BBI is also known as the long and short index, which is the bull-bear line. Simply put, when the K-line stands at the top and the trend is upward, it means that the bullish trend can hold more shares. On the contrary, when the K line falls below this line, it will turn into a short trend and should wait and see. Of course, in the complex and changeable stock market, it is not entirely dependent on a single index, and the judgment accuracy of multi-index resonance will be higher. Ok, now let's talk about how to set the BBI line. (Take Oriental Fortune Software as an example, and the others are similar. )

1. First open a stock, switch to the K-line chart, and click Do More in the indicator bar.

2. Click to select more indicators.

3. Select long and short BBI indicators and confirm them.

4, the final effect.
