Does anybody know where I could get a list of which currency pairs have historically had the smallest gap between their cyclical highs and lows? And/or where the frequency of bicycles is greater? I am not sure if I am wording my question correctly.

I mean, as an example, when you look at the weekly or monthly chart of AUDCAD or GBPUSD, the gap between major highs and lows is only roughly 30% in comparison to 40-50% for pairs such as AUDUSD and EURGBP. Additionally, the frequency of upward and down cycles in AUDCAD and GBPUSD is greater than AUDUSD and EURGBP.

Is there a simple source that I can refer to? Thanks!
