boll突破下轨买还是卖

Investors often use Bollinger Bands (BOLL) to help determine their buying and selling points in the stock market. The upper Bollinger Band represents a sell point when the price exceeds it, while the lower Bollinger Band represents a buy point when the price falls below it. Additionally, breaking above the mid Bollinger Band indicates a potential addition to one's position, while breaking below it may signal a reduction or exit. However, there is more to consider when applying BOLL in trading strategies.

1. The Simple Usage of BOLL Indicator

When the price breaks above the mid Bollinger Band during an uptrend, it suggests a buying opportunity. Conversely, when the price breaks below the mid Bollinger Band during a downtrend, it indicates a selling opportunity.

2. Beyond the Simple Rules

Contrary to the simple rules, the price does not always break above or below the upper or lower Bollinger Bands randomly. There are certain conditions that need to be met for a valid signal. For instance, breaking above the upper Bollinger Band must also have an overbought condition, while breaking below the lower Bollinger Band must have an oversold condition.

3. Specific Conditions for Selling

When the price falls below the lower Bollinger Band, it signifies an oversold condition and can be considered a sell signal. Investors can use this signal to consider selling their positions.

4. Expanded Usage of BOLL

Most investors only use BOLL with simplistic rules, such as buying when the price breaks above the upper Bollinger Band and selling when it breaks below the lower Bollinger Band. However, there are additional signals that can be utilized:

1. Buy signal when the price breaks above the mid Bollinger Band, indicating a shift from weak to strong trend.
2. Sell signal when the price breaks below the mid Bollinger Band, indicating a shift from strong to weak trend.

5. Utilizing Quantitative Trading Software

Quantitative trading software, such as Jellyfish Quant, can automate the BOLL trading strategy by setting up conditions for automatic selling when the price breaks above the upper Bollinger Band and automatic buying when it breaks below the lower Bollinger Band. This software is beginner-friendly and provides preset BOLL templates that can be easily applied. The following steps demonstrate how to utilize the software:

By following these steps, investors can effectively automate their BOLL trading strategy and take advantage of the opportunities presented by the market.
