Hi Guys: I am looking to get TICK BY TICK HISTORICAL time and sales data for some symbols like (SPY- QQQ) for up to 7 years ago. I need to get tick by tick BID / ASK and trades. Do you know any company that offer these historical data with a reasonable price? Please guide me where I can get these kind of data. ( with a reasonable price) Thanks
