So Here is my confluences for taking the short:
1. Price refused to break the supply area at 15 mins (OB)
2. the current reaction at that level produced a 1H closure with a wick within the range of previous candle close
3. 15 mins closed with a wick within the range of the previous candle.
4. 3 minutes produced a riverbank pattern
The above was sufficient to go for a short for 2R
