Yes the 13ema/34ema makes for a good Fib combination but with more whipsaws than the 34ema/50ema which I prefer as I always like to see the 50ema on a chart anyways. I guess if I was a purist I'd use the 34ema and 55ema which are both Fib numbers. But there are more whipsaws with the 34/50 and the signals are close with the 34/50's and with less whipsaws so prefer them. Here is a Dec Emini/Dec Crude Ratio chart. Don't know it it tells you anything much. I was surprised to see the Emini outperform Dec Crude since April actually. Wouldn't have thought with the SPX getting so trashed during this time frame until I made this chart.
