As the GBPNZD becomes rampant amid news sentiment you can be a buyer or a seller.
And I can tell ya, I'd much rather be a seller.
If you simply look back over time you shall notice that sellers have been far better off (Shorting at highs over the last few YRS) VS Buying.
Long zones are only determined plainly by where people are getting long. This is practically never after a move up has already occured.
So trade in line with history.. It helps.
