Roof escape skills of bollinger band
1, using the core principle of bollinger band escape: identify various technical characteristics before and after the stock price peaks, so as to seize the opportunity to sell in time.
At the end of the rebound, the bandwidth of the rapidly rising stock bollinger band has been too wide, and the stock price has rushed out of the bollinger band for two to three days. The deviation rate on the 6th is greater than 14, and the deviation rate on the 25th is greater than 20, so it can be sold.
2. When the stock price rises weakly, it is obviously suppressed by the middle and upper rails of the Bollinger Band. Although the stock price is higher or slightly higher than the previous high point, the phenomenon that Brin limit BB is lower than the previous high point can be sold.
3. When the stock price falls below the upper and middle rails of the Bollinger Band in a short time, it can be sold in a short time.
4. When the average of 5th and 10 is in the middle of the gauge, it is necessary to clear the position.
Bollinger band technique
The core principle of bargain hunting in sports bollinger bands is to pay attention to whether the stock price breaks through the middle and lower tracks of bollinger bands effectively, quickly and continuously.
Every round of stock market adjustment breeds a new round of rise. Only by actively selecting stocks in the adjusted market and buying them in time can we avoid chasing up and down when the stock market rises. The so-called "bull market makes money, bear market stocks" is a good time to bargain-hunting stocks when the general trend is weak.
Bottom-hunting often chooses the time when the stock price turns from weak to strong after long-term adjustment. The application of bollinger bands should pay attention to the following points:
We can't say that the stock price crossing the support line is a buying signal, but we should take the closing line of a stock crossing the bollinger band as a signal that we can initially pay attention to the stock.
After the primary election signal appears, the general stock price will be adjusted back. If the stock price retracement does not effectively penetrate the lower rail, and Brin takes the lower rail head up. At this time, it can be initially confirmed as a buy signal.
The final confirmation of the buy signal is mainly to observe whether the closing line can break through the middle track line and whether the trading volume can be moderately enlarged.
Pay attention to whether the width of the bollinger band is in a convergent state, which is also an important factor in signal confirmation.
For example, Amoi Electronics' liquidation line exceeded the lower rail of Bollinger Band, and then the stock pulled back to the lower rail without breaking, and finally broke through the middle rail. The bollinger band support line also shows obvious signs of turning head, and the upper and lower rails of the bollinger band also converge to the limit synchronously. Steady investors can wait until the volume is moderately enlarged before intervening. As shown above.
