# Trading By opening a position, the trader borrows liquidity from the pool which decreases available pool reserves pro rata. After opening the position, the protocol swaps through reduced reserve pool, converting the borrowed Y tokens into additional X tokens, thereby increasing the trader's desired leverage. The trader then sends the initial margin in X tokens to the pool to overcollateralize the position, with the majority of the leverage provided by the pool's liquidity providers viathe borrowed reserves. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
