Currently esignal has 30_Minute Charts back 120 days. So using 6/1/07 start date now. They have a BETA that will not post bid-ask, only prices, it will go back more. Have data on QID_QLD going back to Mid Jan 2007, but it is messy. I plan to post SYSTEM results as MIKE,FROG,SS,others come up with new stocks. Why? Looking for good stocks for system.
