Java IBrokers-我如何向IBrokers发送100000:。placeOrder？

我正在使用iBroker在IDEALPRO上打开澳元兑美元的订单

下面是一个语法，它非常适合我销售90000台：

# 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，我尝试通过此API调用下100000的订单：

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

命令失败了

我在我的日志中看到：

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

一个简单的解决办法是下2份50000英镑的订单

我在寻找其他解决办法的线索

我怀疑错误在于IBrokers向API发送的是1e+05，而不是100000。

我刚刚通过谷歌“禁用R中的科学符号”找到了答案。答案是，我在打电话之前插入这行语法

options（“scipen”=4）

如果允许，我会正确回答。尝试传递字符串而不是数字。i、 e.

“100000”

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)
