When I woke up in the morning and looked at the market, I thought the strongest was rare. In the afternoon, I saw the change in rates and noticed ogn, but I didn't go to open a position!
Then in the afternoon, I checked the contract gainers list and found that ogn was indeed the strongest, with an increase of more than ten points since the first time I saw it!
I missed it. In this market, one needs to be more decisive!
