The coin being charted is not confirmed to go down. It just signals the start of a long consolidation or gradual downtrend. Notice the down consolidations are getting flatter. It could go flat, gradual down, or track the slow uptrend white line for days while candles get shorter. The last big drop didn't happen until the histogram was negative for almost a month.
As always, not investment advice. Do your own due diligence before placing a trade.
