CareDx's 15-minute chart signals MACD Death Cross, KDJ Death Cross.

According to CareDx's 15-minute chart, two technical indicators have triggered bearish signals. The MACD (Moving Average Convergence Divergence) has crossed below its signal line, also known as a "death cross," indicating a potential downward trend in the stock price. Additionally, the KDJ (Stochastic Oscillator) has also crossed below its signal line, a "death cross," which further supports the notion that the momentum of the stock price is shifting towards the downside. Therefore, it is likely that the stock price may continue to fall and potentially decrease further.
