A flat wave wave structure. Slowly everybody gets tired of this continuous fall. The figure shows a "main wave" motion (green) and indicates a "response wave" (red). Both types have dual wave structure. The "Main Wave" (0A) section is 25 percent larger than the second (BC) section. The same can be said about the "response wave" structure. The "response wave" (0A) is 25 percent larger than the current waveform (BC) second wave structure. If it is correct the idea of the GPRO price is rising slowly, the target price is 7.99 usd.
