Predicting the market and reacting to the market direction can absolutely co exist, from what I've come to understand, many successful traders do a bit of both but some might not even tell you.
Each time you enter a trade based on your analysis, you're technically predicting that the market will move in your favour.
The problem I don't think is predicting but being stubborn with your prediction. If the market is moving against you and you refuse to react because you feel you're right with your prediction, you'll most likely get liquidated.
Predicting the I think is what makes you a trader but reacting when necessary is what actually keeps you in the market.
Yes, trying to predict is literally what traders are doing and there is no scenario where we are going to end up with a profit if we are not careful about the direction. So if you can predict very well then you are going to be profitable, because knowing what's going to happen, before it happens, is the job of a trader.
But of course reacting to it is the one that will make the actual profit because if you can predict but just write it on a piece of paper and do nothing about it then how could you profit? You need to be able to predict the market and then react to it at the right time otherwise you are going to end up with losing a lot of money, or at least losing a chance to make some profit from it.
