Error code 200 IB API

[Soon2Bgreat]

Hello i just recently downloaded IB's API and am having trouble getting market data.

It tells me i have error code 200 which is no security definition is found for this request.

Does this mean i've input the symbol information incorrect, or it's a technical (software, harware) security issue.

I tried getting data from their sample symbols, which are already setup and i get the same error message...so i don't think i've input the symbol incorrectly.

I'd appreciate any input or a point towards the right direction.

Thank you for any help.

It means the symbol (or rather Contract) information is incorrect or incomplete.

Small java sample:

Contract contract = new com.ib.client.Contract (
    ticker, 
    contractType, 
    expiry, 
    0, 
    "", 
    "", 
    exchange, 
    currency, 
    "", 
    null, 
    "");

Where contractType is "STK" or "FUT".

eg

Contract contract = new com.ib.client.Contract (
    "ES", 
    "FUT"
    "200803", 
    0, 
    "", 
    "", 
    "GLOBEX",
    "USD",
    "", 
    null, 
    "");

You will need to fill in some of the other arguments for an option contract.
