Andy,
With regards to the first one. imho, it was a decent long set-up on both the YM and ES (although 1098.5 was the top of yesterdays value area - so perhaps not quite so perfect an ES set-up). The issue with any long entry at that point was the relative weakness of the NQ (compare the position of ES, NQ and YM against their opening range to see what I mean). For any trade, particularly one where you are expecting new highs or lows (and in this case where it would be expecting the ES and YM opening range to be taken out), YM, ES and NQ all have to be making a decent move from the same relative position of strength or weakness (imho of course).
With regards to the seond one, I guess you are right. I found it a difficult one. For me, 1093.5 (ES) and 10038-10042 (YM) was a spot I was looking for a potential long. Once again the relative weakness of the NQ scuppered that plan, with 1381.5-1382.5 providing the perfect NQ short when it retraced back to there.
Seemd to me it was never going to be a "clean" day because the indices were slightly out of sync, any strenth in the YM being made up for by weakness in the NQ, with ES just sitting in the middle.
Before the open, I was anticipating that 10038-42 (YM), 1093.5-94.5 (ES) and 1381.5-82.5 (NQ) would all get "hit" at around the same time for the mother of a long. Lack of "sync" between them kind of scuppered that plan though.
