IBrokers -我是如何发送100000到IBrokers:::.placeOrder的？

Question

我使用IBrokers在IDEALPRO上打开澳元-美元的订单

这里的语法对我来说很好，可以卖9万美元：

# myscript.r

.libPaths("rpackages")
library(IBrokers)
myconid = 3
twsobj  = twsConnect(myconid)
myaud = twsCurrency("AUD",currency="USD",exch="IDEALPRO",primary="",strike="0.0",right="",local="",multiplier="",include_expired="0",conId=myconid)
Sys.sleep(2)
myorderid = as.integer(reqIds(twsobj))
print(myorderid)
Sys.sleep(2)
myorderid = as.integer(difftime(Sys.time(), "2014-10-30", units = "secs"))
Sys.sleep(2)
IBrokers:::.placeOrder(twsobj, myaud, twsOrder(myorderid,"SELL", 90000, "MKT"))
Sys.sleep(4)
twsDisconnect(twsobj)

接下来，我尝试使用这个API调用下100,000份订单：

IBrokers:::.placeOrder(twsobj, myaud, twsOrder(myorderid,"SELL", 100000, "MKT"))

命令失败了。

我在日志里看到了这个：

java.lang.NumberFormatException: For input string: "1e+05"

一个简单的解决办法是为50000下2份订单。

我在寻找其他解决办法的线索。

我怀疑错误是IBrokers将1e+05发送到API而不是100000。

# myscript.r

.libPaths("rpackages")
library(IBrokers)
myconid = 3
twsobj  = twsConnect(myconid)
myaud = twsCurrency("AUD",currency="USD",exch="IDEALPRO",primary="",strike="0.0",right="",local="",multiplier="",include_expired="0",conId=myconid)
Sys.sleep(2)
myorderid = as.integer(reqIds(twsobj))
print(myorderid)
Sys.sleep(2)
myorderid = as.integer(difftime(Sys.time(), "2014-10-30", units = "secs"))
Sys.sleep(2)

# my workaround:
options("scipen"=4)

IBrokers:::.placeOrder(twsobj, myaud, twsOrder(myorderid,"SELL", 190000, "MKT"))
Sys.sleep(4)
twsDisconnect(twsobj)
