Broker with lowest swap/rollover costs?

I'm looking for a new broker and hoping someone can point me in the right direction.

I'm in UK and I trade a kind of hedged grid system in which trades may often be kept open for very long periods. So keeping swap/rollover costs to an absolute minimum is particulary important to me. Also, highish leverage would be an advantage...

So... can anyone recommend an (established) broker who offers very low swap/rollover costs?

Thanks in advance

you would need to find a broker who offsets the longs and shorts and calculates swap on the balance.

I would like to know too which brokers do this.......

Activtrades

Yes I was thinking the same, duxis, and I may well end up with Activtrades.

But I've discovered that there are a few brokers around that offer swap free accounts (even for a non Islam account). This would be SUCH an advantage for my way of trading, but these brokers are mostly non uk and not known to me, so I am a little reluctant to go there... Anyone had experience of any of the swap free brokers mentioned here:
