Hi investors/speculators/day-traders/rich/poor/gay/straight/transgenders, I'm trying to get accurate historical data on NYSE/NASDAQ stocks with (1 sec to 15 sec ticks) for the last 30 days and couldn't find a great service to do it.
I use Interactive Brokers, and they have a historical data request API. I tried using that using Excel-DDE, but the data I got was super inaccurate. I got stocks trading for 57 dollars at 10:40am while Yahoo and Google shows they were trading at 55 dollars at that time. Why is it so inaccurate? I have NASDAQ/NYSE NBBO level1 market data package with them.
Has anyone been successful getting reliable historical data from Interactive Brokers? If so, how? If not so, what's the best place to seek this data?
Thank you all very much, especially the transgenders!
