Since I started tracking options, my biggest takeaway isn't "being able to calculate," but rather a more stable mindset: it turns out that time value really does eat away at you little by little. Buyers are betting on possibilities, and if the market stays still, they just wait to be worn down; sellers collect the wear-and-tear fee, but when a sudden move happens (especially during phases like unlocking or pledge unlocking where selling pressure anxiety is repeatedly mentioned), it's easy to lose all the gains made before. To put it simply: buyers fear dragging, sellers fear jumping. Now I don't get too caught up in ups and downs when watching the market; instead, I care more about "whether the market will give you opportunities during this period." If there's no opportunity, don't force it—just leave it at that.
