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.
