observation on the weekly timeframe

hey guys i was making an observation on the weekly time frame using the Vlf and i notice that the signal line the yellow line havent yet cross over the volume length(green line) not yet giving us a buy signal. so i think this rally will go back to as low as 2500 if we fallow fib levels. i could be wrong though but that just an observation i made. eventually i think it will crash back, specially with the Economic Recession upon us. this is only an idea please make your own analysis before making any decision. good luck
