保证金到底怎么算?一手期货要多少钱

一、保证金 = 合约价值 × 比例

期货保证金 = 合约价格 × 交易单位 × 保证金比例。比如螺纹钢 3500 元/吨、每手 10 吨、比例 10%,一手保证金就是 3500×10×10% = 3500 元。

二、比例决定杠杆倍数

比例 10% 对应 10 倍杠杆,5% 对应 20 倍。比例越低杠杆越高,波动一个点对你的影响就越大,强平风险也越高。

三、交易所和期货公司两道比例

交易所定最低比例,期货公司通常在此基础上加几个点。行情剧烈时交易所会上调比例,你的可用资金会瞬间变紧。

四、留足可用资金

别把保证金打满。账户要留 缓冲资金应对浮亏,否则一个反向跳空就可能被强平。保守者用不到一半仓位更稳妥。
