Which Brokers Best Support Signals?

 
I'm looking at some brokers and any other recommendations. Must be an offshore broker that accepts US clients. Any ideas? Must allow hedging too. 
 

It depends on the signal, check the Slippage tab of the signal that interests you to find the best setup for copying it.

Green and upper yellow values are best, orange and red are to be avoided.
