Querying trades from IB using reqExecutions

Question

Im trying to query trades from IB by using function reqExecutions:

library(IBrokers) 
con <- twsConnect(clientId=1)
id <- reqIds(con) 
Order <- twsOrder(orderId=id, action="BUY", totalQuantity = 1, orderType="LMT", lmtPrice = 600, tif="GTC") 
placeOrder(con, twsSTK("AAPL", Order)
print(reqExecutions(con, reqId = as.character(.Last.orderId), ExecutionFilter = twsExecutionFilter(clientId="1")))

although trades are executed in IB, it always returns NULL.

Answer 1

Can't you just use reqOpenOrders?

Warning: The following will execute a trade. Make sure you are connected to a paper trading account before running this code!

library(IBrokers) 
#con <- twsConnect(clientId=1)
con <- ibgConnect(clientId=1)
id <- reqIds(con) 
Order <- twsOrder(orderId=id, action="BUY", totalQuantity = 1, orderType="LMT", 
                  lmtPrice = 600, tif="GTC") 
placeOrder(con, twsSTK("AAPL"), Order)

> reqOpenOrders(twsconn=con)
