ETrade Java API问题 - previewEquityOrder和previewOptionOrder抛出ETWSException

标签： java etrade-api

我正在使用ETrade Java API。我能够使用大部分功能，但我遇到了 previewEquityOrder 和 previewOptionOrder 功能的问题。以下是我调用这些函数时得到的错误消息/异常：

URL : https://etwssandbox.etrade.com/order/sandbox/rest/previewequityorder
? Java exception occurred:
com.etrade.etws.sdk.common.ETWSException
at com.etrade.etws.sdk.common.ETWSUtil.constructException(ETWSUtil.java:9)
at com.etrade.etws.sdk.core.ConnectionUtils.invoke(ConnectionUtils.java:90)
at com.etrade.etws.sdk.core.ConnectionUtils.invoke(ConnectionUtils.java:32)
at com.etrade.etws.sdk.client.OrderClient.previewEquityOrder(OrderClient.java:145)

对于 previewOptionOrder ：

URL : https://etwssandbox.etrade.com/order/sandbox/rest/previewoptionorder
? Java exception occurred:
com.etrade.etws.sdk.common.ETWSException
at com.etrade.etws.sdk.common.ETWSUtil.constructException(ETWSUtil.java:9)
at com.etrade.etws.sdk.core.ConnectionUtils.invoke(ConnectionUtils.java:90)
at com.etrade.etws.sdk.core.ConnectionUtils.invoke(ConnectionUtils.java:32)
at com.etrade.etws.sdk.client.OrderClient.previewOptionOrder(OrderClient.java:167)

以下Java代码可以重现该问题。您可以使用以下命令在Mac上编译此代码。在Windows机器上，将“：”替换为“;”作为分隔符。

javac -classpath "./commons-codec-1.3.jar:./commons-httpclient-3.1.jar:./commons-httpclient-contrib-ssl-3.1.jar:./commons-lang-2.4-javadoc.jar:./commons-lang-2.4-sources.jar:./commons-lang-2.4.jar:./commons-logging-api.jar:./commons-logging.jar:./etws-accounts-sdk-1.0.jar:./etws-common-connections-1.0.jar:./etws-market-sdk-1.0.jar:./etws-oauth-sdk-1.0.jar:./etws-order-sdk-1.0.jar:./log4j-1.2.15.jar:./xstream-1.3.1.jar:" test.java

您可以使用以下命令从命令行运行已编译的类：

java -classpath "./commons-codec-1.3.jar:./commons-httpclient-3.1.jar:./commons-httpclient-contrib-ssl-3.1.jar:./commons-lang-2.4-javadoc.jar:./commons-lang-2.4-sources.jar:./commons-lang-2.4.jar:./commons-logging-api.jar:./commons-logging.jar:./etws-accounts-sdk-1.0.jar:./etws-common-connections-1.0.jar:./etws-market-sdk-1.0.jar:./etws-oauth-sdk-1.0.jar:./etws-order-sdk-1.0.jar:./log4j-1.2.15.jar:./xstream-1.3.1.jar:" test <consumer_key> <consumer_secret>

您需要传递ETrade使用者密钥和使用者密钥作为命令行参数来运行它。

请注意，身份验证部分可以通过获取帐户列表进行验证。

我在ETrade社区论坛上发布了这个，但该论坛不是非常活跃。我还向ETrade发出了请求，但尚未得到答复。如果我从他们那里得到解决方案，我会回来把它发布在这里。同时，我们非常感谢任何帮助。

答案 0 :(得分：0)

在调试上面的代码之后，我发现问题是我将ReserveOrder设置为TRUE但是我没有提供所需的ReserveOrderQuantity。我从ETrade开发人员平台指南的Java代码片段中获得了上述代码。这显然是他们文档中的错误。
