EURONEXT:ACKB has been channeling sideways for about 520 days.
It has a strong resistance at 156. Currently in oversold territory (stock rsi), weekly and daily.
Thus why I'm short.
I've used: www.turtlebc.com for this analysis, and followed every wave of buy percentage that passed 50% and marked in on the chart with an arrow, you can clearly see it was always followed by a bullish trend.
Good luck :)
