Combining pairs to save pips

I my broker has the following spreads:

EUR/USD 2 pips
NZD/USD 4 pips
EUR/NZD 20 pips

How can I combine the first two to get an effective EUR/NZD position?

Buy EUR and Sell NZD = Long EUR/NZD

Sell EUR and BUY NZD = Short EUR/NZD

With a 20 pip spread on EUR/NZD, I think you might have a good idea here.

No kidding, this is brilliant when you think about it. Reducing 20 pips to 6 pips... Very interesting..

Thanks for the replies!

How do I calculate lot sizes to even out?

You want to have the same pip value on each pair ??

Well, with my br0ker, I can trade any trade size. So, I would just open a ticket and adjust the trade size until the pip values match. (FxGame)

Or, you could try to determine which currency has more potential to move the farthest and adjust your trade sizes accordingly. (Bigger trade on the higher probability)

Also, since you are going to enter two trades.... you could treat them as separate trades, instead of seeing them as a cross. If one seems to be performing better, ummmm.... leave it open longer ??

Just thinking out loud now, but it seems your br0ker is really charging a premium for the cross.

Position size on nzd/usd would be roughly double that of eur/usd and that will give even exposure. If you match pip values you are going to be about 2:1 on your euro exposure and I don't think that's what you want.
