An upgraded version is planned for Opyn's new protocol, which is soon to be released. Over a day, its payoff is described as resembling a rainbow, with the largest return if the market does not move at all. Returns turn negative if the market moves too much up or down. ## Article Crab and the Pierian liquidity spring Today we look more deeply at the Crab strategy that is part of Opyn's Squeeth protocol and its upgraded iteration in Opyn's new soon-to-be-released protocol. Crab is an active strategy made from a short 2-perpetual (also known as Squeeth) and a long 1-perpetual. Crab is called Crab because it makes money when markets go sideways, like a Crab. The payoff for Crab over a day looks like a rainbow: it makes the largest return if the market does not move at all. Crab has negative returns if the market moves too much up or down.
