Generalizations about currencies, time frames and Ichimoku

Any generalizations experienced traders have on the efficacy of Ichimoku in specific currency pairs for different time frames?

I am developing some generalities here. For example, ADX doesn’t seem to work well on the pound/yen for shorter time periods, too volatile.

Ichimoku supposedly doesn’t do well with euro/swiss. Any suggestions on stronger correlations between Ichimoku and currency pairs/time frames? I’d like to drill down and customize the indicator tools to specific discreet packages…and am testing my hypotheses to confirm.

Thanks for any assist.
