I have come up with a an extremely simple EOD system for trading SPY. This system works very well for SPY which tends to be trendless. Other ETFs like DIA, IWM works too but not very good. This a End of Day (EOD) system. I will give the signal at the end of day. The trade will be entered at the close of the following trading day. There will be plenty of time for any one who like to verify the working of this system.
