SP500 can rise back above 4k

The end of last week was a good one for stocks with a Pin Bar reversal on Thursday and a strong bullish day on Friday(also the weekly candle is a Pin Bar)
At this moment SP500 is facing a confluence of resistances given by the horizontal 3900 and the falling trend line and a break above these could lead to further gains above 4k and to the next resistance at 4090.
I'm bullish this index and I'm looking to buy dips.
A drop under 3700 would negate this scenario
