Check out 2 advance potential patterns on the GBPJPY 4H chart, one with a opportunity and the other with a opportunity. Risk/reward profiles are good in both case. In this case, you can place limit orders in both directions and wait and see. If one hits, you can cancel the other order. If you want to be really aggressive, you can even leave both orders on and if one hits, wait for the second one to hit in the opposite direction. Targets at 382 and 618 retracements.
Good luck in the markets !
