After encountering the downtrend line, the lowest price came to 19305.00. A pin bar (arrow) appears at this bottom, and the price of the subsequent k bars also closes above the closing price of the pin bar at 19801.04. Indicating that here is an effective support, and there is a chance to reverse the trend. If the price closes above the resistance range of 20000~20245.35 in the future, BTC has a chance to come to the downtrend line (blue line). However, it is also possible for BTC to make a second bottom near the support 19305.00~19561.01, and then break up. -
