Lets see what the low of the week will be. Probably that will determine the lower border.
The green line touch (as a swing low) would determine a good symmetry for this one. Since the main diagonal is pointing DOWN, the odds are that an upward break is most likely to occur.
Looking good so far.
We have other clues that show that a reversal (correction) is imminent. Those being price action being inside a bullish wedge formation and some confirmed MACD/RSI bull divergences already published here.
