python版CTP商品期货交易类库 测试版 如有BUG 欢迎提出，作者QQ ： 359706687 小小梦 1、2017.4.25 更新：增加 if (insDetail.MaxLimitOrderVolume == 0) 条件判断，有些期货公司服务器 会返回0 值，特此处理。共修改3处 【1】self.pollTask 【2】function Cover 【3】function Open

shenglinqian 谢谢，我看到有些函数的使用和API文档中的说明不一致，是函数有更改么？
小小梦 哦 是的 确实是写错了，我赶紧修改了， 感谢提出宝贵的建议和问题 ^^ 。
小小梦 您使用的 是 python 3 么， 测试了 python 2 或者 3 ， GetName() 返回的 都是 字符串， 您测试的 截图 可以发下么 ， 我分析下。
小小梦 修改成这样试下。这个 除数0 应该是做了 判断的，原来是判断 dealAmount 是0 就直接 赋值 0. https://dn-filebox.qbox.me/b06b4b5b08c28c198dbecefa91ad3692d96dce54.png
小小梦 哦 好的 感谢 提出问题 ， 我检查下。
云中游 貌似是20171218新的托管者引发的问题,换回老版就没问题了. python版CTP商品期货交易类库（支持2/3 测试版） 369 "price" : (0 if task["dealAmount"] == 0 else (pos["Cost"] - task["preCost"]) / (pos["Amount"] - task["preAmount"])), 貌似这句有问题,如果Amount=preAmount就会使分母为 0
小小梦 in pollTask ZeroDivisionError: division by zero 检查 pollTask 函数 ， 代码中 除数 为 0 了
shenglinqian ok，了解了，谢谢！
小小梦 哦~ 明白了。我解释下 1、 这个模板里面的 GetPosition 是一个自定义函数 ， 并不是 API 文档的 exchange.GetPosition , exchange.GetPosition 是平台API 。 2、 open 里面调用的就是 API 文档中的 Buy / Sell 函数， API 文档中 描述了 必要的2个参数 ，实际上 在API文档中 描述的必要参数后增加 参数 就作为 日志中的 附带信息 打印出来了，你可以看下此 策略模板的 代码， 在调用 Sell / Buy 的时候，在价格 、数量 这两个参数后 传入的都是 提示性的信息。
shenglinqian 比如api文档中写GetPosition是没有参数的，我看代码里是可以加参数的 然后buy和sell函数文档里是两个变量，代码里的open下的buy和sell 都不止2个变量
小小梦 哦 ？ 具体是哪一个 ，应该都是一致的，可以贴一下 我看看。
