And the lagging span line (chikou span line) is actually trying to cross the ichimoku cloiud in one-hour timeframe. If the lagging span line gets over the kumo then that would mean a confirmation of the uptrend at least in one-hour timeframe (for hourly investors). If the lagging span line gets over the ichimoku cloud then one will have then to watch on 4 hour timeframe and daily timeframes to identify potential resistances for the price and the lagging span line.
