Brought BlackDiamondEa V7.5 price with 300$. It can trade with any pair. But support told me the EURUSD pair is best for this system, which provides 90% trading accuracy. & it's true when I use this system.
On forex, we need profit, No need for how much pair its work.
Finally, I am happy with this system.
Google it & you will find their website. Try to buy the original version of EA from the vendor, which provides you with the best set file too, Which is good.
