Dow was first to create averages for market monitoring and analysis. They are still in use, I hear.

Later when data handling became easier (50's), the indicators were perfected. We use two basic kinds (absolute like MACD and relative like STOCH) and rarely are price and volume mixed (See ergonomics as an exception).
From the 80's to mid 2006 an era of Quant's seemed to dominate in setting the inductive standard for data processing. The Black Swan result they have achieved and demonstrated has more or less stifled their era of contribution.
As it turns out the minority control the markets. This is counterintuitive and befuddles most people who are not science or technically oriented.
The technical analysis applied to those who trade has been done with about the same skills and approaches the financial industry did to enhance its sales and fees oriented profit making. The two major "effects" demonstrated by traders (sympatheric) who are CW oriented is the Bohr Effect and the Fight or Flight Response. Both are indicative of a "predicting" orientation. Prediction is not necessary and it turns out a NO NO for making money because of the human factors.
In my expereince, since 1957, TA hasn't changed. It is the better way to be equipped to take the market's offer. It also has the benefit to the trader of being a parasympathetic orientation .
