Credit Acceptance: RSI overbought, Bollinger Bands narrowing on 15-minute chart.

Credit Acceptance's 15-minute chart has triggered an RSI (Relative Strength Index) reading above the overbought threshold and Bollinger Bands have narrowed to a point where they are no longer providing adequate support. This suggests that the stock price has risen too quickly and is now higher than its fundamental value, with a decreasing magnitude of price fluctuations.
