It pulls a band one [ at a time ] up and down, and vertical width is decided by standard deviation on the basis of a moving average line.
The view of Bollinger Band, and usage
Generally the view of this indicator is a view that price fluctuation is
carried out between the vertical bands of Bollinger band.
上下のバンドに価格が接近、又は到達した場合、そこで反転すると判断してUPバンドに価格が
到達した場合は売り、Lowバンドに価格が到達した場合はその逆で買いという見方です。
又、価格が上下バンドを抜けた場合は抜けた方向への力が強いと判断するという見方もあります。
・価格がBollinger bandのUPバンドを上抜けた時点で上昇圧力が強いと判断
・価格がBollinger bandのLowバンドを下抜けた時点で下降圧力が強いと判断
The calculation method of Bollinger Band
Upper Band =Moving average+Standard deviation
LOWバンド=Moving average-Standard deviation
Standard deviation=√(period*期間内の終値の2乗の合計−期間内の終値の合計の2乗)÷(期間×(期間−1))
