How to Use Bollinger Bands (볼린저 밴드 사용 방법)

 

Bollinger Bands are a technical indicator created by John Bollinger in the 1980s. They were created to form a quantified visual trading range that was adaptive to dynamic volatility expansion and contraction.

볼린저 밴드는 1980년대 존 볼린저가 만든 기술적 지표입니다. 그들은 동적 변동성 확장 및 수축에 적응할 수 있는 정량화된 시각적 거래 범위를 형성하기 위해 만들어졌습니다.

 

“Bollinger Bands are use a measure of central tendency as a base such as a moving average. They curves drawn in and around the price structure usually consisting of a moving average (the middle band), an upper band, and a lower band that answer the question as to whether prices are high or low on a relative basis. Bollinger Bands work best when the middle band is chosen to reflect the intermediate-term trend, so that trend information is combined with relative price level data.” – John Bollinger“

볼린저 밴드는 이동 평균과 같은 기준으로 중심 경향의 사용척도이다.그들은  일반적으로 가격이 상대적으로 높거나 낮은지 여부에 대한 질문에 답하는 이동 평균(중간 밴드), 상위 밴드 및 하위 밴드로 구성된 가격 구조 안팎에서 곡선을 그립니다. 볼린저 밴드는 중간 밴드가 중기 추세를 반영하도록 선택되어 추세 정보가 상대 가격 수준 데이터와 결합될 때 가장 잘 작동합니다." – 존 볼린저

 

Bollinger Bands are a technical trading tool that is universal to all markets and trading time frames. This indicator was designed to show if prices are high or low on a relative basis for the chart. It shows if price is high at the upper band or if price is low at the lower band. This information is valuable for both ranges and can show when a trend is about to emerge outside the bands. Volatility is based on the standard deviation, which changes as volatility increases and decreases. The bands automatically widen when volatility increases and contract when volatility decreases. It is a great addition to a traders parameters and is useful inside the context of a confluence of other technical indicators.

볼린저 밴드는 모든 시장과 거래 기간에 보편적인 기술 거래 도구입니다. 이 지표는 차트에 대한 상대적인 기준으로 가격이 높은지 낮은지를 보여주기 위해 고안되었습니다. 가격이 위쪽 밴드에서 높은지 낮은 밴드에서 가격이 낮은지 보여줍니다. 이 정보는 두 범위 모두에 유용하며 추세가 밴드를 벗어나려고 하는 시기를 보여줄 수 있습니다. 변동성은 변동성이 증가 및 감소함에 따라 변하는 표준 편차를 기반으로 합니다. 밴드는 변동성이 증가하면 자동으로 확대되고 변동성이 감소하면 축소됩니다. 이것은 트레이더 매개변수에 대한 훌륭한 추가이며 다른 기술 지표의 합류 맥락에서 유용합니다.

Bollinger Bands consist of a middle band with two outer bands. The middle band is a simple moving average that is usually set at 20 periods. A simple moving average is used because the standard deviation formula also uses a simple moving average. The look-back period for the standard deviation is the same as for the simple moving average. The outer bands are usually set 2 standard deviations above and below the middle band.

볼린저 밴드는 두 개의 외부 밴드가 있는 중간 밴드로 구성됩니다. 중간 밴드는 일반적으로 20주기로 설정되는 단순 이동 평균입니다. 표준편차 공식에서도 단순이동평균을 사용하기 때문에 단순이동평균을 사용합니다. 표준편차의 룩백 기간은 단순이동평균과 동일합니다. 외부 밴드는 일반적으로 중간 밴드 위와 아래에 2 표준 편차로 설정됩니다.

A move in price to the upper band shows strength, while a price move to the lower band shows weakness. During range bound markets price action will stay within the bounds of the bands. During strong up trends price will ride up the upper band pressing it higher, during strong downtrends the price will push against the lower band and force it lower. A break outside one end of the bands can be a parabolic trend signal in the direction of the breakout. In sideways markets price will revert back from the upper or lower band to the middle 20 period moving average after reaching the top of bottom band. If price is over the 20 period moving average it is signaling an uptrend if price is below the 20 period moving average it is signaling a downtrend.

상단 밴드로의 가격 이동은 강세를 나타내고 하단 밴드로의 가격 이동은 약세를 나타냅니다. 범위 경계 시장 동안 가격 행동은 대역 경계 내에 머물 것입니다. 강한 상승 추세 동안 가격은 상단 밴드를 상승시켜 더 높게 누르고, 강한 하락 추세 동안 가격은 하단 밴드를 밀어내서 더 낮추게 됩니다. 밴드의 한쪽 끝을 벗어난 브레이크는 브레이크 아웃 방향의 포물선 추세 신호가 될 수 있습니다. 횡보 시장에서 가격은 하단 밴드의 상단에 도달한 후 상단 또는 하단 밴드에서 중간 20선 이동 평균으로 되돌아갑니다. 가격이 20일 이동평균선을 넘으면 상승세를 나타내고 있고, 가격이 20일 이동평균선보다 낮으면 하락세를 나타냅니다.

“According to Bollinger, the bands should contain 88-89% of price action, which makes a move outside the bands significant. Technically, prices are relatively high when above the upper band and relatively low when below the lower band. However, “relatively high” should not be regarded as bearish or as a sell signal. Likewise, “relatively low” should not be considered bullish or as a buy signal. Prices are high or low for a reason. As with other indicators, Bollinger Bands are not meant to be used as a stand-alone tool. Chartists should combine Bollinger Bands with basic trend analysis and other indicators for confirmation.” – StockChartscom

Bollinger에 따르면 밴드는 가격 행동의 88-89%를 포함해야 하며, 이는 밴드 외부로의 이동을 의미 있게 만듭니다. 기술적으로 가격은 상위 밴드를 초과할 때 상대적으로 높고 하위 밴드 아래에서 상대적으로 낮습니다. 그러나 "상대적으로 높음"이 약세나 매도 신호로 간주되어서는 안 됩니다. 마찬가지로 "상대적으로 낮음"은 강세 또는 매수 신호로 간주되어서는 안 됩니다. 가격이 높거나 낮은 데에는 이유가 있습니다. 다른 지표와 마찬가지로 볼린저 밴드는 독립 실행형 도구로 사용할 수 없습니다. 차티스트는 볼린저 밴드를 기본 추세 분석 및 확인을 위한 기타 지표와 결합해야 합니다.” – 스톡차트닷컴
