$T-REX 2X Long MSTR Daily Target ETF(MSTU.US)The 3.5 put was exercised, but it was within the plan. The original intention was to build positions in batches. There are still two days to see if the 3 put will also be exercised. The 4.5 call premium is a solid income. After all the operations, the floating loss is less than ten points. So if stepping on a mine is unavoidable, it depends on how to operate to minimize the cost and loss. It's impossible to hit the point of a big rise in every order. Next, it's still a double-selling strategy, and it's not a big problem to earn a thousand dollars.
