Quote from traderdragon2:
The correct weather analogy would be.
You look out the window and see rain clouds forming. So before walking out the door, you pickup the umbrella.
Some people here are trying to convince us that you didnt just make a prediction
The trading version:
You look at your screen and see a stock rising. So you press the buy button anticipating it will keep going up.

I will re-state my first post: We are dealing with the duality of trading.
Yes prediction is done. BUT it is done during the testing/researching/grail search phase. A person comes up with some rules that he believes to be true about certain conditions. He says, If I see abc, then xyz happens. Yes, this is prediction. Looking for cause and effect. Or effect and trying to find cause.
NOW WHEN THE PERSON MOVES INTO THE REALM OF TRADER PREDICTION IS OVER. He becomes a signal taker. He goes long for no other reason than abc exist. The out come of abc is unknown and not knowable. And no longer the point. He takes signals because to not take them would be to call himself a liar. He excepts the uncertainty of any individual trade.
But he believes in his success because he has structured the probabilities in his favor. ALL PREDICTION WAS DONE PRIOR TO BECOMING A TRADER.
Now there is a higher level of trader who does looks at reality and not a system. He sees the rain drops and thus grabs an umbrella.
Most of us are at the stage where we see the rain clouds and grab an umbrella. But as stated, we do not grab the umbrella because we predict rain. We grab the umbrella because or method of weather understanding has told us to grab the umbrella. (the duality)
This higher state of trading, trades in the moment. Price is rising , then go long. Price is falling, be short. The future will take care of itself, and the market will take care of the trader. This type of trader doesn't want what he wants, he wants what the market wants. And what does the market want? To keep on doing what it is already doing.
But he does not know what the future holds, so he places his focus on what IS real-what is actually happening now.
So while some take the umbrella out at the first sign of a grey cloud, the master level trader takes the umbrella out when he gets wet. He has less baggage to carry and his path is smoother. The others are carrying umbrellas and raincoats, only too find out that the early clouds dissipate and the sun shines brightly.
