使用说明：
趋势判断：BOLL中轨线是股票的短期移动平均线，通常用来判断股票的趋势。当股票价格位于BOLL中轨线之上时，说明股票当前处于一个相对强势的状态，可能存在上涨趋势。当股票价格位于BOLL中轨线之下时，说明股票当前处于相对弱势状态，可能存在下跌趋势。
震荡区间：BOLL指标的上轨线和下轨线构成了一个价格波动的区间范围。当股票价格超过BOLL上轨线时，说明股票价格较高，可能存在卖出机会；当股票价格低于BOLL下轨线时，说明股票价格较低，可能存在买入机会。在震荡市中，投资者可以根据BOLL指标的上下轨位置来制定买卖策略。
超买超卖：当股票价格远离BOLL中轨线时，即价格超过BOLL上轨线或低于BOLL下轨线，可能表明市场出现了超买或超卖情况。这时候，投资者应该警惕价格的逆转可能，考虑及时调整仓位或采取相应的止盈止损策略。
选股参考：投资者可以结合BOLL指标与其他技术指标和基本面分析，来进行股票的选股。例如，当股票处于上升趋势且价格位于BOLL中轨线之上，同时伴随着较高的交易量和良好的基本面，可能是一个优质的买入时机。
止损策略：在使用BOLL指标时，投资者应该设置合理的止损点位，避免因价格波动超过预期范围而造成较大亏损。
