Premium refers to the price of options. I bought it for 7 yuan, and now it's only 4 yuan. Did you lose some premium when you closed your position? This is the same as the stock. If you don't implement it when it expires, it will obviously make all your royalties zero, and you will really lose everything. But sometimes you lose more when you exercise your rights, so you should exercise your rights and analyze them in detail. Anyway, the most important thing is royalties.
