it sounds like a nice strategy but l dont understand why you prefer +30 and -30 distance .l think it is too far .l will prefer 15 or 20 pips distance and it can let you make more profit.and l like your stoploss policy l am sure it will work also for gbpjpy since this pair is very similar with eurjpy and they both make large moves daily.some times can move more tan 200 pips .l will add this strategy to may daily trading.thnx for the share.
