在ibapi包的client.py脚本中提供了方法reqAccountSummary，该方法可以请求以下标签信息

accountountType

gatway.api.client.reqAccountSummary(1001,"All","TotalCashValue")
gatway.api.client.reqAccountSummary(1001,"All","accountountType")
gatway.api.client.reqAccountSummary(1001,"All","NetLiquidation")
gatway.api.client.reqAccountSummary(1001,"All","TotalCashValue")
gatway.api.client.reqAccountSummary(1001,"All","SettledCash")
gatway.api.client.reqAccountSummary(1001,"All","AccruedCash")
gatway.api.client.reqAccountSummary(1001,"All","BuyingPower")
gatway.api.client.reqAccountSummary(1001,"All","EquityWithLoanValue")
gatway.api.client.reqAccountSummary(1001,"All","GrossPositionValue")
gatway.api.client.reqAccountSummary(1001,"All","RegTEquity")
gatway.api.client.reqAccountSummary(1001,"All","SMA")
gatway.api.client.reqAccountSummary(1001,"All","InitMarginReq")
gatway.api.client.reqAccountSummary(1001,"All","MaintMarginReq")

gatway.api.client.reqAccountSummary(1001,"All","FullAvailableFunds")
gatway.api.client.reqAccountSummary(1001,"All","FullExcessLiquidity")
gatway.api.client.reqAccountSummary(1001,"All","LookAheadNextChange")
gatway.api.client.reqAccountSummary(1001,"All","LookAheadInitMarginReq")
gatway.api.client.reqAccountSummary(1001,"All","LookAheadMaintMarginReq")
gatway.api.client.reqAccountSummary(1001,"All","LookAheadAvailableFunds")
gatway.api.client.reqAccountSummary(1001,"All","LookAheadExcessLiquidity")
gatway.api.client.reqAccountSummary(1001,"All","HighestSeverity")
gatway.api.client.reqAccountSummary(1001,"All","DayTradesRemaining")
gatway.api.client.reqAccountSummary(1001,"All","Leverage")
gatway.api.client.reqAccountSummary(1001,"All","$LEDGER")
gatway.api.client.reqAccountSummary(1001,"All","$LEDGER")

但是该函数不直接返回请求标签对应的账户信息，而是通过ibapi包下的wrapper.py脚本中的

accountSummary()方法，将请求的信息写入日志文件，所以可以在此处设置成员变量接受这些信息，需要确认一下totalchashvalue是不是净值的意思，如果是的话，直接获取该值就行了

可以直接在此处调用http方法把各标签对应的值传递到服务器

解决了净值传输的问题，当前持仓细节放在后面

下面的任务是追踪一个交易订单指令下达时，整个的交易执行流程，以及交易执行结果【成功还是失败，失败的话，需要报告交易失败的原因】
