe closes. We do not hold your book.
Final executor
Alpaca, Tradier, or the venue you connect. If an order exists, it exists on their book. Helmsman is not your intermediary and not your bank.
If the order exists, it exists on your account, after your yes. Helmsman is the pipe. Not the captain. Not the till.
