BRAR
BR指标又称买卖意愿指标,同AR指标一样也是反映当前市况下多空双方相互较量结果的指标之一。它们的区别在于AR指标是以当日的开盘价为均衡价位,而BR指标选择的是前一天的收盘价。双方的分界线是100,100以上是多方优势,100以下是空方优势。
BR值的波动较AR值敏感,当BR值在150-300间波动时,属盘整行情,投资者应保持观望。当BR值高于400以上时,股价随时可能回档下跌。此时,投资者应选择时机卖出;当BR值低于150时,股价随时可能反弹上升。此时,投资者应选择时机买入。
一般情况下,AR可以单独使用,BR则需与AR并用,才能发挥效用。具体应用及研判的法则如下:
①AR和BR同时急速上升,意味着股价峰位已近,持股者应注意及时获利了结。
②BR比AR低,且指标处在150至100以下的区域,投资者可考虑逢低买进。
③BR从高峰回跌,跌幅达1或2倍时,若AR无警戒讯号出现,应逢低买进。
④BR急速上升,AR盘整小回时,应逢高卖出,及时了结。
根据笔者多年看盘的经验,该指标虽不适合捕捉到大底部,但是灵活运用该指标,却能够抓住局部底部,特别适合做反弹。
