永续合约（perps）是一种追踪资产价格的合约，你不需要持有资产本身。你对价格的走向下注。走势如你所料，你就盈利。走势与你相反，你就亏损。

与传统期货不同，永续合约没有到期日，所以只要你的保证金撑得住，仓位想持多久就持多久。

在 fomo 上，如果你认为价格会上涨，可以做多；认为会下跌，可以做空。这是与现货交易的主要区别，现货只有在代币价格上涨时才能盈利。

你还可以在永续合约上使用杠杆，用较少的 USDC 控制更大的仓位。杠杆在两个方向上都起作用，会以同样的倍数放大你的盈利和亏损。

永续合约在 iOS 和 Android 的 fomo App 以及 fomo.family 网页版上都可以交易，两边使用同一个账户。大多数市场是加密货币，也有一些追踪股票、大宗商品和指数。

fomo 上的每一个永续合约仓位都由 USDC 支撑，而你在 fomo 上有两个独立的现金池。你的代币现金余额持有 Solana 上的 USDC，用于现货交易、充值和提现。你的永续合约现金余额持有专门用于永续合约的 USDC。

要交易永续合约，你需要把 USDC 从代币现金余额转入永续合约现金余额，它就成为你仓位背后的保证金。

开始之前，你应该了解其中真实存在的风险。杠杆越高，越小的反向波动就能让你的保证金归零，而一旦仓位被强平，这些资金就永远没有了。

持有仓位还会随着时间通过资金费支付产生成本，资金费率那篇文章有详细说明。永续合约并不适合所有人，它的风险远高于通过现货持有代币。
