时间加权平均算法
- 将委托数量平均分布在某个时间区域内;
- 每隔一段时间用指定的价格挂出买单(或者卖单)。
- 买入情况:买一价低于目标价格时,发出委托,委托数量在剩余委托量与委托分割量中取最小值。
- 卖出情况:卖一价高于目标价格时,发出委托,委托数量在剩余委托量与委托分割量中取最小值。

冰山算法
- 在某个价位挂单,但是只挂一部分,直到全部成交。
- 买入情况:先检查撤单:最新Tick卖一价低于目标价格,执行撤单;若无活动委托,发出委托:委托数量在剩余委托量与挂出委托量中取最小值。
- 卖出情况:先检查撤单:最新Tick买一价高于目标价格,执行撤单;若无活动委托,发出委托:委托数量在剩余委托量与挂出委托量中取最小值。
