What do you mean with "problem"?
That is entirely up to you to define your strategy! The Ichimoku is at its heart just a few moving averages. Just using the indicator, does not make a strategy or trading plan nor does it guarantee success or failure, irrespective of the Time-Frame or Symbol being used.
In fact, no indicator at all is "good" or "bad", until it is used in conjunction with other aspects that make up a Strategy and Trading Plan, including Risk and Money Management.
