I have been trading only stocks but recently have looked at trading futures as well for the 23 hour daily bar. Since index futures open in the evening, I can catch Asian and European markets before U.S begins creating a good sized daily range.
I believe discretionary 'day traders' should only trade AWAY from open prices. See for yourself, create a bracket around a daily open price based on the recent average range of the open to high/low (the smaller of the 2). In other words, if it passes that distance odds are you are on the right side to catch a full avg daily range.
Nothing else you are seeing on a chart provides this kind of R:R
