Disliked{quote} GBP/USD going up, USD/JPY going down. Add GBPJPY to your analysis: If it is going down, then sell USDJPY; if going up, buy GBPUSD.Ignored
i.e. you don't directly trade GBP against the Yen The GBPJPY price is dictated by GBP against the USD, and USD against the Yen.
GBPJPY will go up:
1. if both USDJPY and GBPUSD are rising (and vice versa for falling GPPJPY)
2. USDJPY is rising faster than weakness in the GBPUSD
3. GBPUSD is rising faster than weakness in the USDJPY
