三副主副套图撒泪倾出短 线 操 作 要 则
只要一只股票的攻击力消失，无论它是否下跌，都必须离场———这是短线操作的原则。在实战中，股价处于高位，后市下跌空间大，获利机会已消失，即必须止损。若股价尚在循环周期的低位和上升通道之中，则应在支撑位处补仓待变。如股价是在下降通道中运动，下方无重要技术支撑时则严禁补仓，而只能果断斩仓止损。大盘涨，同时上涨股只数大于下跌股只数，说明涨势真实，属大盘强，短线操作可积极进行。若大盘涨，下跌股只数反而大于上涨股只数，说明有人在拉抬指标股，涨势为虚，短线操作要小心。大盘涨跌时成交量显示的条件：大盘涨时有量，跌时缩量，说明量价关系正常，短线操作可积极展开。大盘涨时小量，跌时放量，说明量价关系不利，有人诱多，短线操作宜停或小心展开。实战可于放量当日买进1／3仓位。
若股价冲高回落既可获利出局，也可在回落2天后补仓。
