There are two shaded circles on each of the Weekly charts below of YM, ES, NQ & TF. The first contains the infamous "Fat Finger" day in 2010. The second contains the downdraft following Standard & Poor's downgrade of the U.S. credit rating in 2011. For all you wave traders, we may be approaching the final segment of a Wave 5 on the Weekly timeframe. It may be prudent to be prepared for sudden "Fat Finger" downdrafts, particularly if the TF is not able to break out and hold above 2011 highs.
In this regard, the support levels, which coincide with the upper portion of the 2011 downdraft, are 12500 for YM, 1330 for ES, 2420 for NQ…850 represents that level for TF, but it hasn't even closed above it yet, so it's holding as resistance.
