And here is a recent example of 2 time frame type stuff.
Note that during the resistance phase in March, the 15 min was doing a much better job than the 30 min.
But during this decline, the 15 min looks sloppy with overshoots, but the 30 min is spot on with the 900 and the 200...
Never, ever, just watch 1 time frame if you want all the clues possible....
NDX 15 min
NDX 30 min
