Would you not say that the daily is overbought here? Using a standard fast (10,10), I read the value on NDX at 82.72, maybe not quite oversold because the signal line hasn't caught up. But on a slow, the signal line never got all the way down which would support the case that this is really just a countertrend up before going down some more. My tweeked stochastics show even more clearly.
Or do you just want to see it really cooked?
Edit: Correction, I was looking at QQQ daily, not NDX. NDX is at 79.xx Still, standard stochs never got low enough for my taste.
