For people who have been day trading stocks for 2, 5, 10, 20 years: 1. How have intraday price channels changed over the years? 2. Do price channels last shorter or longer than in the past? (I'm specifically referring to the smallest channels visible on 3-min or 5-min charts that often form and dissolve within 30 minutes to 2 hours) 3. Do the trend lines retain their integrity more rigidly now or in the past? Have "head fakes" increased or decreased? 4. Are the answers to these questions different for stocks with different liquidities or share prices? For example: Have high or low volume stocks' price channels become more or less predictable due to the increased numbers of retailers on home computers, tighter spreads, the advent of bots which target some stocks more than others, etc.? 5. How do the questions above relate to other instruments such as CL or ES?
