You can do all sorts of things with data if you can get it into Amibroker.
This is the latest thing I've come up with... In the US there is an indicator called VIX, which is a composite of IV's of the options of a range of large stocks. It is something a great many tecnicians take notice over there.
Well I've created an Aussie version OZIV for want of a better name. It is a composite of liquid option IV's across arange of stocks in different sectors.
Google VIX and you'll quickly find the interpretation of ther indicator, but basically it is regarded as a fear indicator... It peaks at market bottoms and bottoms in bull markets.
Looking at OZIV, is steadily trending upwards, with intermediate peaks and troughs reverse correlated to XJO peaks and troughs as you'd expect.
But what about this gradual trend toward higher IV's?
