Most of the best/Professional traders I have read about and know of personally do not predict what will happen they trade what is happening.
New/Amateur traders always want to predict, they want to argue about their beliefs and why something must happen or will happen.
Most Professional traders are rich because they are flexible, they have no strong opinions and are just looking at possibilities and ready to take a set up, buy a break out or short a break down.
A Amateur trader believes that ‘conviction’ about a trade is important, holding through an adverse move is usually a bad idea, especially if a key level is reached that is showing the trader that they are wrong.
A Professional trader is waiting for some price level to trigger their entry then another price level to trigger their exit.
A Amateur trader is trading off a belief and has no real exit plan most the time because they are sure that they are right.
The money I have pulled out of the market over the past 10 years has come from trading price action not predicting. I have entered at high probability moments on break outs above resistance levels. I have trailed my winning trend trades with a stop and sold when the trend reversed through key short term support.
When I was wrong I stopped out for a small loss, when I was right I let the winner run up for a very big win. I am always trend hunting, always taking my high probability trades, always cutting losses short, and when not seeing a great trade doing nothing and waiting.
