支撑位即是指标的价格在下跌时可能遇到的支撑，是交易者认为买方力量开始反超卖方使得价格在此止跌或反弹上涨的价位； 阻力位则是指在标的价格上涨时可能遇到的压力，是交易者认为卖方力量开始反超买方而使得价格难以继续上涨或就此回调下跌的价位。 请用英语的经济金融类专业术语将中文翻译成英文

Support level refers to the potential level at which a financial indicator may encounter support during a price decline. This is the level at which traders believe that the buying pressure may begin to overtake the selling pressure, causing the price to stop falling or rebound.

Resistance level, on the other hand, refers to the potential level at which a financial indicator may encounter resistance during a price increase. This is the level at which traders believe that the selling pressure may begin to overtake the buying pressure, making it difficult for the price to continue rising or causing it to fall back.
