I suspect this is a copy paste error, meaning two strategies 什麼是布林通道(Bollinger Band) 什麼是布林通道(Bollinger Band) are mixed together. From what I understood is this strategy does not have an EA (Expert Advisor). You simply plot the 什麼是布林通道(Bollinger Band) RS (14) and Bollinger Bands on your chart and look for divergences in RSI together with spikes outside the Bollinger Bands as 什麼是布林通道(Bollinger Band) 什麼是布林通道(Bollinger Band) described in "Rules for Buy / Sell Signal". Keep in mind that RSI can stay overbought for a longer period of time when the trend is strong. A one off divergence does not necessary mean a trend change. It is a good countertrend strategy for pullbacks. Always look at the higher timeframe.

Bollinger Band Trading Strategy
A Bollinger Band is a technical analysis tool defined by a set of trendlines plotted two standard deviations away from a simple moving average of a security’s price.
Bollinger Bands were developed and copyrighted by famous technical trader John Bollinger, designed to discover opportunities that give investors a higher probability of properly identifying when an asset is oversold or overbought.
Very well known in the trading community, Bollinger Bands contain all trading activity occurring between the two standard deviations of the expected norm, 什麼是布林通道(Bollinger Band) which is also known as the trend line.
Overall, Bollinger Bands make it easy for traders to buy low and sell 什麼是布林通道(Bollinger Band) high.
Bollinger Bands Indicator
The Bollinger Band is an excellent indicator for measuring market volatility. The bands sum up the price movement of a stock and provide relatively high and low boundaries.
The Bollinger Band indicator is based on a moving average, which 什麼是布林通道(Bollinger Band) defines the ‘trend’ on the basis of the time frame that you choose to view.
How to Calculate Bollinger Bands using Formula?
The Bollinger Band formula consists of the Upper and Lower band, which make use of the Moving Average (ma). Before we move on to the formula for the bands, we have to calculate the ma.
The formula for Moving Average is:
Moving Average(ma) = SimpleMovingAverage(close, period)
The Upper Bollinger Band is the sum of the Moving Average and the standard deviations. The formula is:
Upper Band= ma+ devfactor * StandardDeviation(data, period)
The Lower Bollinger Band is the difference between the 什麼是布林通道(Bollinger Band) Moving Average and the standard deviations. The formula is:
Lower band= ma – devfactor * StandardDeviation(data, period)
Why use Bollinger Bands 什麼是布林通道(Bollinger Band) Trading Strategy?
To measure market volatility, the standard deviation formula is used. It showcases how the stock price may vary from 什麼是布林通道(Bollinger Band) its original value.
Bollinger Bands measure this market volatility and then adjust themselves to the market conditions accordingly. This makes the Bollinger Bands Trading Strategy so handy for traders.
Through this trading strategy, traders can find most of the price data required 什麼是布林通道(Bollinger Band) between the two bands, ensuring the correct market entry and exit.
How to use Bollinger Bands Trading Strategy?
There are three lines that compose Bollinger Bands: A simple moving average (middle band) and an upper and lower band.
The upper and lower bands 什麼是布林通道(Bollinger Band) are typically 2 standard deviations +/- from a 20-day simple moving average but can be modified.
Prices have a tendency to bounce within the bands’ envelope, touching one band then moving to the other band. You can use these swings to help 什麼是布林通道(Bollinger Band) 什麼是布林通道(Bollinger Band) identify potential profit targets. For example, if a price bounces off the lower band and then crosses above the moving average, the upper band then becomes the profit target.
Price can exceed or hug a band envelope for prolonged periods during strong trends. A strong trend continuation can be expected when the price moves out of the bands.
- When the price touches the lower bands, it signifies that the price is oversold and has a tendency to bounce back.
- When n the prices stay above the upper band for some time, it signifies that the uptrend is extremely strong
- When the price touches the upper bands, it signifies that the price is overbought and has a tendency to return back.
