Friday was a tricky day on the US indices if you were not up with your 15min Charts. The one that was of main interest to me was the 15min ES, where the 15min DP supported the low and provided a platform off which a rally late in the day unfolded. So this changed the prior down trend to an uptrend for the shorter term charts.
Yes, this picture was not as clear on the other e-minis, but the 15min ES did find support at this DP, so you should, have been wary about shorts and looking for longs on the other e-minis as well. Even if there are minor differences in the individual e-minis, they are basically all related, so larger degree trends (if the 15min charts are similar) can "generally" apply to all 4 .....
