You’ve read it right, the headline says one currency, not a pair. Most often currency exchange traders target one the pairs, but they miss a lot of good trading positions on other currency pairs. There is a middle ground and it’s possible to focus on one currency of several pairs.
Certain Forex EA creators have made a decision to do exactly that and created GBPBOT. This Forex robot works on the GBP and its pairs. The benefit that it gives won’t be immediatelly apparent, though. Naturally, traders are used to trade the pairs and not single currencies (that doesn’t even sound correct), so why target one now?
The answer lies in the idea of link between different currency pairs. You see, the pairs where the same currency is involved are linked and act in a similar way. That is to say, if one pair is moving in one direction, others with the same currency might be moving in the same direction too. But that won’t be that obvious so we use that link. And you can see where it’s handy for forex trading EA development.
