MultiAlpha 缺少 API 进行后续处理

[bnfan]

使用 multi_simluation 后得到的返回值没有 alpha_id 无法进行后续处理

例如：

调用simulate 后返回

{"children":["2ckQwVdpM4T49oaknnT7tY1","1Y814j1uq594bPHfTzwARU1","3W6v34g4b59p1ef14lCAG1Nn","2U0N0M5F94sn1nlaE4vg5Px","4nf1U54O74yu9Ib10Y73MYZ8","3j1YHd36t4MdcBWPE4DuwhH","2bQMp794Z4LeaxLYPbkjHxP","4teJf3Xo5595UP1bjrt3hCB","1HLOkT52W4RYaHVFkh3eiyk","2CjBe8Zr5aBalcPS41wLcn"],"type":"REGULAR","settings":{"instrumentType":"EQUITY","region":"USA","delay":1,"language":"FASTEXPR"},"status":"COMPLETE"}

只有"children"的id，wqb 缺少 API 进一步获得这些 simulation 的 alpha_id
