I am willing to pay ~$50 USD for 1-minute data for the previous 2-3 years of QQQ and SPY. I request *.csv or *.txt files that are comma delimited with date, time, open, high, low, close and volume. I can pay via Paypal or Paydirect via Yahoo! Eel
That site does not offer QQQ and/or SPY in 1-minute format for the previous 2-3 years. For anyone interested, my offer still stands. Eel
