On my real trading account I use different currency instruments. Whole system based on different expert advisors, wich I wrote myself for myself.
For my system Forex Artist I use the best (at my opinion) signals from my EA's. Basically I use only one pair EURUSD for GF site. Easy to follow signals which I issue one or two times per day, mostly at 10-11 am (Moscow time) and 15-16 pm.
