SP 500 2 or 3 days short before trying a move up

The last session shows a shooting star, that shadow seems to be generated by “High not sold” because of the short term target of Long position. That high has touched the supertrend too, with a good reaction.
Tomorrow USA is closed, so then rather volume will not be great.
If it goes up immediately after the openein (++) I would look for a pattern to go short for intraday without excluding the overnight.
