There is actually one that trades only the EUR/USD on H1.
A pair that is quite a slow mover in comparison, but offers great stability.
Not too spiky in its movement with a small daily range.
Maybe that's why its so successful trading this pair.

Its success rate is only about
75% as you can see from the long & short trades won.
But the biggest SL is only
22 pips. And max draw down was only
7%. That's pretty stable.
Not bad,considering
1245 trades executed over a period of 5 months with conservative compounding.
LIVE trading was done through Alpari.

I remember about a year ago there was a big scam on a Russian broker. Vladislav or something the trader's name. Basically they alter the result on the broker's side and it appears on myfxbook to be a profitable system. Many lost their money. Unless you are using a reliable broker, it's better not to trust.
