版本1.9.34.116
將OCO
(又名 One Cancel Others)添加到回測庫中。
筆記
這僅在回測中實現,還沒有針對實時經紀人的實現
筆記
更新為1.9.36.116
版本。盈透證券支持StopTrail
、 StopTrailLimit
和OCO
。
OCO
始終將組中的oco
一個訂單指定為參數ocoStopTrailLimit
:代理模擬和IB
代理具有 asme 行為。指定:price
作為初始止損觸發價格(同時指定trailamount
),然後plimi
作為初始限價。兩者之差將決定limitoffset
(限價與止損觸發價之間的距離)
使用模式試圖保持用戶友好。因此,如果策略中的邏輯決定現在是發出訂單的時刻,則可以像這樣使用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
簡單的。 1 st order o1
將類似於組長。通過使用oco
命名參數指定o1
, o2
和o3
成為OCO 組的一部分。看到片段中的註釋表明o3
也可以通過指定o2
成為組的一部分(它已經是組的一部分)
隨著小組的成立,將發生以下情況:
- 如果該組中的任何訂單被執行、取消或到期,其他訂單將被取消
下面的示例展示了OCO
概念。帶有情節的標準執行:
$ ./oco.py --broker cash=50000 --plot
筆記
現金增加到50000
,因為資產達到4000
的價值並且1
件的 3 個訂單至少需要12000
貨幣單位(經紀人的默認值為10000
)
用下面的圖表。
這實際上並沒有提供太多信息(它是標準的SMA Crossover
策略)。該示例執行以下操作:
當快速 SMA 穿過慢速 SMA 向上時,發出 3 個訂單
order1
是一個Limit
訂單,將在limdays
天(策略參數)到期,close
價減少一個百分比作為限價order2
是一個Limit
訂單,到期時間更長,限價更低。order3
為Limit
單,進一步降低限價
因此order2
和order3
的執行不會發生,因為:
-
order1
將首先執行,這應該會觸發其他人的取消
或者
order1
將過期,這將觸發其他訂單的取消
系統保留 3 個訂單的ref
標識符,並且僅當notify_order
中的三個ref
標識符顯示為Completed
、 Cancelled
、 Margin
或Expired
時才會發出新的buy
在持有一些柱的頭寸後簡單地退出。
為了嘗試跟踪實際執行,會生成文本輸出。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
發生以下情況:
第一批訂單發出。訂單 1 到期,訂單 2 和 3 被取消。正如預期的那樣。
幾個月後,又發出了另外一批 3 份訂單。在這種情況下,訂單 49
Completed
,50 和 51 立即取消最後一批和第一批一樣
現在讓我們檢查一下沒有OCO
的行為:
$ ./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
就是這樣,這並不多(沒有訂單執行,也不需要圖表)
該批訂單下達
訂單 1 到期,但由於策略獲取了參數
do_oco= False
,訂單 2 和 3 不屬於OCO
組因此,訂單 2 和 3 不會被取消,並且因為默認的到期增量是
1000
天后,它們永遠不會隨著樣本的可用數據而到期(2 年的數據)系統從不發出第二輪訂單。
