English version： The first thing I did this week was not look for a new trade. I closed the straddle I had put on Nvidia last week. The table below summarizes the positions before I flattened the trade. The contrast was striking. The NVDA 227.5 call cost 4.39 and had fallen to 0.24, a loss of 94.53%. The put at the same strike and expiration cost 3.97 and had risen to 13.63, a gain of 243.61%. One leg was almost worthless, while the other had nearly tripled. Together they left the account with a profit of $2,530.50. That is the point of a straddle: you are betting on a large move, not on direction. Once the volatility has been realized, you should not overstay the trade. $纳斯达克(.IXIC)$
