Divergence or lag?

AUDCHF is basically inverted EURAUD. So if we get new highs in EURAUD we should see new lows in AUDCHF,
but we havn't got that ATM.
Such divergence could signal that the break out is a fake one, but the market could be in lag.

I'm not saying that AUD is bullish, but I won't want to sell until we see new lows in AUDCHF and NZDUSD in contrast to AUDUSD.
