I've written a custom backtesting program. I have been running it with a mysql database I've filled with data I bought from Pi Trading. That is all fine, but I would like to double check my results with another set of data - just to be careful. I am not entirely confident of this data.
Anybody know of a good source for historical 1 minute data for stocks? Tick data would be OK but that gets huge. I would like to have data back at least 5 years. I am willing to pay for it. I have searched the net but have not found the solution.
BTW, here's a general "thanks" for all the stuff I've learned from this forum over the years. Creating and running my backtesting and ATS setups is hugely satisifying - monetarily, intellectually and emotionally. Anbody who thinks the long hours, risk tolerance and skills needed for this are easy is a fool.
