Hi, When using IB as realtime datafeed, I can't get the symbols for Dow, Nasdaq and sp500.
Inside TWS, they are INDU, COMP and SPX respectively. However, when I tried to download the data from Amibroker, after I entered any of the above symbols, it will tell me the symbol is not valid. I contacted IB, they just told me I should use INDU, COMP and SPX. Not very help information. Anyone here is able to retrieve the indices using IB as the data feed? Thanks.
