It's even simpler than that and knowing this alone can make you a lot of money. There are TWO types of market: Trending market and rangebound market. This sounds like just another platitude, but this is the OBVIOUS that is not so obvious to 99% of the traders.
yep .. you have to start there. if you are not sure then wait till it is clear. if it is trending look for a corrective move
the simplest trade is look for two leg move to a support /resistance or key level and exit on the breakout
once you have two points on a chart draw a trend line extend it and then observe the market. this is the best way to learn about what market does.
