有人能建议如何正确使用R IBrokers-reqOpenOrders吗?
> tws=twsConnect(clientId=66,host='localhost',port='7497')
> reqOpenOrders(twsconn=tws)
TWS Message: 2 -1 2104 Market data farm connection is OK:usopt
TWS Message: 2 -1 2104 Market data farm connection is OK:usfarm
TWS Message: 2 -1 2106 HMDS data farm connection is OK:ushmds
TWS OrderStatus: orderId=565 status=PreSubmitted filled=0 remaining=1 averageFillPrice=0
TWS OrderStatus: orderId=566 status=PreSubmitted filled=0 remaining=1 averageFillPrice=0
我想得到一份我未完成订单的清单。上面的命令挂起,必须停止它才能返回到R提示符。谢谢
我想我得到了。该功能需要在IBrokers包的几个文件中实现。在processMsg.R
中,我们需要在零件if(curMsg == .twsIncomingMSG$OPEN_ORDER)
中添加以下内容:
if(curMsg == .twsIncomingMSG$OPEN_ORDER) {
msg <- readBin(con, "character", 84)
x = eWrapper$openOrder(curMsg, msg, timestamp, file, ...)
return(x)
接下来,在eWrapper.R
中实现函数openOrder
,如下所示:
openOrder <- function(curMsg, msg, timestamp, file, ...) {
x = e_open_order(msg)
return(x)
}
然后在eventHandlers.R
中,按如下方式更改e_open_order
:
`e_open_order` <- function(msg) {
contents = msg
...
return(eoo)
}
该事件处理程序很好地将TWS返回消息中的数据引导到适当的结构twsContract、twsOrder和twsOrderState中。然后,我创建了以下功能:
gs_GetOpenOrders = function(twscon){
# Check if connected to TWS
if(!is.twsConnection(twscon))
stop('requires twsConnection object')
else
con = twscon[[1]]
# Send message requesting open orders
ver = "1"
writeBin(c(.twsOutgoingMSG$REQ_OPEN_ORDERS,ver),con)
# Receive message with content of open orders
ewr = eWrapper()
socketSelect(list(con),FALSE,NULL)
msg = list()
k = 0
while(TRUE) {
curmsg = readBin(con, character(), 1)
if(length(curmsg)==0)
break
if (curmsg==.twsIncomingMSG$OPEN_ORDER){
k = k+1
msg[[k]] = processMsg(curmsg,con,ewr)
}
else
processMsg(curmsg,con,ewr)
}
return(msg)
}
结果是列表变量msg
。列表的每个元素依次是一个列表,其中包含结构twsContract、twsOrder和twsOrderState中的未结订单数据。从那里,人们可以简单地以任何所需的方式获取、显示和使用数据。IBrokers中几乎所有其他功能看起来都是如此,只是其中一些已经实现了。
我在包IBrokers_0.9中创建了一个受reqAccountUpdates.R启发的函数,它返回一个未结订单列表。
.reqOpenOrders <- function(twsconn) {
if( !is.twsConnection(twsconn))
stop('requires twsConnection object')
con <- twsconn[[1]]
VERSION <- "1"
writeBin(c(.twsOutgoingMSG$REQ_OPEN_ORDERS,VERSION), con)
}
reqopenorders_cb <- function(twsconn) {
.reqOpenOrders(twsconn)
open_orders=list()
con <- twsconn[[1]]
eW <- eWrapper()
while(TRUE) {
socketSelect(list(con), FALSE, NULL)
curMsg <- readBin(con, character(), 1L)
if(curMsg == .twsIncomingMSG$OPEN_ORDER){
open_orders[[length(open_orders)+1]]=processMsg(curMsg, con, eW,
timestamp=NULL,file="")
} else {
processMsg(curMsg, con, eW,timestamp=NULL,file="")
}
if(curMsg == .twsIncomingMSG$OPEN_ORDER_END)
break
}
return(open_orders)
}
