I suspect this is a copy paste error, meaning two strategies 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 RS (14) and Bollinger Bands on your chart and look for divergences in RSI together with spikes outside the Bollinger Bands as 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, 什麼是布林通道(Bollinger Band) designed to discover opportunities that give investors a higher probability of properly identifying when an asset is oversold or overbought.

Very 什麼是布林通道(Bollinger Band) well known in the trading community, Bollinger Bands contain all trading activity occurring between the two standard deviations of the expected norm, which is also known as the trend line.

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 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 什麼是布林通道(Bollinger Band) 什麼是布林通道(Bollinger Band) Average(ma) = SimpleMovingAverage(close, period)

The Upper Bollinger Band is the sum of the Moving Average and the standard 什麼是布林通道(Bollinger Band) 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 its original value.

Bollinger Bands measure this market volatility and then adjust themselves to the market conditions accordingly. This makes the 什麼是布林通道(Bollinger Band) 什麼是布林通道(Bollinger Band) Bollinger Bands Trading Strategy so handy for traders.

Through this trading strategy, traders can find most of the price data required between the two bands, ensuring the correct market entry and exit.

How to use Bollinger Bands Trading Strategy?

There are three 什麼是布林通道(Bollinger Band) lines that compose Bollinger Bands: A simple moving average (middle band) and an upper and lower band.

The upper and lower bands 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 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.

Bullish Scenario

  • When the price touches 什麼是布林通道(Bollinger Band) 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

Bearish Scenario

  • When the price touches the upper bands, it signifies that the price is overbought and has a tendency to return back.
  • When the 什麼是布林通道(Bollinger Band) prices stay below the lower band for some time, it signifies that the downtrend is extremely strong.

Building Bollinger Bands Strategy 什麼是布林通道(Bollinger Band) 什麼是布林通道(Bollinger Band) on Mudrex

You can create crypto strategies on Mudrex using simple ‘blocks’. You can connect multiple blocks and define conditions on those connections 什麼是布林通道(Bollinger Band) or ‘paths’ to create your strategy on Mudrex.

BUY: When the price goes below the lower band, it signifies that the price is oversold. When it 什麼是布林通道(Bollinger Band) starts recovering, then one should take a long position.

Buy when the price crosses up the lower band.
