看透主力倍缩洗盘（通达信公式 源码 选股） 一、形态特征
在连续数日洗盘的末端，出现一根（以上）比前一日缩量一半的量柱，表明下跌动能在迅速减弱。
副图中黄柱对应缩量一半的量柱，红三角标志着趋稳或止跌，黄s三角开始反弹，是介入标志。
二、原理分析
它充分体现了“三先规律”，是发现主力行踪的好助手。
1.卖在买先。只有有人卖出，才能有人买进，才能堆出量柱。突然缩量一半，说明愿意卖出的人和卖出的量迅速减少。
2.价在量先。只有价咯让人满意，才会有人卖出，即使是亏钱割肉，也要割在自己能接受的价位上。突然缩量一半，说明这时的价咯不能让人满意，要想买到筹码，就只能提高股价。
3.庄在散先。任何散户都不可能凭借手中微弱的资金实力拉涨或打压某只股票，所以，量柱就是庄家的标志，突然缩量一半，这是庄家用“休克疗法”来制造或测试底部，庄家隔岸观火，放任自流，机会一到，定会拉升。
三、使用技巧
1.缩量一半之前要有缩量柱，最好有长阴短柱。
2.缩倍调整后出现极阴次阳、长阳矮柱，双胜阴时，调整结束。
3.下面有黄金线、峰顶线等支撑最好。
