As long as the prediction came up with a good analysis, it's good to consider as one of your future references on your next trading action. The market is unpredictable and too volatile, therefore, at least we don't just want to rely on instinct, emotion, guesses etc. on what would be the best possible actions. Don't approach trading like that.

Chart reading is obviously not 100% accurate but since it uses some tools and indicators, we can somehow able to predict some scenarios and design a strategy on that situation.
