Execution
Live Crypto Trading
Most terminals ask you to trust them with your money. This one cannot touch it. Orders are composed in Arxion and signed by your own wallet, then go straight to the exchange — we take no custody, hold no key that can withdraw, and never see a password. What we add is what happens either side of the order: finding the move before the price shows it, and telling you honestly afterwards whether you were right.
What non-custodial actually means here
The phrase is used loosely enough to be worthless, so here is the specific version. Your funds sit in your own account on the exchange. Arxion cannot deposit, withdraw, move, freeze or reverse them, and cannot cancel a transaction once you have signed it.
To avoid asking you to sign every order by hand, a trading key is generated in your browser and you authorise it on the exchange. That key can place orders, cancel them, set leverage and move margin between your own balance and your own positions.
It cannot move money off the exchange — and that is not a promise about our conduct, it is a property of how the venue's signatures work. A withdrawal payload carries no account field, so the source of funds is whoever signed it. A signature made by the trading key could only ever withdraw from the trading key's own empty address, never from yours.
You revoke that authorisation yourself, in your own exchange settings, without asking us.
Stops that live on the exchange, not in your browser
A stop that only exists in a web page is not a stop. Close the tab, lose the connection, let the laptop sleep, and it is gone at the moment it is needed.
A stop placed through Arxion is a resting trigger order in the exchange's own book. It fires whether or not the tab is open, whether or not your machine is on, and whether or not our servers are running.
Measured, not asserted: on 27 August 2026 a stop on a RUNE short rested for 76 minutes and filled by itself, at a trigger the trader had set 21 seconds after entry. The order lifecycle on the venue reads open, then triggered, then filled — our infrastructure was not involved in any of the three.
What we charge, and why it costs more than trading direct
Arxion charges 0.05% of order value on entry. Three things about it that most interfaces leave you to discover.
It is added to the exchange's own fee rather than taken out of it. Trading through Arxion therefore costs more than trading on the exchange bare, and anybody who tells you otherwise about a builder fee is being imprecise.
It is charged on entry only. Closing a position is never charged by us.
And you approve a maximum rate with your own wallet signature before a single order can carry it. The exchange refuses anything asking for more than you approved, so the ceiling is enforced by the venue and not by our good behaviour.
The reason to pay it is not the execution — the exchange does that, and it would do it without us. It is the two ends: the detection that got you there and the audit that follows.
The trade is judged, not just executed
This is the part almost nobody does, and it is why the fee is defensible. Every fill lands in your journal automatically, collected server-side so that a stop firing at four in the morning with nothing of yours open still reaches your history.
From there it feeds Trading DNA, which grades the trader rather than the market, and the stop-loss efficiency study, which will tell you unwelcome things — that you exit winners early, for instance, with the number attached.
We apply the same standard to ourselves. The outcomes table grades our own detections against Bitcoin at 12, 24, 48 and 96 hours, and we publish the misses. A service that sells signals cannot afford to do that.
One position is one row
An exchange fills a single order across several price levels when the book is thin. A raw fill log shows that as several separate trades, and every statistic built on it then counts a trade the person never made.
It happened here and was fixed: one RUNE short, closed by a single order the matching engine walked across four levels, appeared as four losing trades. Win rate, trade count, streaks and the leaderboard were all counting it four times.
Arxion reassembles fills into positions, flat to flat, so a win rate counts trades a human would recognise. The raw execution log is kept and remains visible, because a close that happened in four pieces is the truth and is worth being able to look at.
What this is not
Arxion is not a broker, a dealer, an exchange or a counterparty to any trade. We do not accept your order, transmit it, execute it or settle it — your wallet does, and the exchange does.
Nothing in the product is financial advice or a recommendation. Detection flags unusual activity that has already happened; it does not forecast a price.
Leveraged perpetuals can lose your entire deposit quickly. A stop becomes an order when triggered and in a fast market can fill far from its trigger. Only trade money you can afford to lose.
Trade from the chart without handing anyone your keys.
Practice book included — the same terminal, on a separate ledger.

Does Arxion hold my crypto?
No. Your funds stay in your own account on the exchange. Arxion cannot deposit, withdraw, move or freeze them, and the trading key it uses is cryptographically unable to withdraw — a withdrawal signature carries no account field, so that key could only ever withdraw from its own empty address.
Do my stop losses work if I close the browser?
Yes. A stop placed through Arxion rests as a trigger order in the exchange's own order book and fires without your browser, your machine or our servers. Observed on a live position on 27 August 2026: a stop rested 76 minutes and filled on its own.
What does Arxion charge for live trading?
0.05% of order value on entry, added to the exchange's own fee rather than shared out of it, and never charged when you close. You approve a maximum rate with your own wallet signature, and the exchange refuses any order asking for more than you approved.
Which exchange do orders go to?
Hyperliquid perpetuals today. The venue is named at the point of action in the terminal, because the account, the balance and the positions are yours on that exchange and are governed by its rules, not ours.
Do I need to give Arxion an API key or a password?
Neither. There is no field for a key or a password anywhere in the product, and no route that could accept one. You connect a wallet and authorise a browser-held trading key on the exchange, which you can revoke yourself at any time.
Can I practise before risking real money?
Yes. The same terminal runs a practice book with the same charts, tools and order types, kept on a separate ledger so practice results never mix into a real performance figure.
