@TANOTFA, thanks to your excellent charts (and @436hilltop Post#:15866596) I have been able to figure out maxi's numbers. (In the "too hard" basket for me without your work )

So we've got a confluence of four calculations which point to 25-Aug possibly being a significant bottom.
1. Maxi's MetaStock 423.6% on the XAO
2. My unconventional 423.6% extension on the XJO (from 4-Aug top)
3. Semilog trendline from 9-Aug-2011 support at 4947 on the XJO
4. A possible Elliott ABC on the XJO:
Wave A: (3-Mar, 5996.9) to (9-Jul, 5383.7)
Wave B: (9-Jul, 5383.7) to (4-Aug, 5727.7)
Wave C: (4-Aug, 5727.7) to (25-Aug, 4928.3)
Wave C =~ 1.272*Wave A, which is a common Fib ratio for ABC corrections.

PLUS my computer has generated a BIG coloured turning point bar at 4946.
All of this must mean something, surely!
