As far as I know, technical traders build a lot of their edge by looking at a lot of charts. Some gravitate towards specific setups, the most common one I've seen being the breakout after volatility contraction. Others like to trade only specific tickers that provide good trading ranges and they're familiar with all the moves that ticker makes. Of course, they're not mutually exclusive and many people do both styles. But I'm curious to get opinions on pros/cons of each.
