一年前突发奇想，想出一个牛熊通吃的炒股大法。当时预测牛市underperform，熊市outperform。一年下来， 净空出尽2022-06-20 14:13:57

果然如此。

基本上就是 keep buying several OTM Put broken wing buttefly expiring at least 3 months away, targeting crashing 25%, at different times and defferent strike prices, then combine them as time progresses to form long put spread on top and short put spred on bottom. My principle is this: you must recieve recieve a credit for each trade. If no credit, then don't enter the trade. eg. now spy at about 370, you can start to buy 310/295/180 put butterfly expiring in Sept 16, 2022 or December 16, 2022 tomorrow.

Tomorrow is not a good time to long put spread

I don't anticipate market and don't pay for any trade.

谢谢分享。请问什么情况退出呢？

不退出。长持到expiration

只有在paper account 里 你才能拿到 credit 实际操作你要把两个腿分开做 还要猜对才行

谢谢回复。

做这种butterfly 还不如 做个简单的 poormans covered call or put

我从没设立 paper money account。Credit 立马进入账户的现金部分。
