Which indicators are the latest and greatest thing?
Candlestick charts are 300 years old.
The concept of On-Balance Volume was invented in the late 1930s. It was originally calculated out by-hand and graphed on paper.
The concept of Fibonacci is over a thousand years old, dont have the exact dates on me.
Dow Theory is over 100 years old.
Most of the technical indicators were invented between 1900 and 1960.
Bollinger Bands were invented in the 80s.
The problem is not with the indicators themselves, but the people who use and interpret them. The men who invented these indicators were very intelligent and educated who had professional experience with the markets. They invented these indicators for a certain purpose and a certain market.
Indicators cannot be understood or learned overnight. It does take a while to learn the purpose and usage of each.
As for the "squigly lines", technical charts have been used since the start of trading. Jesse Livermore mentions the usage of such charts during trading in the 10s and 20s.
John Bollinger is a rich and famous man who has successfully used his Bollinger Bands. Many traders use the bands on a daily basis and the theory behind them is very sound.
