After 2 years of QQQQ trading system development I have some verified by Walk Forward Test solution for QQQQ trading and like offer it for customers (google more about what is Walk Forward Test, but in two words - WalkForwardTest is the consecution of the system tests on some unknown/future data (next trading day in my solution)). Estimate 1700 days QQQQ Walk Forward Test enclosed. I like notice - minimal capital for this system is $1M because system trades 3 times each 2 trading days (it mean around $50 commission per day or more...) Please, send me private message if you have interested.
