This is a pretty important time I've tried to chart the important supports/resistances that will suggest bullish or bearish as it passes them, hope you like this chart.
3750 is important also because the chart shows that it is reacting to this psychological level, and of course because it is a psychological level.
Safer entry the higher resistances it breaks however. Catching knifes is a real fine art and one that can be tricky even for the more educated. So play this level at your own risk, or wait till a bit higher maybe above 3800 to rebuy if it is passing that level with ease.
