potential short confirmed by red candle with long wick

reaching a major resistance point the price line at 45.17 was rejected and the price came down with a red candle and long wick to indicate for a potential short position at 45. I expect it to re test support at 42.
-RSI mixed to bearish
-45.69 reached 0.618 retracement
-previous support now resistance at 45.17-45.71
