@Sunx 大神！请帮忙！ ！！！！！！！！！！！！！！！！！ 计算：超额现金 = Max{0, [(货币资金 + 交易性金融资产) - Max(0, 流动负债合计 - (流动资产合计 - (货币资金 + 交易性金融资产)]}。 我啰嗦一下：1，第一步判断比较0和（流动资产-（流动资产-（货币资金+交易性金融资产））的大小，取两者中交大的一个数； 2，再拿(货币资金 + 交易性金融资产) 和1比较的结果相减； 3，再拿0和2的结果比较，取两者中交的值为“超额现金”。 # 超额现金计算 import pandas as pd df =get_fundamentals(query(valuation,indicator,balance,income,cash_flow),date='2017-9-2') df=df.fillna(0.00001)#将NAN付值0.00001是为了计算，不然空值太多，没法用。 货币资金+交易性金融资产 df['全部货币性资产']=df['cash_equivalents']+df['trading_assets'] (流动资产合计 - (货币资金 + 交易性金融资产) df['非货币性流动资产']=df['total_current_assets']-df['全部货币性资产'] 流动负债合计 -非货币性流动资产 df['流动负债减去非货币性流动资产']=df['total_current_liability']-df['非货币性流动资产'] initial_stocks =list(df['code']) for stocks in initial_stocks: if df.流动负债减去非货币性流动资产.values>0.0: df['过桥参数1']=df['流动负债减去非货币性流动资产'] else: df['过桥参数1']=0.0 df['过桥参数2']=df['全部货币性资产']-df['过桥参数1'] if df['过桥参数2']>0.0: df['超额现金']=df['过桥参数2'] else: df['超额现金']=0.0 #############################333 ValueError Traceback (most recent call last) <ipython-input-5-d74cfe8d80ca> in <module>() 14 df.market_cap.values.sum() 15 for stocks in initial_stocks: ---> 16 if df.流动负债减去非货币性流动资产.values>0.0: 17 df['过桥参数1']=df['流动负债减去非货币性流动资产'] 18 else: ValueError: The truth value of an array with more than one element is ambiguous.

@成都老柴 没怎么看懂，你16行那个中文混编的代码能跑么？先拿字母替代了试试

这里的【运行中】和【已完成】是不是反了？ ![1.png][1] [1]: https://image.joinquant.com/acfadf5dc08fac275adf48dca1c73b7c

@JoinQuant-PM

@飞天猫大浩 是的。

@JoinQuant-PM 您好，最近用这个框架发现比之前的速度慢了很多，发现在回测列表中的回测已经结束，但是ipython中还是没有执行完，而且延迟还挺久的。不管是什么策略，就算回测区间只有2-3天，框架中也需要跑5分钟才结束。请问是什么问题？

今天运行时，参数设置没用了，所有参数运行结果都跟策略原始代码的结果一样。呜~~~~~~~~~~

我也是，参数设置没用了，从昨天改版开始的，希望管理员看看@JoinQuant-PM

@JoinQuant量化课堂 您好！用这个框架运行一直提示list index out of range，不知道什么原因。 【已完成|运行中|待运行】: [0|0|8]. [0|6|2]. [0|6|2]. [0|6|2]. [0|6|2]. [0|6|2]. [0|6|2]. [0|6|2]. [0|6|2]. [0|6|2]. [0|6|2]. [0|6|2]. [0|6|2].

@代达罗斯之殇 呃，我也不太清楚了。你at一下量化课堂？

@代达罗斯之殇 我和你一样的情况，请问解决了吗

还没 你那边解决了吗

好了

多策略管理很需要这个！~赞

楼主，出现一个新问题：运行时提示：The kernel appears to have died. It will restart automatically。重启研究也是这样。有没跟我一样情况的？怎么解决？
