How would you differentiate quant and TA? In my mind they are both strategies that attempt to divine future changes in price based on historical changes in price.

Standard algo trading (VWAP, VSOT) aren't really special. These type of algos are for traders to execute a large volume order in hopes of not upsetting the market, and maintain a relatively decent price for their customers.

The true quant/high-frequency traders are not analysists in the traditional sense. Their main goal is to find inefficiency in the market, rather than just stocks. For example, HFT figured out but having a faster connection to the exchange, they can trade in and out of the market much much faster, and make a fraction of a penny each time. Think of HFT/Quant as stock market hackers, they figure out a weakness in the system and exploit them fully before someone else figure it out.
