Go short, go short, go long, go long, use real money to practice your opinions, show delivery orders if you have the ability, don't talk, shout short sometimes, long sometimes, follow a rhythm every day, and integrate knowledge and action. In the long run, we look at the big pie, but with the current volume, don’t even think about the sudden surge. Go long on dips and short on rallies. We are firmly bullish on spot prices. Just play with small positions in contract options, just for fun
