IV Charts
You have to select
1) The market your stock is in
2) The ticker of your stock
You are then shown a stockprice chart of the ticker you have chosen with the
choice of 5 overlays and 5 indicators, these can be shown above or below the
stockprice chart. The Overlays and Indicators are explained below.
The middle chart is used to show Implied Volatilities, Put, Call and both combined and
historical volatility. This chart is used to determine if IV is high, low or moderate. You
can also compare IV and the HV20 (historical volatility 20 day average), this will tell
you if options are cheap or expensive.
The third chart shows the daily put and option volume chart. Extremes may indicate
a trend change.
Overlays
Simple Moving Average
A moving average which gives equal weighting to each day's stock price data
Should be used when the stock is 'trending' i.e. bullish or bearish trend
The first variable is the number of days used for the Simple Moving Average
Exponential Moving Average
A moving average which places a greater weighting to recent data
Should be used when the stock is 'trending' i.e. bullish or bearish trend
The first variable is the number of days used for the Exponential Moving Average
Bollinger Bands
An overlay developed by John Bollinger. Three lines with the middle line being a SMA Simple
Moving Average. The upper band is the SMA plus 2 standard deviations. The lower band is the
SMA minus 2 standard deviations. Standard deviation is a statistical concept, 2 standard deviations
ensures that 95% of the price data falls between the upper and lower band.
If the stockprice is above the upper band, it is considered overextended and should fall. The reverse
is true if the stockprice falls below the lower band.
If the bands are tight together it indicates that stock volatility is low, if the bands are very wide it conversely
indicates that stock volatility is high. This volatility indication can be used to help decide which option strategy would be appropriate.
The first variable is the simple moving average. The second variable is the number of standard deviations
Bollinger Bands (area)
The same as Bollinger Bands, but the area between the upper & lower band is shaded in.
The first variable is the simple moving average. The second variable is the number of standard deviations
