Which brokers are 24/7 ?

I am with CMS and have been reasonably happy with. However, last 12 hours were not good:
1) I had a cable long entry stop set just above Friday's high at 9355, but it got filled at 9435! - this position is now 70 pips down
2) I was still sitting on a short @ 9311 (yes, I know, stupid to try and pick tops) but with limit set to breakeven and that did not get filled an hour ago even though price touch 9305 on my chart. Now price is moving against again and I am not sure it will come back to that level short term.

Many referred to Oanda as a broker that never closes. Is that the only one? Or are there others and which are they?

Thanks!

Yes, OANDA never closes, in that they will let you place orders on the weekend if you want. However they're spreads are increased during the weekend (to 10 pips on all the majors) because of the low volatility.
