I agree with much that is said here. Hindsight is 20/20. Patience is a virtue. Usually you find out it's an untradeable market after some realized losses. lol I can't wait for this market funk to end! For me this is the worst in my 20+ years in the markets in short term and longer term time frames.
Most traders trade because they think too much. And they are thinking of entering the market for themselves. You need to think before trading - when you are writing a trading plan or strategy for yourself. And then, like a robot - there is a signal entered, there is no signal you sit and wait. It's like fishing. You only need to pull the fish when it bites.
The non-tradable market is very shorthand. I know a trader who can trade almost any market, even when he is in a protracted flat. Yes, he earns less, more risks. I can't do that, my trading strategy is different.
