Update August 7, 2020 The downwards thrust and harmonics seems to point the reversal lower than $3.37. The support could be from any of the following 1. Historical support of $2.86 2. $2.28 (78.6 Fibonacci level co-incites with the price pattern completion AB=CD pattern and the trend-line support-Green line) Refer to purple box 3. 5 waves to complete pattern C (estimated projections)
The reversal is possible at any of this above levels. Look for reversal candle stick and uptick in volume and momentum. ** publishing another chart please refer for visuals
