twsContract should allow me to retrieve Historical data, Market data and place orders to any market on Ibokers.
Trying to identify GBP.USD pair:
contract <- twsContract(0,"GBP","CASH","IDEALPRO", "","0.0","USD","","","",NULL,NULL,"0")
Does not return any data with:
x <- reqHistoricalData(tws,contract)
Can someone guide me how to find FOREX currency pair data?
