At this moment, we have 2 main possibility which either this downtrend refering to wave 4 or just only a. The strength and volume preferably indicates for wave 4 but it just look to simple for wave 4. But overall, unless the retracement critical line is taken, this wave 4 scenario would still be valid. Expecting for a bullish reversal signal later from BSTS for wave 5. Please take notes for all the critical lines. Good luck.
