Strategy Description

冰山委托指的是投资者在进行大额交易时，为避免对市场造成过大冲击，将大单委托自动拆为多笔委托，根据当前的最新买一/卖一价格和客户设定的价格策略自动进行小单委托，在上一笔委托被全部成交或最新价格明显偏离当前委托价时，自动重新进行委托。 例子: 如果单次均值浮动点数设置为10那么: 每一笔委托的数量为其单次委托平均值的90%~110%，委托价格为最新买1价*（1-委托深度），在上一笔委托全部成交后再进行新的一笔委托，在最新成交价格距离该笔委托超过委托深度*2时自动撤单并重新进行委托。在策略总成交量等于其总委托数量时停止委托。当市场的最新成交价格高于其最高买入价格时停止委托，在最新成交价格重新低于最高买入价后恢复委托。
