Summarizing my points:
1- showing divergence with price action, and it is rebounding for the third time in oversold territory
2- broken on April 19th with volumes
3- Today closing H4 candle is a piercing line candle, which opened below the lower of the previous candle, and closed approximately at half of the body of the same previous handle.
Not visible from this chart, if yu have a look at the monthly candles, you'll see that the last three candles have lower volumes, and this is a strong sign to me, that we are just few days/weeks away from recoverying an uptrend with higher volumes.
