AAKASHAYA PATRA SEVEN STAR SMART EDUCATION SERIES PART – 9 :
Bollinger Bands
Bollinger Bands is volatility indicator invent by "John
Bollinger" in 1980.There is a three parallel bands running with the price
(Candlestick) which help us to Identity Stock Trend, Stock Volatility and Stock
Over Bought and Over Sold Position Middle Band of the Bollinger Band calculated
on the basis of 20 Period Simple Moving Average (SMA), and Calculation of the
Upper Band and Lower Band based on +/-2 Slandered Deviation
The detail calculation of the
Bollinger Band as below :
BOLU=MA(TP,n)+m*s[TP,n]
BOLD=MA(TP,n)-m*s[TP,n]
where:
BOLU=Upper Bollinger Band
BOLD=Lower Bollinger Band
MA=Moving average
TP (typical price) = (High+Low+Close)÷3
n=Number of days in smoothing period (typically 20)
m=Number of standard deviations (typically 2)
s[TP,n]=Standard Deviation over last n periods of TP
Here we have to understand how to use Bollinger Band on
Candlestick Chat which help us to refine our trading decision to identify stock
trend, support and resistance, volatility,stock over bought and over sold
position
Use of Bollinger Band
to Identify the Trend :-
As we know, in the calculation of the Bollinger Band, we
use 20 period Simle Moving Average ( 20 SMA) When ever stock start to trade
Upper side of the Middle Line of the Bollinger Band, we can consider it as a
buying opportunity and its assume that stock now may show Upper side movement
(Up Trend) from its current position. Similarly,When stock start to trade below
side of the middle band of the Bollinger Band, its a sign of the down fall /
Down trend from its current position.
Use of Bollinger Band
to Identify Support and Resistance : -
As we already discussed in detail in earlier Smart
Investment issue about Support and Resistance When ever stock price comes to
touch Bollinger Band, Band will be act as a Support or Resistance subject to
Stock Price comes from Upper Side or Below Side It means if stock price comes
from lower band side to touch middle band, middle band act as a resistance line
for stock price similarly if stock price comes from Upper Side to touch middle
band,middle band will be act as support line for that stock price
Bollinger Band Squeeze
and Expansion :-
Bollinger Band are compress and expand as per the
volatility, if Bands are Squeeze it means its a very low volatility market and
breakout or expansion is expected in near future When ever we received break
out in Bollinger Band, direction of the break out will play an important role
in future price movement, if we received Up ward side breakout it means it
expected price will be go in Upward direction and if we received breakout down
side it means price will be go in down ward direction, accordingly band are
expand and its show the volatility and price movement in the stock.
