D1 - Price broke below the bullish channel, the price then moved lower and has created lower lows.
H4 - Price is moving inside a small range, we may now look to sell the top of the range with bearish evidences.
If you want to be more conservative then wait for the price to break below the bottom of the range and then you may look for sells with more bearish evidences (evidences could be in the form of candle stick patterns, false breaks, trend line breakout etc… supporting the bearish view).
