1. 流动性计算公式

假设当前价格为$P{c}$，用户提供提供流动性的价格区间为$[P{a},P_{b}]$

$ \LARGE L = \begin {cases} {Δx} \over {1 \over {\sqrt{P{a}}}} - {1 \over {\sqrt{P{b}}}} &, \text P{c} < P{a} \ {Δy} \over {\sqrt{P{b}} - \sqrt{P{a}}} &, \text P{c} > P{b}\ {{Δx} \over {1 \over {\sqrt{P{c}}}} - {1 \over {\sqrt{P{b}}}}} = {{Δy} \over {\sqrt{P{c}} - \sqrt{P{a}}}} &, \text P{c} \in [P{a},P_{b}] \ \end {cases} $
