Write both legs before either signature
One leg is a directional bet you dressed up. Call it that and size it that way, or stop.
Free money is usually a queue or a bug
Best AI Trader for Arbitrage
If it still looks like free money in a web app, you are late, you are the inventory, or you cannot actually do both legs.
Context, not a slogan
Arbitrage is catnip for AI landing pages because it sounds like math instead of gambling. In practice, the remaining crumbs sit behind speed, inventory, and privileges this product does not pretend to have. OpenFidex is a human signing surface. That already tells you most of the story.
If you see a basis between two listed names, you still have to complete two tickets, two fees, two failure modes. The AI can point at a spread. It cannot teleport the second fill.
A practical sequence
Use this as a checklist. None of it is a trading recommendation.
Budget the slow leg
The one that does not fill is the one that turns arb into a souvenir.
Include fees until the edge looks insulting
If it only works in a frictionless cartoon, it does not work.
Have a kill for residual risk
Residual is the trade you actually have. Treat it like one.
Controls that matter for this style
No colocated arb engine
See fastest-execution. We already refused the fairy tale.
Bridges are not arb, they are horror
Do not let a “spread” talk you into a wrap you cannot explain.
Copy-trading an arb whale is comedy
You will get their leftover, not their queue position.
AI pointing at a spread is a headline
Headlines do not complete legs.
Questions this page actually answers
Do you have a one-click arb?
A one-click that spends two places is two privileges. We will not hide that as a convenience.
Is funding harvest arb?
It is a tactic with directional leftover. See perps. It is not a money printer.
Can AI find cross-venue arb?
Even if it mentions a number, you may not have both venues, both speeds, or both brains. Assume you do not.
Why host the URL?
To meet the searcher before a Telegram “arb bot” does.
Does OpenFidex hold my funds or place trades for me?
No. OpenFidex is a non-custodial software interface. A wallet is created in your browser, you keep the keys, and you cryptographically sign every order before it reaches a third-party venue such as Hyperliquid. The software does not take custody of assets and does not submit transactions unless you sign them.
