Funding vs trading · two different sides

Bitfinex margin funding bot vs margin trading bot

They share the same marketplace but do opposite jobs. Margin traders borrow capital to take leveraged price exposure. Funding providers lend that capital and earn interest without opening a trade. Stratum only automates the lender side.

Educational content, not financial advice. Leverage limits, fees, and eligible pairs are set by Bitfinex and change — verify current numbers on bitfinex.com before trading. Margin trading can lose more than your initial margin.

Stratum lends funds; it never trades your principal

A Stratum strategy can place, cancel and reconcile Bitfinex funding offers. It cannot open spot or margin trades, transfer funds, or withdraw from the exchange. Keys with trading or withdrawal permission are rejected when connected.

That boundary removes leveraged trading behavior from the product, but it does not remove Bitfinex platform risk, rate risk, idle-capital risk or the market value risk of lending a volatile asset such as BTC.

Margin trading & funding FAQ

Who pays the Flash Return Rate (FRR)?

Margin traders who borrow at the floating rate. The FRR is an index of recent funding activity; loans taken “at FRR” track it while open. Lenders on the other side receive it (minus the 15% fee). The same number is one side’s cost and the other side’s yield.

Is margin funding safer than margin trading?

It carries no price or liquidation exposure on your own position — the borrower’s collateral backs your loan, and liquidations exist to repay lenders. What remains is rate risk, idle-capital risk, and exchange/platform risk. “No price exposure” is not “no risk”: your capital lives on Bitfinex either way.

How do I take the lending side?

Move funds to your Bitfinex funding wallet and place funding offers — manually, via auto-renew, or through a bot over the API with a withdraw-disabled key. Rate and tenor choice is what separates lazy FRR returns from actively priced ones; that pricing problem is what Stratum’s backtested strategies automate.
