don't mean any disrespect to you but you're being too close-minded. Whilst a good percentage of fx traders are technical, the big moves are swayed by serious fundamentals. The mover the last two days can be soley contributed to by the lower than expected final Q1 GDP. Whilst the current account was higher than expected GBP is a lot more important to the boe wrt the base rate which from the last meeting is looking more likely that there will be no rate hike and a good possibility of a rate cut. THe previous meeting was at 7-2 with the ratio surely to decrease with the onset of more bad economic data. Please keep this in mind and perhasp code these into your EAs as I have done and you will not only prevent any losses from trend reversals or wild swings caused by fundamentals ,but also get in on these huge moves.
