Auto take profit

A buy fill places the closing sell for you, at an offset you choose. Try it on the simulator, arm it on testnet, then decide.

This places real orders on your account. Keys are held in this tab's memory only — never written to storage, never sent anywhere except signed requests to the venue. Close the tab and they are gone, along with the bot: the dead-man's switch is what cancels your resting orders if this page stops talking to the exchange.

🔑 Rotate your key after every session

Revoke and re-issue your Orderly key when you finish here. A key that only existed for one session can only ever be misused for that session. Treat every key you paste into any website — including this one — as spent.
This is a community-built page, not FastX. Nobody has audited it but the person who wrote it. Read the source if that matters to you, and it should.
An Orderly key is scoped read,trading and cannot withdraw your funds — but it can trade them away. "Can't withdraw" is not "can't lose".
Never paste a wallet seed phrase or private key here. Nothing on this site ever needs one. If any page asks you for it, close the tab — it is not this site.
Start on testnet. Move to mainnet only after you have watched a closing order appear and confirmed it on the venue.
Orders placed are yours. This is unofficial software with no warranty, no support and no recourse if it misbehaves.

2 · I understand this places real orders on my account

⚠️ There is no dead-man's switch. The venue does not offer one to public accounts, so if this tab closes, any resting order stays live on the exchange.

What protects you instead: every order this bot places is reduce-only, so a stale one can only close a position you already hold — it can never open a new one. On close it also makes a best-effort cancel, though a closing tab cannot guarantee the request lands. Keep the tab open while it runs, and press Kill & cancel all when you finish.

Not verified.

Both directions are handled: a buy fill closes with a sell above it, a sell fill closes with a buy below it. Restrict it with the sides control if you only want one.
Each fill is acted on once — the closing order carries a client id derived from the fill id, so a retry cannot double up.
There is no venue-side dead-man's switch on public accounts, so resting orders survive this tab. Reduce-only is what keeps a stale order harmless.
The engine halts on repeated errors, on the session order cap, or when the free session runs out — it never quietly degrades.

Before you arm this on mainnet

A scoped key, not your exchange password. Orderly keys are delegated by an EIP-712 signature with scope read,trading and an expiry of up to a year, and can be revoked. They cannot withdraw — but a stolen trading key can still wreck an account through deliberate bad fills.
Keys stay non-extractable. The browser can generate an Ed25519 key that signs but can never be read back out as a string, stored in IndexedDB. A cross-site scripting bug could use it while the tab is open; it could not steal it.
A dead-man's switch. The tab is the bot. Close the laptop and nothing is watching your resting orders, so live mode must arm cancel_all_after and re-arm it on a heartbeat.
Testnet first. The venue has a full testnet on chain 421614 with the FastX broker enabled. Live money only after the engine has been proven there.
Your explicit arming. Live execution stays off behind a deliberate, per-session action — never a saved setting.
Prove it on testnet first. Run a real buy on testnet, watch the closing order appear in the log, then check it on the venue. Only move to mainnet once you have seen that happen.
