BTC retesting downtrend resistance after an initial breakout.
Since the confirmation of a top in bitcoin and a confirmation of a lower high and therefor downtrend, almost exactly a year later BTC broke out of the downtrend and rallied to 21.5k before a macro news event causing fear and mass selling back down to local lows of 17k. which also coincides with a retest of the trendline.
If BTC can hold and rally off these lows it would be a strong place to start building for the next bull market. However if this area of support fails then a further drop down to 14k is possible.
