bearmountain I use custom indicies to help
spot divergance between a normal price or cap weighted
index like the dow/sp500..
e.g you could have a potential failed double bottom pattern that
takes out the 2nd low on the sp500, but on the custom index
you may notice that the 2nd bottom hasnt been took out yet.
Also as a 2nd example you can use the custom index to create
market breadth studies like tick, uvol/dvol, trin etc that are a better representation and update faster than the usual nyse/nasdaq.
