The chart indicates the weekly channel. Now see the Bottom ascending trendline and the moneyflow trend line below the candle chart (In Yellow). Thats a bit longer. The smaller one indicated in RED LINE (3-5 weeks) which, I think is also a bullish indication. The money flow index basically indicates how strong are sellers and buysers just like RSI but its Volume based too. IMO the sellers seem minimal. Apparently, thats the reason of the spike.
