支撑位（Support Level）是指股价下跌到某一水平时，获得买盘支撑而止跌回升的价格位置。压力位（Resistance Level）则是指股价上涨到某一水平时，遇到卖盘压力而无法继续上涨的价格位置。在英语中，我们可以说：“The support level is the price point where buying interest prevents the price from falling further, while the resistance level is the price point where selling pressure prevents the price from rising further.”
