I’ve got about the same story as you, but I went long on GBPCHF and eventually stopped out instead of taking the profit.
Per CCFp (different indicator from Dennis’ numbers), over the past N days or so, both currencies were converging to center. So, even though GBPCHF was in the #1 spot, GBP was strengthening and CHF was weakening.
That’s my take, too, according to this (H4 chart):
So, I’ll be watching Dennis’ numbers for a crossover, but I need to see a currency move significantly before I place a trade.
