We often predict that the current trend will hold for a long period of time or we prematurely predict that the current trend will reverse. We sometimes predict that supports or resistances will hold other times that they will break and enter a trade accordingly.
We should keep in mind that prices fluctuate in waves in any timeframe. Prices can reverse any time. Just because the price movement reverses it doesn't mean that the stock market will crash. We always have to look at the longer trend.
Instead of predicting we can anticipate price movements. Our anticipation is based on our analysis and statistics. At support and resistance levels we don't need to predict just to observe price movements and react accordingly. All we have to do is to follow the price. Before we enter a trade we can establish these support and resistance levels and plan our exit strategy ahead of time.
