The previous resistance trend-line has been broken and seems to provide some support after it.
There could be a nice breakout coming if we break out from this triangle.
I am currently long from the bottom of the (green+red)trend-line and will add to the position if we manage to breakup above the resistance of the yellow trend-line.
A rejection candle like a 15+min on the top of the channel indicates weakness as can be seen in the previous price action.
Just like a on a support-level or support-line can be a sign.
Go with the break
