Actually, in those type of broker you can do it with other similar pair, you can 'protect' your GBPJPY south retracement by open Sell at EURJPY that actually go south faster than GBPJPY at this moment. but maybe for right now it is little bit too late. I think all JPY pair only 'in retrace' since that Japanese government so desperately wanna make their Yen more cheaper whatever it takes..
But yes, I do not stress too much since I too see it as a retrace, not a reversal. Not only because of Japanese wish for weak Yen, but also from what I see on charts. But as you know, I would much rather have caught 100 or 150 pips in a short position (and catch it as well on the way back up) than to sit and wait out the retrace...
That leaves me with making pennies on other pairs. EurUsd moves so little the snails overtake it. I am a speed freak. AudUsd is usually a pretty good 'stable' one as well, but you wait 4 hours to reach 30 pips usually, before a retrace. If you want more than that, you have to wait.
Yes, it is too late now to Hedge elsewhere. If I really get bored I will scalp on other pairs, and long scalps on GY as well.
