Good response. I do get what you're trying to do. Your instincts are good and close to what actually goes down in the money markets. You're one of the few taking the job seriously which is why I took the time to ask the questions I did. But like many hobbyist traders you're not committing and you're too short term. The individual currencies are correlated only in that at any given point in time one is stronger/weaker than another. You can get that from looking at the price alone. What you potentially have is a context within which to bias yourself. I bet all those times the pair you were trading that weren't behaving like your lines say they should you thought your system was at fault. It isn't. If you enabled your analysis for a longer period and then trade the regressions back toward what your lines are telling you, which is going to be when the price is as far out of whack with what you think it should be according to those lines, you'll see what I'm talking about. You also need to stick in some committed funds into the enterprise to get yourself to take it and yourself seriously, and also to get properly paid for your efforts. Hate to see talent wasted almost as much as I do so see it go unrewarded. Nothing wrong with flipping burgers or doing whatever day job you got wright now, but what you have is painfully close to printing your own money. Don't blow it.
