【理财类-01-05】20260715ZFB积存金“差价”收益计算(Python)回本平衡测算&目标收益定价&持仓损益结算https://mp.csdn.net/mp_blog/creation/editor/162901013

等了一天,单笔买入的积存金没有达到回本金额,所以积存金快进快出赚差价只是理想状态,又一次套住了。

但是我看到之前套住了两笔积存金的均价从1027元降低到902元。

所以我想做一个“多笔买入、一次卖出”的回本价预估

一、“多笔买入一次卖出”的保本盈亏平衡计算器

感悟:

积存金只能做地埋高卖(做多)的差价,所以风险极大。

四、降低平均价格,如何补仓

等了两天积存金价格越来越低(在876-878之间徘徊,),但我没有钱补仓了。我想计算一下,如果把平均价压到878元,还需要补多少克、多少钱?

平均价压到878,但是还要扣掉3.62元手续费,所以压价到874(这个预估,没有测试过一定能再向下降低价格)

要再买20万,220克。

但是我觉得不太对,没有输入补仓的买入价

他说买入补仓价是870元*109克,才能让成本降到874元,也就是878补仓的话,没法把平均价压到874。

另外写一个EXCEL测试,无论补仓价位买多少克(10000000000G),平均价只会无限接近与补仓买入价(878元)

所以只能等伦敦金的波动,起到它会突然拉涨。

小红书说支付宝的积存金的预约单经常没法成交,还是要手动挂单才能生效。不过我设置的预约单成交了(已执行),不过不是第一时间成交(要排队等候成交),要金价来回摆动到这个价位几次才能成交。预约的好处就是能整数买入卖出。
