Aqua drops two position shapes depending on what you're farming:

Straight = tight range, active only when price sits in your band. Built for volatile pairs where you want max capital efficiency in a specific zone.

Curved = smooth liquidity spread across prices. Perfect for stable/pegged pairs that don't swing hard—think stables or wrapped assets.

Pick your shape based on the pair's behavior. Volatility = Straight. Stability = Curved. Simple.
