Follow the wife, 3500 on the first line, if it breaks, buy back again directly, stop loss is the lowest price of that K line. I don't know how many times it will test the bottom, the only thing that can be confirmed is that the backtest adjustment will be completed before the end of this month, and then there will be a breakout market, the market can last from 1 to 3 months. Missing it means wasting half of the bull market and the counterfeit market.
