XLM - Pullback?

٤ يناير ٢٠١٨

I'm looking at the hourly chart and it seems that XLM have been respecting trendline on the way up, but now it seems to have crossed bellow it, with MACD also crossing could this mean that we have entered retracement ?? If so, does anyone have any idea on how big of a retracement we are talking about ?
