Near the strong support level 2230,Market index:Re-offer on the same day:
So as long as the stock price in your hand is not lower than the third line, don't sell it. Basically, after a bull market, you can never sell it. If you can't resist the temptation, buy and sell. That's hard to say.Near the pressure level 3450;
Science and technology-new quality generation, new energy, military industry, special evaluation, big finance, medicine and medical care, should be good.If you open lower, choose the opportunity to be bold and low-sucking, and after pulling up, throw it high to make a positive T.If it is high, throw away the part that was sucked low the day before, and wait for the opportunity to step back and suck in at a low level.
