The large uptrend line can be duplicated to see all other parallel levels where the market have found support/resistance. The price have then been ranging horizontally, after having broken this large uptrend line. Now it is time to consider the probability of seeing the market price fall a bit. The break of the lower part of the rectangles will validate that probability. In the other side, two natural upper resistance formed by the top of the two squares. Probability of pullback down from those points.
Any break of the square up or down will be a nice entry point. Time to take profits for investor to reduce exposition and come back stronger after the probable share price fall.
