Pool Depth & Slippage Curve

A single quote tells you what one trade costs; this shows the whole curve. Price impact is calculated across nine trade sizes expressed as a share of reserves rather than absolute units, which makes the shape comparable between a small pool and a large one. It then solves the question people actually have — the largest trade that stays under half a percent, one percent, two or five — by binary search against the constant-product curve. It shows the absolute amount given up beside each percentage, because that is the figure which climbs fastest: doubling a trade roughly triples what it costs, since the size is multiplied by a percentage that is itself rising. Seeing that laid out is what stops a position being opened in one transaction when it should be split. The 0.3% fee is included throughout.
