I got burned in IRBT calls using just the 3-16-16. I got to wondering if a 5-34-34 would have warned to use puts, and I think it would have. Notice the green histogram sloping downward heading for a fall. Likewise, a red histogram can be sloping upward heading for a rise. So, now I'm using 3-16-16 as Accelerator Oscillator and 5-34-34 as Awesome Oscillator.
