Trade and swap

What the Trade page shows, and what long and short mean here.

The Trade page is a spot terminal on top of the perp market Aven reads.

Long and short#

Long buys aETH and short sells it, as a spot swap on the pool you pick. There is no leverage and nothing to liquidate: Aven reads the perp market, it never trades it.

Why your fee can be lower#

The gap term only applies to the side that closes the gap. If your trade goes the other way, you usually pay the base fee, which is below the plain pool's 0.30%.

The panel shows which terms fired before you sign, and the receipt links to the full proof.
