IMO you may want to close your short as we have resistance and hammer candle is forming on 4H chart , your support trend line is a little off. Try lining it up with the wick of the bull candle 13/09 01:00:00. I like to follow this rule for my trendlines, 1. Connect the line from body to body / or / 2. Connect line from wick to wick. Creates a more accurate view!!
