Quote from asap:
on top of this, you have to neutralize the currencies involved in order to keep the spread immune from FX influence, otherwise you are also involved in a FX spread transaction.
This is the aspect I am concerned about overlooking -- basically putting on a EUR/GBP trade. But unless there is a major move in the pair, I think the effect should be relatively minimal -- do you agree?
Using the formula I put up earlier, the spread does trend pretty nicely, even if the esignal spread tool is a bit crude. I would rather construct spreads using the bid and the ask, rather than the last price.
Thanks to everyone for their replies.
