版本1.9.34.116
将OCO
(又名 One Cancel Others)添加到回测库中。
笔记
这仅在回测中实现,还没有针对实时经纪人的实现
笔记
更新为1.9.36.116
版本。盈透证券支持StopTrail
、 StopTrailLimit
和OCO
。
OCO
始终将组中的oco
一个订单指定为参数ocoStopTrailLimit
:代理仿真和IB
代理具有 asme 行为。指定:price
作为初始止损触发价格(同时指定trailamount
),然后plimi
作为初始限价。两者之差将决定limitoffset
(限价与止损触发价之间的距离)
使用模式试图保持用户友好。因此,如果策略中的逻辑决定现在是发出订单的时刻,则可以像这样使用OCO
:
def next(self): ... o1 = self.buy(...) ... o2 = self.buy(..., oco=o1) ... o3 = self.buy(..., oco=o1) # or even oco=o2, o2 is already in o1 group
简单的。 1 st order o1
将类似于组长。通过使用oco
命名参数指定o1
, o2
和o3
成为OCO 组的一部分。看到片段中的注释表明o3
也可以通过指定o2
成为组的一部分(它已经是组的一部分)
随着小组的成立,将发生以下情况:
- 如果该组中的任何订单被运行、取消或到期,其他订单将被取消
下面的示例展示了OCO
概念。带有情节的标准运行:
$ ./oco.py --broker cash=50000 --plot
笔记
现金增加到50000
,因为资产达到4000
的价值并且1
件的 3 个订单至少需要12000
货币单位(经纪人的默认值为10000
)
用下面的图表。
这实际上并没有提供太多信息(它是标准的SMA Crossover
策略)。该示例运行以下操作:
当快速 SMA 穿过慢速 SMA 向上时,发出 3 个订单
order1
是一个Limit
订单,将在limdays
天(策略参数)到期,close
价减少一个百分比作为限价order2
是一个Limit
订单,到期时间更长,限价更低。order3
为Limit
单,进一步降低限价
因此order2
和order3
的运行不会发生,因为:
-
order1
将首先运行,这应该会触发其他人的取消
或者
order1
将过期,这将触发其他订单的取消
系统保留 3 个订单的ref
标识符,并且仅当notify_order
中的三个ref
标识符显示为Completed
、 Cancelled
、 Margin
或Expired
时才会发出新的buy
在持有一些柱的头寸后简单地退出。
为了尝试跟踪实际运行,会生成文本输出。其中一些:
2005-01-28: Oref 1 / Buy at 2941.11055 2005-01-28: Oref 2 / Buy at 2896.7722 2005-01-28: Oref 3 / Buy at 2822.87495 2005-01-31: Order ref: 1 / Type Buy / Status Submitted 2005-01-31: Order ref: 2 / Type Buy / Status Submitted 2005-01-31: Order ref: 3 / Type Buy / Status Submitted 2005-01-31: Order ref: 1 / Type Buy / Status Accepted 2005-01-31: Order ref: 2 / Type Buy / Status Accepted 2005-01-31: Order ref: 3 / Type Buy / Status Accepted 2005-02-01: Order ref: 1 / Type Buy / Status Expired 2005-02-01: Order ref: 3 / Type Buy / Status Canceled 2005-02-01: Order ref: 2 / Type Buy / Status Canceled ... 2006-06-23: Oref 49 / Buy at 3532.39925 2006-06-23: Oref 50 / Buy at 3479.147 2006-06-23: Oref 51 / Buy at 3390.39325 2006-06-26: Order ref: 49 / Type Buy / Status Submitted 2006-06-26: Order ref: 50 / Type Buy / Status Submitted 2006-06-26: Order ref: 51 / Type Buy / Status Submitted 2006-06-26: Order ref: 49 / Type Buy / Status Accepted 2006-06-26: Order ref: 50 / Type Buy / Status Accepted 2006-06-26: Order ref: 51 / Type Buy / Status Accepted 2006-06-26: Order ref: 49 / Type Buy / Status Completed 2006-06-26: Order ref: 51 / Type Buy / Status Canceled 2006-06-26: Order ref: 50 / Type Buy / Status Canceled ... 2006-11-10: Order ref: 61 / Type Buy / Status Canceled 2006-12-11: Oref 63 / Buy at 4032.62555 2006-12-11: Oref 64 / Buy at 3971.8322 2006-12-11: Oref 65 / Buy at 3870.50995 2006-12-12: Order ref: 63 / Type Buy / Status Submitted 2006-12-12: Order ref: 64 / Type Buy / Status Submitted 2006-12-12: Order ref: 65 / Type Buy / Status Submitted 2006-12-12: Order ref: 63 / Type Buy / Status Accepted 2006-12-12: Order ref: 64 / Type Buy / Status Accepted 2006-12-12: Order ref: 65 / Type Buy / Status Accepted 2006-12-15: Order ref: 63 / Type Buy / Status Expired 2006-12-15: Order ref: 65 / Type Buy / Status Canceled 2006-12-15: Order ref: 64 / Type Buy / Status Canceled
发生以下情况:
第一批订单发出。订单 1 到期,订单 2 和 3 被取消。正如预期的那样。
几个月后,又发出了另外一批 3 份订单。在这种情况下,订单 49
Completed
,50 和 51 立即取消最后一批和第一批一样
现在让我们检查一下没有OCO
的行为:
$ ./oco.py --strat do_oco=False --broker cash=50000 2005-01-28: Oref 1 / Buy at 2941.11055 2005-01-28: Oref 2 / Buy at 2896.7722 2005-01-28: Oref 3 / Buy at 2822.87495 2005-01-31: Order ref: 1 / Type Buy / Status Submitted 2005-01-31: Order ref: 2 / Type Buy / Status Submitted 2005-01-31: Order ref: 3 / Type Buy / Status Submitted 2005-01-31: Order ref: 1 / Type Buy / Status Accepted 2005-01-31: Order ref: 2 / Type Buy / Status Accepted 2005-01-31: Order ref: 3 / Type Buy / Status Accepted 2005-02-01: Order ref: 1 / Type Buy / Status Expired
就是这样,这并不多(没有订单运行,也不需要图表)
该批订单下达
订单 1 到期,但由于策略获取了参数
do_oco= False
,订单 2 和 3 不属于OCO
组因此,订单 2 和 3 不会被取消,并且因为默认的到期增量是
1000
天后,它们永远不会随着样本的可用数据而到期(2 年的数据)系统从不发出第二轮订单。
