What did you post, and what happens to it if the move is rude?
Borrowed buying power, borrowed patience
Best AI Margin Trader
Margin is a loan from a mechanism that does not love you. Read the mechanism.
Context, not a slogan
Margin is the polite word people use when they mean borrowed notional. In traditional shops it comes with a broker and a margin call phone tree. In venue-native shops it comes with a maintenance ratio and a liquidation engine. OpenFidex will not pretend those are the same customer-service experience.
If the ticket borrows, this page applies. The leverage URL is the dial. This one is the relationship: you posted something, you can lose more than a cash debit you planned, and the AI does not get to “optimize your borrowing” like a cheerful loan officer.
A practical sequence
Use this as a checklist. None of it is a trading recommendation.
Find maintenance, not just initial
Initial is the sales pitch. Maintenance is the trapdoor.
Forbid the model from talking you into “using idle buying power”
Idle is often the only reason you are still solvent.
Plan the reduce before the call you will not receive
There may be no phone call. There may be only a smaller number.
Controls that matter for this style
No house credit department
We are not extending you a friendly line. A venue mechanism might be. Know which.
Cross vs isolated is a decision
If you do not know which you are in, you are in a horror movie. Check.
Leverage is the dial
This page is the borrowing relationship. Read both if you use either.
AI tone watch
If a sentence sounds like “put that cash to work,” close the card. That is lender energy.
Questions this page actually answers
Can I get a margin call email from OpenFidex?
Do not rely on us as your risk ops desk. Alerts may exist. Mechanisms will not wait for your inbox.
Is isolated margin always safer?
It can contain a blast. It can also liquidate a single idea faster. Safer is not a sticker.
Does AI manage collateral ratios?
It may comment. It does not get a standing right to reshuffle your life.
Why is this separate from perpetuals?
Perps are an instrument family. Margin is a financing relationship that can show up on more than one family.
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.
